AsyncFlowControl Structure

Provides the functionality to restore the migration, or flow, of the execution context between threads.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public struct AsyncFlowControl : IDisposable

The AsyncFlowControl type exposes the following members.

Public methodDisposeReleases all resources used by the current instance of the AsyncFlowControl class.
Public methodEquals(AsyncFlowControl)Determines whether the specified AsyncFlowControl structure is equal to the current AsyncFlowControl structure.
Public methodEquals(Object)Determines whether the specified object is equal to the current AsyncFlowControl structure. (Overrides ValueType.Equals(Object).)
Public methodGetHashCodeGets a hash code for the current AsyncFlowControl structure. (Overrides ValueType.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)
Public methodUndoRestores the flow of the execution context between threads.

Public operatorStatic memberEqualityCompares two AsyncFlowControl structures to determine whether they are equal.
Public operatorStatic memberInequalityCompares two AsyncFlowControl structures to determine whether they are not equal.

An execution context contains all execution-related information for a logical thread. The flow of the execution context to other threads can be prevented by using the ExecutionContext.SuppressFlow method, which returns an AsyncFlowControl structure. The Undo method of the returned AsyncFlowControl structure can be used to undo the flow suppression. The AsyncFlowControl structure must be used on the same thread on which it was created.
