Runs when the entire object graph has been deserialized. The object that initiated the callback. Defines the string comparison options to use with . Indicates that the string comparison must ignore case. Indicates that the string comparison must ignore the Kana type. Kana type refers to Japanese hiragana and katakana characters, which represent phonetic sounds in the Japanese language. Hiragana is used for native Japanese expressions and words, while katakana is used for words borrowed from other languages, such as "computer" or "Internet". A phonetic sound can be expressed in both hiragana and katakana. If this value is selected, the hiragana character for one sound is considered equal to the katakana character for the same sound. Indicates that the string comparison must ignore nonspacing combining characters, such as diacritics. The Unicode Standard defines combining characters as characters that are combined with base characters to produce a new character. Nonspacing combining characters do not occupy a spacing position by themselves when rendered. Indicates that the string comparison must ignore symbols, such as white-space characters, punctuation, currency symbols, the percent sign, mathematical symbols, the ampersand, and so on. Indicates that the string comparison must ignore the character width. For example, Japanese katakana characters can be written as full-width or half-width. If this value is selected, the katakana characters written as full-width are considered equal to the same characters written as half-width. Indicates the default option settings for string comparisons. Indicates that the string comparison must use successive Unicode UTF-16 encoded values of the string (code unit by code unit comparison), leading to a fast comparison but one that is culture-insensitive. A string starting with a code unit XXXX16 comes before a string starting with YYYY16, if XXXX16 is less than YYYY16. This value cannot be combined with other values and must be used alone. String comparison must ignore case, then perform an ordinal comparison. This technique is equivalent to converting the string to uppercase using the invariant culture and then performing an ordinal comparison on the result. Indicates that the string comparison must use the string sort algorithm. In a string sort, the hyphen and the apostrophe, as well as other nonalphanumeric symbols, come before alphanumeric characters.

Determines the action that occurs when the or method is invoked on a with a . Changes are cascaded across the relationship. No action occurs (default). Provides a description of the results of the query and its effect on the database. When the command is executed, the associated Connection object is closed when the associated DataReader object is closed. The query may return multiple result sets. Execution of the query may affect the database state. Default sets no flags, so calling ExecuteReader(CommandBehavior.Default) is functionally equivalent to calling ExecuteReader(). The query returns column and primary key information. The query returns column information only. When using , the .NET Framework Data Provider for SQL Server precedes the statement being executed with SET FMTONLY ON. Provides a way for the DataReader to handle rows that contain columns with large binary values. Rather than loading the entire row, SequentialAccess enables the DataReader to load data as a stream. You can then use the GetBytes or GetChars method to specify a byte location to start the read operation, and a limited buffer size for the data being returned. The query returns a single result set. The query is expected to return a single row of the first result set. Execution of the query may affect the database state. Some .NET Framework data providers may, but are not required to, use this information to optimize the performance of the command. When you specify with the method of the object, the .NET Framework Data Provider for OLE DB performs binding using the OLE DB IRow interface if it is available. Otherwise, it uses the IRowset interface. If your SQL statement is expected to return only a single row, specifying can also improve application performance. It is possible to specify SingleRow when executing queries that are expected to return multiple result sets. In that case, where both a multi-result set SQL query and single row are specified, the result returned will contain only the first row of the first result set. The other result sets of the query will not be returned. Specifies how a command string is interpreted. The name of a stored procedure. The name of a table. An SQL text command. (Default.)

Combine with Write for read/write access. Read and write access to the file. Data can be written to and read from the file. Write access to the file. Data can be written to the file. Combine with Read for read/write access. Provides attributes for files and directories. The file is a candidate for backup or removal. The file is compressed. Reserved for future use. The file is a directory. The file or directory is encrypted. For a file, this means that all data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and directories. The file is hidden, and thus is not included in an ordinary directory listing. The file or directory includes data integrity support. When this value is applied to a file, all data streams in the file have integrity support. When this value is applied to a directory, all new files and subdirectories within that directory, by default, include integrity support. The file is a standard file that has no special attributes. This attribute is valid only if it is used alone. The file or directory is excluded from the data integrity scan. When this value is applied to a directory, by default, all new files and subdirectories within that directory are excluded from data integrity. The file will not be indexed by the operating system's content indexing service. The file is offline. The data of the file is not immediately available. The file is read-only. The file contains a reparse point, which is a block of user-defined data associated with a file or a directory. The file is a sparse file. Sparse files are typically large files whose data consists of mostly zeros. The file is a system file. That is, the file is part of the operating system or is used exclusively by the operating system. The file is temporary. A temporary file contains data that is needed while an application is executing but is not needed after the application is finished. File systems try to keep all the data in memory for quicker access rather than flushing the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.

For the default binder, bindingAttr includes , and match is null or an empty array. -or- bindingAttr includes , and value is null. Selects a method to invoke from the given set of methods, based on the supplied arguments. A bitwise combination of values. The set of methods that are candidates for matching. For example, when a object is used by , this parameter specifies the set of methods that reflection has determined to be possible matches, typically because they have the correct member name. The default implementation provided by changes the order of this array. The arguments that are passed in. The binder can change the order of the arguments in this array; for example, the default binder changes the order of arguments if the names parameter is used to specify an order other than positional order. If a binder implementation coerces argument types, the types and values of the arguments can be changed as well. An array of parameter modifiers that enable binding to work with parameter signatures in which the types have been modified. The default binder implementation does not use this parameter. An instance of that is used to control the coercion of data types, in binder implementations that coerce types. If culture is null, the for the current thread is used. Note For example, if a binder implementation allows coercion of string values to numeric types, this parameter is necessary to convert a String that represents 1000 to a Double value, because 1000 is represented differently by different cultures. The default binder does not do such string coercions. The parameter names, if parameter names are to be considered when matching, or null if arguments are to be treated as purely positional. For example, parameter names must be used if arguments are not supplied in positional order. After the method returns, state contains a binder-provided object that keeps track of argument reordering. The binder creates this object, and the binder is the sole consumer of this object. If state is not null when BindToMethod returns, you must pass state to the method if you want to restore args to its original order, for example, so that you can retrieve the values of ref parameters (ByRef parameters in Visual Basic). The matching method. For the default binder, match contains multiple methods that are equally good matches for args. For example, args contains a MyClass object that implements the IMyClass interface, and match contains a method that takes MyClass and a method that takes IMyClass. For the default binder, match contains no methods that can accept the arguments supplied in args. For the default binder, match is null or an empty array. Changes the type of the given Object to the given Type. The object to change into a new Type. The new Type that value will become. An instance of that is used to control the coercion of data types. If culture is null, the for the current thread is used. Note For example, this parameter is necessary to convert a String that represents 1000 to a Double value, because 1000 is represented differently by different cultures. An object that contains the given value as the new type. Upon returning from , restores the args argument to what it was when it came from BindToMethod. The actual arguments that are passed in. Both the types and values of the arguments can be changed. A binder-provided object that keeps track of argument reordering. Selects a method from the given set of methods, based on the argument type. A bitwise combination of values. The set of methods that are candidates for matching. For example, when a object is used by , this parameter specifies the set of methods that reflection has determined to be possible matches, typically because they have the correct member name. The default implementation provided by changes the order of this array. The parameter types used to locate a matching method. An array of parameter modifiers that enable binding to work with parameter signatures in which the types have been modified. The matching method, if found; otherwise, null. For the default binder, match contains multiple methods that are equally good matches for the parameter types described by types. For example, the array in types contains a object for MyClass and the array in match contains a method that takes a base class of MyClass and a method that takes an interface that MyClass implements. For the default binder, match is null or an empty array. -or- An element of types derives from , but is not of type RuntimeType. Selects a property from the given set of properties, based on the specified criteria. A bitwise combination of values. The set of properties that are candidates for matching. For example, when a object is used by , this parameter specifies the set of properties that reflection has determined to be possible matches, typically because they have the correct member name. The default implementation provided by changes the order of this array. The return value the matching property must have. The index types of the property being searched for. Used for index properties such as the indexer for a class. An array of parameter modifiers that enable binding to work with parameter signatures in which the types have been modified. The matching property. For the default binder, match contains multiple properties that are equally good matches for returnType and indexes. For the default binder, match is null or an empty array. Specifies flags that control binding and the way in which the search for members and types is conducted by reflection. Specifies that reflection should create an instance of the specified type. Calls the constructor that matches the given arguments. The supplied member name is ignored. If the type of lookup is not specified, (Instance | Public) will apply. It is not possible to call a type initializer. This flag is passed to an InvokeMember method to invoke a constructor. Specifies that only members declared at the level of the supplied type's hierarchy should be considered. Inherited members are not considered. Specifies that no binding flags are defined. Specifies that types of the supplied arguments must exactly match the types of the corresponding formal parameters. Reflection throws an exception if the caller supplies a non-null Binder object, since that implies that the caller is supplying BindToXXX implementations that will pick the appropriate method. Specifies that public and protected static members up the hierarchy should be returned. Private static members in inherited classes are not returned. Static members include fields, methods, events, and properties. Nested types are not returned. Specifies that the value of the specified field should be returned. This flag is passed to an InvokeMember method to get a field value. Specifies that the value of the specified property should be returned. This flag is passed to an InvokeMember method to invoke a property getter. Specifies that the case of the member name should not be considered when binding. Used in COM interop to specify that the return value of the member can be ignored. Specifies that instance members are to be included in the search. Specifies that a method is to be invoked. This must not be a constructor or a type initializer. This flag is passed to an InvokeMember method to invoke a method. Specifies that non-public members are to be included in the search. Returns the set of members whose parameter count matches the number of supplied arguments. This binding flag is used for methods with parameters that have default values and methods with variable arguments (varargs). This flag should only be used with . Specifies that public members are to be included in the search. Specifies that the PROPPUT member on a COM object should be invoked. PROPPUT specifies a property-setting function that uses a value. Use PutDispProperty if a property has both PROPPUT and PROPPUTREF and you need to distinguish which one is called. Specifies that the PROPPUTREF member on a COM object should be invoked. PROPPUTREF specifies a property-setting function that uses a reference instead of a value. Use PutRefDispProperty if a property has both PROPPUT and PROPPUTREF and you need to distinguish which one is called. Specifies that the value of the specified field should be set. This flag is passed to an InvokeMember method to set a field value. Specifies that the value of the specified property should be set. For COM properties, specifying this binding flag is equivalent to specifying PutDispProperty and PutRefDispProperty. This flag is passed to an InvokeMember method to invoke a property setter. Specifies that static members are to be included in the search. Not implemented. Defines the valid calling conventions for a method. Specifies that either the Standard or the VarArgs calling convention may be used. Specifies that the signature is a function-pointer signature, representing a call to an instance or virtual method (not a static method). If ExplicitThis is set, HasThis must also be set. The first argument passed to the called method is still a this pointer, but the type of the first argument is now unknown. Therefore, a token that describes the type (or class) of the this pointer is explicitly stored into its metadata signature. Specifies an instance or virtual method (not a static method). At run-time, the called method is passed a pointer to the target object as its first argument (the this pointer). The signature stored in metadata does not include the type of this first argument, because the method is known and its owner class can be discovered from metadata. Specifies the default calling convention as determined by the common language runtime. Use this calling convention for static methods. For instance or virtual methods use HasThis. Specifies the calling convention for methods with variable arguments. Discovers the attributes of a class constructor and provides access to constructor metadata.

Invokes the constructor reflected by the instance that has the specified parameters, providing default values for the parameters not commonly used. An array of values that matches the number, order and type (under the constraints of the default binder) of the parameters for this constructor. If this constructor takes no parameters, then use either an array with zero elements or null, as in Object[] parameters = new Object[0]. Any object in this array that is not explicitly initialized with a value will contain the default value for that object type. For reference-type elements, this value is null. For value-type elements, this value is 0, 0.0, or false, depending on the specific element type. An instance of the class associated with the constructor. The class is abstract. -or- The constructor is a class initializer.

One of the BindingFlags values that specifies the type of binding. A Binder that defines a set of properties and enables the binding, coercion of argument types, and invocation of members using reflection. If binder is null, then Binder.DefaultBinding is used. An array of type Object used to match the number, order and type of the parameters for this constructor, under the constraints of binder. If this constructor does not require parameters, pass an array with zero elements, as in Object[] parameters = new Object[0]. Any object in this array that is not explicitly initialized with a value will contain the default value for that object type. For reference-type elements, this value is null. For value-type elements, this value is 0, 0.0, or false, depending on the specific element type. A used to govern the coercion of types. If this is null, the for the current thread is used.

The findValue parameter for the method must be a string representing either the application policy friendly name or the object identifier (OID, or ) of the certificate. For example, "Encrypting File System" or "1.3.6.1.4.1.311.10.3.4" can be used. For an application that will be localized, the OID value must be used, because the friendly name is localized. The findValue parameter for the method must be a string representing either the friendly name or the object identifier (OID, or ) of the certificate policy. The best practice is to use the OID, such as "1.3.6.1.4.1.311.10.3.4". For an application that will be localized, the OID must be used, because the friendly name is localized. The findValue parameter for the method must be a string describing the extension to find. The object identifier (OID) is most commonly used to direct the method to search for all certificates that have an extension matching that OID value. The findValue parameter for the method must be a string representing the issuer distinguished name of the certificate. This is a more specific search than that provided by the enumeration value. Using the value, the method performs a case-insensitive string comparison for the entire distinguished name. Searching by issuer name is a less precise search. The findValue parameter for the method must be a string representing the issuer name of the certificate. This is a less specific search than that provided by the enumeration value. Using the value, the method performs a case-insensitive string comparison using the supplied value. For example, if you pass "MyCA" to the method, it will find all certificates with the issuer name containing that string, regardless of other issuer values. The findValue parameter for the method must be either a string representing the key usage or an integer representing a bit mask containing all the requested key usages. For the string value, only one key usage at a time can be specified, but the method can be used in a cascading sequence to get the intersection of the requested usages. For example, the findValue parameter can be set to "KeyEncipherment" or an integer (0x30 indicates "KeyEncipherment" and "DataEncipherment"). Values of the enumeration can also be used. The findValue parameter for the method must be a string that represents the serial number of the certificate as displayed by the certificate dialog box, but without the spaces, or as returned by the method. The findValue parameter for the method must be a string representing the subject distinguished name of the certificate. This is a more specific search than that provided by the enumeration value. Using the value, the method performs a case-insensitive string comparison for the entire distinguished name. Searching by subject name is a less precise search. The findValue parameter for the method must be a string representing the subject key identifier in hexadecimal, such as "F3E815D45E83B8477B9284113C64EF208E897112", as displayed in the UI. The findValue parameter for the method must be a string representing the subject name of the certificate. This is a less specific search than that provided by the enumeration value. Using the value, the method performs a case-insensitive string comparison using the supplied value. For example, if you pass "MyCert" to the method, it will find all certificates with the subject name containing that string, regardless of other subject values. Searching by distinguished name is a more precise search. The findValue parameter for the method must be a string representing the template name of the certificate, such as "ClientAuth". A template name is an X509 version 3 extension that specifies the uses of the certificate. The findValue parameter for the method must be a string representing the thumbprint of the certificate. The findValue parameter for the method must be a value in local time. For example, you can find all the certificates that will be valid until the end of the year by eliminating the results of a operation for of the last day of the year from the results of a operation for . The findValue parameter for the method must be a value in local time. The value does not have to be in the future. For example, you can use to find certificates that became valid in the current year by taking the intersection of the results of a operation for for the last day of last year with the results of a operation for of . The findValue parameter for the method must be a value in local time. You can use to find all the currently valid certificates.

Defines where and how to import the private key of an X.509 certificate. The default key set is used. The user key set is usually the default. Imported keys are marked as exportable. Private keys are stored in the local computer store rather than the current user store. The key associated with a PFX file is persisted when importing a certificate. Private keys are stored in the current user store rather than the local computer store. This occurs even if the certificate specifies that the keys should go in the local computer store.

Adds the necessary columns and primary key information to complete the schema. For more information about how primary key information is added to a , see .To function properly with the .NET Framework Data Provider for OLE DB, AddWithKey requires that the native OLE DB provider obtains necessary primary key information by setting the DBPROP_UNIQUEROWS property, and then determines which columns are primary key columns by examining DBCOLUMN_KEYCOLUMN in the IColumnsRowset. As an alternative, the user may explicitly set the primary key constraints on each . This ensures that incoming records that match existing records are updated instead of appended. When using AddWithKey, the .NET Framework Data Provider for SQL Server appends a FOR BROWSE clause to the statement being executed. The user should be aware of potential side effects, such as interference with the use of SET FMTONLY ON statements. See SQL Server Books Online for more information.

Specifies that sorts should be based on a characters numeric value instead of its alphabetical value. Performs a binary sort. Specifies that comparisons must ignore case. Specifies that comparisons must ignore the Kana type. Kana type refers to Japanese hiragana and katakana characters that represent phonetic sounds in the Japanese language. Hiragana is used for native Japanese expressions and words, while katakana is used for words borrowed from other languages, such as "computer" or "Internet". A phonetic sound can be expressed in both hiragana and katakana. If this value is selected, the hiragana character for one sound is considered equal to the katakana character for the same sound. Specifies that comparisons must ignore nonspace combining characters, such as diacritics. The Unicode Standard defines combining characters as characters that are combined with base characters to produce a new character. Non-space combining characters do not use character space by themselves when rendered. For more information about non-space combining characters, see the Unicode Standard at http://www.unicode.org. Specifies that comparisons must ignore the character width. For example, Japanese katakana characters can be written as full-width or half-width and, if this value is selected, the katakana characters written as full-width are considered equal to the same characters written in half-width. Specifies the default option settings for comparisons.

Permissions to access the constructor of type T were missing. Type T does not have a default constructor. Specifies how a instance synchronizes access among multiple threads. Locks are used to ensure that only a single thread can initialize a instance in a thread-safe manner. If the initialization method (or the default constructor, if there is no initialization method) uses locks internally, deadlocks can occur. If you use a constructor that specifies an initialization method (valueFactory parameter), and if that initialization method throws an exception (or fails to handle an exception) the first time you call the property, then the exception is cached and thrown again on subsequent calls to the property. If you use a constructor that does not specify an initialization method, exceptions that are thrown by the default constructor for T are not cached. In that case, a subsequent call to the property might successfully initialize the instance. If the initialization method recursively accesses the property of the instance, an is thrown. The instance is not thread safe; if the instance is accessed from multiple threads, its behavior is undefined. Use this mode only when high performance is crucial and the instance is guaranteed never to be initialized from more than one thread. If you use a constructor that specifies an initialization method (valueFactory parameter), and if that initialization method throws an exception (or fails to handle an exception) the first time you call the property, then the exception is cached and thrown again on subsequent calls to the property. If you use a constructor that does not specify an initialization method, exceptions that are thrown by the default constructor for T are not cached. In that case, a subsequent call to the property might successfully initialize the instance. If the initialization method recursively accesses the property of the instance, an is thrown. When multiple threads try to initialize a instance simultaneously, all threads are allowed to run the initialization method (or the default constructor, if there is no initialization method). The first thread to complete initialization sets the value of the instance. That value is returned to any other threads that were simultaneously running the initialization method, unless the initialization method throws exceptions on those threads. Any instances of T that were created by the competing threads are discarded. If the initialization method throws an exception on any thread, the exception is propagated out of the property on that thread. The exception is not cached. The value of the property remains false, and subsequent calls to the property, either by the thread where the exception was thrown or by other threads, cause the initialization method to run again. If the initialization method recursively accesses the property of the instance, no exception is thrown. Defines the lock that implements single-writer/multiple-reader semantics. This is a value type.

The query execution mode is a hint that specifies how the system should handle performance trade-offs when parallelizing queries. This is the default setting. PLINQ will examine the query's structure and will only parallelize the query if will likely result in speedup. If the query structure indicates that speedup is not likely to be obtained, then PLINQ will execute the query as an ordinary LINQ to Objects query. Parallelize the entire query, even if that means using high-overhead algorithms. Use this flag in cases where you know that parallel execution of the query will result in speedup, but PLINQ in the Default mode would execute it as sequential. Specifies the preferred type of output merge to use in a query. In other words, it indicates how PLINQ should merge the results from the various partitions back into a single result sequence. This is a hint only, and may not be respected by the system when parallelizing all queries. Use a merge with output buffers of a size chosen by the system. Results will accumulate into an output buffer before they are available to the consumer of the query. Use the default merge type, which is AutoBuffered. Use a merge with full output buffers. The system will accumulate all of the results before making any of them available to the consumer of the query. Use a merge without output buffers.

Specifies the behavior for a task that is created by using the or method. Specifies that the continuation, if it is a child task, is attached to a parent in the task hierarchy. The continuation can be a child task only if its antecedent is also a child task. By default, a child task (that is, an inner task created by an outer task) executes independently of its parent. You can use the option so that the parent and child tasks are synchronized. Note that if a parent task is configured with the option, the option in the child task has no effect, and the child task will execute as a detached child task. For more information, see Attached and Detached Child Tasks. Specifies that any child task (that is, any nested inner task created by this continuation) that is created with the option and attempts to execute as an attached child task will not be able to attach to the parent task and will execute instead as a detached child task. For more information, see Attached and Detached Child Tasks. Specifies that the continuation task should be executed synchronously. With this option specified, the continuation runs on the same thread that causes the antecedent task to transition into its final state. If the antecedent is already complete when the continuation is created, the continuation will run on the thread that creates the continuation. If the antecedent's is disposed in a finally block (Finally in Visual Basic), a continuation with this option will run in that finally block. Only very short-running continuations should be executed synchronously. Because the task executes synchronously, there is no need to call a method such as to ensure that the calling thread waits for the task to complete. Specifies that tasks created by the continuation by calling methods such as or see the default scheduler () rather than the scheduler on which this continuation is running as the current scheduler. In the case of continuation cancellation, prevents completion of the continuation until the antecedent has completed. Specifies that a continuation will be a long-running, course-grained operation. It provides a hint to the that oversubscription may be warranted. When no continuation options are specified, specifies that default behavior should be used when executing a continuation. The continuation runs asynchronously when the antecedent task completes, regardless of the antecedent's final property value. It the continuation is a child task, it is created as a detached nested task. Specifies that the continuation task should not be scheduled if its antecedent was canceled. An antecedent is canceled if its property upon completion is . This option is not valid for multi-task continuations. Specifies that the continuation task should not be scheduled if its antecedent threw an unhandled exception. An antecedent throws an unhandled exception if its property upon completion is . This option is not valid for multi-task continuations. Specifies that the continuation task should not be scheduled if its antecedent ran to completion. An antecedent runs to completion if its property upon completion is . This option is not valid for multi-task continuations. Specifies that the continuation should be scheduled only if its antecedent was canceled. An antecedent is canceled if its property upon completion is . This option is not valid for multi-task continuations. Specifies that the continuation task should be scheduled only if its antecedent threw an unhandled exception. An antecedent throws an unhandled exception if its property upon completion is . The option guarantees that the property in the antecedent is not null. You can use that property to catch the exception and see which exception caused the task to fault. If you do not access the property, the exception is unhandled. Also, if you attempt to access the property of a task that has been canceled or has faulted, a new exception is thrown. This option is not valid for multi-task continuations. Specifies that the continuation should be scheduled only if its antecedent ran to completion. An antecedent runs to completion if its property upon completion is . This option is not valid for multi-task continuations. A hint to a to schedule task in the order in which they were scheduled, so that tasks scheduled sooner are more likely to run sooner, and tasks scheduled later are more likely to run later. Specifies that the continuation task should be run asynchronously. This option has precedence over . Specifies flags that control optional behavior for the creation and execution of tasks. Specifies that a task is attached to a parent in the task hierarchy. By default, a child task (that is, an inner task created by an outer task) executes independently of its parent. You can use the option so that the parent and child tasks are synchronized. Note that if a parent task is configured with the option, the option in the child task has no effect, and the child task will execute as a detached child task. For more information, see Attached and Detached Child Tasks. Specifies that any child task that attempts to execute as an attached child task (that is, it is created with the option) will not be able to attach to the parent task and will execute instead as a detached child task. For more information, see Attached and Detached Child Tasks. Prevents the ambient scheduler from being seen as the current scheduler in the created task. This means that operations like StartNew or ContinueWith that are performed in the created task will see as the current scheduler. Specifies that a task will be a long-running, coarse-grained operation involving fewer, larger components than fine-grained systems. It provides a hint to the that oversubscription may be warranted. Oversubscription lets you create more threads than the available number of hardware threads. It also provides a hint to the task scheduler that an additional thread might be required for the task so that it does not block the forward progress of other threads or work items on the local thread-pool queue. Specifies that the default behavior should be used. A hint to a to schedule a task in as fair a manner as possible, meaning that tasks scheduled sooner will be more likely to be run sooner, and tasks scheduled later will be more likely to be run later.

Instructs the just-in-time (JIT) compiler to use its default behavior, which includes enabling optimizations, disabling Edit and Continue support, and using symbol store sequence points if present. Starting with the .NET Framework version 2.0, JIT tracking information, the Microsoft intermediate language (MSIL) offset to the native-code offset within a method, is always generated. Disable optimizations performed by the compiler to make your output file smaller, faster, and more efficient. Optimizations result in code rearrangement in the output file, which can make debugging difficult. Typically optimization should be disabled while debugging. In versions 2.0 or later, combine this value with Default (Default | DisableOptimizations) to enable JIT tracking and disable optimizations. Enable edit and continue. Edit and continue enables you to make changes to your source code while your program is in break mode. The ability to edit and continue is compiler dependent. Use the implicit MSIL sequence points, not the program database (PDB) sequence points. The symbolic information normally includes at least one Microsoft intermediate language (MSIL) offset for each source line. When the just-in-time (JIT) compiler is about to compile a method, it asks the profiling services for a list of MSIL offsets that should be preserved. These MSIL offsets are called sequence points. Starting with the .NET Framework version 2.0, JIT tracking information is always generated, and this flag has the same effect as , except that it sets the property to false. However, because JIT tracking is always enabled, the property value is ignored in version 2.0 or later. Note that, unlike the flag, the flag cannot be used to disable JIT optimizations.

The Framework will throw an if you try to use this member. Specifies caching behavior for resources obtained using the Hypertext Transfer protocol (HTTP). Satisfies a request by using the server. No entries are taken from caches, added to caches, or removed from caches between the client and server. No entries are taken from caches, added to caches, or removed from caches between the client and server. This is the default cache behavior specified in the machine configuration file that ships with the .NET Framework. Satisfies a request for a resource from the cache if the resource is available; otherwise, sends a request for a resource to the server. If the requested item is available in any cache between the client and the server, the request might be satisfied by the intermediate cache. Satisfies a request using the locally cached resource; does not send a request for an item that is not in the cache. When this cache policy level is specified, a exception is thrown if the item is not in the client cache. Satisfies a request for a resource either from the local computer's cache or a remote cache on the local area network. If the request cannot be satisfied, a exception is thrown. In the HTTP caching protocol, this is achieved using the only-if-cached cache control directive. Satisfies a request for a resource either by using the cached copy of the resource or by sending a request for the resource to the server. The action taken is determined by the current cache policy and the age of the content in the cache. This is the cache level that should be used by most applications. Never satisfies a request by using resources from the cache and does not cache resources. If the resource is present in the local cache, it is removed. This policy level indicates to intermediate caches that they should remove the resource. In the HTTP caching protocol, this is achieved using the no-cache cache control directive. Satisfies a request by using the server or a cache other than the local cache. Before the request can be satisfied by an intermediate cache, that cache must revalidate its cached entry with the server. In the HTTP caching protocol, this is achieved using the max-age = 0 cache control directive and the no-cache Pragma header. Satisfies a request by using the server. The response might be saved in the cache. In the HTTP caching protocol, this is achieved using the no-cache cache control directive and the no-cache Pragma header. Compares the copy of the resource in the cache with the copy on the server. If the copy on the server is newer, it is used to satisfy the request and replaces the copy in the cache. If the copy in the cache is the same as the server copy, the cached copy is used. In the HTTP caching protocol, this is achieved using a conditional request.

Provides an internal interface for accessing the arguments of multiple tree nodes (DynamicExpression, ElementInit, MethodCallExpression, InvocationExpression, NewExpression, and InexExpression). You should not use this API. It is only public due to DLL refactoring and exists only for internal performance optimizations.

This enables two optimizations which reduce the size of expression trees. The first enables the tree nodes to hold onto an IList instead of a ReadOnlyCollection. IList saves the cost of allocating the ReadOnlyCollection for each node. The second enables creating specialized subclasses that hold onto a specific number of arguments (for example, Block2, Block3, Block4). Therefore, these nodes avoid allocating both a ReadOnlyCollection and an array for storing their elements, saving 32 bytes per node.

The expression tree nodes continue to expose the original LINQ properties of ReadOnlyCollections. The nodes do this by re-using a field for storing both the array or an element that would normally be stored in the array.

For the array case, the collection is typed to IList instead of ReadOnlyCollection. When the node is initially constructed it is an array. When the compiler accesses the members it uses this interface. Accessing array elements promotes the array to a ReadOnlyCollection.

For the object case we store the first argument in a field typed to object. When the node is initially constructed, the field holds the Expression. The compiler accesses arguments through this interface, and the accessor for the first argument uses Expression.ReturnObject to return the object that handles the Expression or ReadOnlyCollection case. When the user accesses the ReadOnlyCollection, then the object field is updated to hold directly onto the ReadOnlyCollection.

It is important that the Expressions consistently return the same ReadOnlyCollection. Otherwise, the re-writer tree walker will break. It is a breaking change from LINQ v1 to return different ReadOnlyCollections form the same Expression node. Currently users can rely on object identity to tell if the node has changed. Storing the ReadOnlyCollection in an overloaded field both reduces memory usage and maintains compatibility for the public API.

This occurs when the source computer's output queue has insufficient storage space, or when packets arrive at the destination too quickly to be processed. The ICMP echo request succeeded; an ICMP echo reply was received. When you get this status code, the other properties contain valid data. The ICMP echo Reply was not received within the allotted time. The default time allowed for replies is 5 seconds. You can change this value using the or methods that take a timeout parameter. The ICMP echo request failed because its Time to Live (TTL) value reached zero, causing the forwarding node (router or gateway) to discard the packet. The ICMP echo request failed because its Time to Live (TTL) value reached zero, causing the forwarding node (router or gateway) to discard the packet. The ICMP echo request failed because the packet was divided into fragments for transmission and all of the fragments were not received within the time allotted for reassembly. RFC 2460 (available at www.ietf.org) specifies 60 seconds as the time limit within which all packet fragments must be received. The ICMP echo request failed for an unknown reason.

When overridden in a derived class, sets the asymmetric algorithm to use to create the signature. The instance of the implementation of to use to create the signature. Specifies the block cipher mode to use for encryption. The Cipher Block Chaining (CBC) mode introduces feedback. Before each plain text block is encrypted, it is combined with the cipher text of the previous block by a bitwise exclusive OR operation. This ensures that even if the plain text contains many identical blocks, they will each encrypt to a different cipher text block. The initialization vector is combined with the first plain text block by a bitwise exclusive OR operation before the block is encrypted. If a single bit of the cipher text block is mangled, the corresponding plain text block will also be mangled. In addition, a bit in the subsequent block, in the same position as the original mangled bit, will be mangled. The Cipher Feedback (CFB) mode processes small increments of plain text into cipher text, instead of processing an entire block at a time. This mode uses a shift register that is one block in length and is divided into sections. For example, if the block size is 8 bytes, with one byte processed at a time, the shift register is divided into eight sections. If a bit in the cipher text is mangled, one plain text bit is mangled and the shift register is corrupted. This results in the next several plain text increments being mangled until the bad bit is shifted out of the shift register. The default feedback size can vary by algorithm, but is typically either 8 bits or the number of bits of the block size. You can alter the number of feedback bits by using the property. Algorithms that support CFB use this property to set the feedback. The Cipher Text Stealing (CTS) mode handles any length of plain text and produces cipher text whose length matches the plain text length. This mode behaves like the CBC mode for all but the last two blocks of the plain text. The Electronic Codebook (ECB) mode encrypts each block individually. Any blocks of plain text that are identical and in the same message, or that are in a different message encrypted with the same key, will be transformed into identical cipher text blocks. Important: This mode is not recommended because it opens the door for multiple security exploits. If the plain text to be encrypted contains substantial repetition, it is feasible for the cipher text to be broken one block at a time. It is also possible to use block analysis to determine the encryption key. Also, an active adversary can substitute and exchange individual blocks without detection, which allows blocks to be saved and inserted into the stream at other points without detection. The Output Feedback (OFB) mode processes small increments of plain text into cipher text instead of processing an entire block at a time. This mode is similar to CFB; the only difference between the two modes is the way that the shift register is filled. If a bit in the cipher text is mangled, the corresponding bit of plain text will be mangled. However, if there are extra or missing bits from the cipher text, the plain text will be mangled from that point on. Accesses the cryptography configuration information.
