RequestContext.BeginReply Method (Message, AsyncCallback, Object)


When overridden in a derived class, begins an asynchronous operation to reply to the request associated with the current context.

Namespace:   System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public abstract IAsyncResult BeginReply(
	Message message,
	AsyncCallback callback,
	object state


Type: System.ServiceModel.Channels.Message

The incoming Message that contains the request.

Type: System.AsyncCallback

The AsyncCallback delegate that receives the notification of the asynchronous reply operation completion.

Type: System.Object

An object, specified by the application, that contains state information associated with the asynchronous reply operation.

Return Value

Type: System.IAsyncResult

The IAsyncResult that references the asynchronous reply operation.

Use the asynchronous BeginReply method when the application processing must continue without waiting. Use one of the synchronous Reply methods when it is acceptable for the current thread to be blocked while it replies to the request message or until the time-out interval is exceeded.

This method receives notification, through a callback, of the identity of the event handler for the operation. The operation is not complete until either the reply is sent or the time-out occurs.

Notes to Implementers:

The operation throws a TimeoutException if the specified timeout is exceeded before it completes.
