Assembly: System.Messaging (in System.Messaging.dll)
identifies ongoing or completed asynchronous operations. The property contains data that helps determine which of several potential asynchronous operations to complete, and when passed to the event handler, enables EndPeek to access the message associated with the completed operation.
When you call BeginPeek, a IAsyncResult is returned immediately, even though a message, if one exists, has not yet been retrieved because the operation is not completed. The indicates the state of the asynchronous operation. BeginPeek creates the object, which is modified throughout the operation until EndPeek completes it.
