Begins an asynchronous operation to receive a message that has a specified time out and state object associated with it.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
IAsyncResult BeginTryReceive( 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 when you want the application processing to continue without waiting. Use the synchronous TryReceive(TimeSpan, Message) method when it is acceptable for the current thread to be blocked while it replies to the request message or until the timeout interval is exceeded.
The operation is not complete until either a message becomes available in the channel or the timeout occurs.
If you are not going to treat timeouts specially then just call BeginReceive, otherwise you lose error information.Notes to Implementers
The operation returns false from EndTryReceive(IAsyncResult, Message) if the specified timeout is exceeded.
