Begins an asynchronous wait-for-a-message-to-arrive operation that has a specified time out and state object associated with it.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
IAsyncResult BeginWaitForMessage( TimeSpan timeout, AsyncCallback callback, Object state )
- Type: System.TimeSpan
The Timespan that specifies the interval of time to wait for a message to become available.
- Type: System.AsyncCallback
The AsyncCallback delegate that receives the notification of the asynchronous operation completion.
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous operation.
Use the asynchronous method if you need the application processing to continue without waiting for the message to arrive. Use the synchronous WaitForMessage(TimeSpan) method when it is acceptable for the current thread to be blocked while it waits for a message to arrive in the queue. The thread is blocked up to the specified timeout.
This method receives notification, through a callback, of the identity of the event handler for the operation. The operation is not complete until either a message becomes available in the channel or the time out occurs.Notes to Implementers:
The operation returns false if the specified timeout is exceeded, not a timeout exception.
