RequestContext.BeginReply Method (Message, AsyncCallback, Object)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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)

Syntax

'Declaration
Public MustOverride Function BeginReply ( _
    message As Message, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult

public abstract IAsyncResult BeginReply(
    Message message,
    AsyncCallback callback,
    Object state
)

Parameters

  • state
    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.

Remarks

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.
