RequestContext.BeginReply Method (Message, TimeSpan, AsyncCallback, Object)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
When overridden in a derived class, begins an asynchronous operation to reply to the request associated with the current context within a specified interval of time.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
public abstract IAsyncResult BeginReply( Message message, TimeSpan timeout, AsyncCallback callback, Object state )
Parameters
- message
- Type: System.ServiceModel.Channels.Message
The incoming Message that contains the request.
- timeout
- Type: System.TimeSpan
The TimeSpan that specifies the interval of time to wait for the reply to an available request.
- callback
- Type: System.AsyncCallback
The AsyncCallback delegate that receives the notification of the asynchronous reply operation completion.
- state
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous reply operation.
Return Value
Type: System.IAsyncResultThe IAsyncResult that references the asynchronous reply operation.
Use the asynchronous BeginReply method to allow the application processing to continue without waiting for the request to complete.
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 ImplementersThe operation throws a TimeoutException if the specified timeout is exceeded before it completes.
