Begins an asynchronous request operation that has a specified time out and state object associated with it.
public:
IAsyncResult ^ BeginWaitForRequest(TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);public IAsyncResult BeginWaitForRequest (TimeSpan timeout, AsyncCallback callback, object state);abstract member BeginWaitForRequest : TimeSpan * AsyncCallback * obj -> IAsyncResultPublic Function BeginWaitForRequest (timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- timeout
- TimeSpan
The TimeSpan that specifies the interval of time to wait for the reception of an available request.
- callback
- AsyncCallback
The AsyncCallback delegate that receives the notification of the asynchronous receive that a request operation completes.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous receive of a request operation.
Returns
The IAsyncResult that references the asynchronous operation to wait for a request message to arrive.
Examples
The following code illustrates how to implement this method:
public IAsyncResult BeginWaitForRequest(TimeSpan timeout, AsyncCallback callback, object state)
{
return this.InnerChannel.BeginWaitForRequest(timeout, callback, state);
}
Remarks
Use the synchronous WaitForRequest(TimeSpan) method when it is acceptable for the current thread to be blocked while it waits for a request 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 request message becomes available in the channel or the time out occurs.
Notes to Implementers
The operation returns false if the specified timeout is exceeded.
