Member Function Documentation

Capture()

static ExecutionContext System.Threading.ExecutionContext.Capture ( )

static

Captures the execution context from the current thread.

Returns

An T:System.Threading.ExecutionContext object representing the execution context for the current thread.

Definition at line 686 of file ExecutionContext.cs.

CreateCopy()

ExecutionContext System.Threading.ExecutionContext.CreateCopy

(

)

Creates a copy of the current execution context.

Returns

An T:System.Threading.ExecutionContext object representing the current execution context.

Exceptions

T:System.InvalidOperationException

This context cannot be copied because it is used. Only newly captured contexts can be copied.

Definition at line 595 of file ExecutionContext.cs.

Dispose()

void System.Threading.ExecutionContext.Dispose

(

)

Releases all resources used by the current instance of the T:System.Threading.ExecutionContext class.

Implements System.IDisposable.

Definition at line 443 of file ExecutionContext.cs.

GetObjectData()

void System.Threading.ExecutionContext.GetObjectData	(	SerializationInfo	info,
		StreamingContext	context
	)

Sets the specified T:System.Runtime.Serialization.SerializationInfo object with the logical context information needed to recreate an instance of the current execution context.

Parameters

info	The T:System.Runtime.Serialization.SerializationInfo object to be populated with serialization information.
context	The T:System.Runtime.Serialization.StreamingContext structure representing the destination context of the serialization.

Exceptions

T:System.ArgumentNullException

info is null.

Implements System.Runtime.Serialization.ISerializable.

Definition at line 756 of file ExecutionContext.cs.

IsFlowSuppressed()

static bool System.Threading.ExecutionContext.IsFlowSuppressed ( )

static

Indicates whether the flow of the execution context is currently suppressed.

Returns

true if the flow is suppressed; otherwise, false.

Definition at line 676 of file ExecutionContext.cs.

RestoreFlow()

static void System.Threading.ExecutionContext.RestoreFlow ( )

static

Restores the flow of the execution context across asynchronous threads.

Exceptions

T:System.InvalidOperationException

The context flow cannot be restored because it is not being suppressed.

Definition at line 663 of file ExecutionContext.cs.

Run()

static void System.Threading.ExecutionContext.Run ( ExecutionContext  executionContext, ContextCallback  callback, object  state  )

static

Runs a method in a specified execution context on the current thread.

Parameters

executionContext	The T:System.Threading.ExecutionContext to set.
callback	A T:System.Threading.ContextCallback delegate that represents the method to be run in the provided execution context.
state	The object to pass to the callback method.

Exceptions

T:System.InvalidOperationException

executionContext is null.-or- executionContext was not acquired through a capture operation. -or- executionContext has already been used as the argument to a M:System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext,System.Threading.ContextCallback,System.Object) call.

Definition at line 468 of file ExecutionContext.cs.

SuppressFlow()

static AsyncFlowControl System.Threading.ExecutionContext.SuppressFlow ( )

static

Suppresses the flow of the execution context across asynchronous threads.

Returns

An T:System.Threading.AsyncFlowControl structure for restoring the flow.

Exceptions

T:System.InvalidOperationException

The context flow is already suppressed.
