MessageEnumerator.MoveNext Method (TimeSpan)
Advances the enumerator to the next message in the queue. If the enumerator is positioned at the end of the queue, MoveNext waits until a message is available or the given timeout expires.
Assembly: System.Messaging (in System.Messaging.dll)
Return ValueType: System.Boolean
true if the enumerator successfully advanced to the next message; false if the enumerator has reached the end of the queue and a message does not become available within the time specified by the timeout parameter.
This overload waits if there is no message in the queue or if the cursor has reached the end of the queue. If a message is not currently available because the queue is empty or because you have moved beyond the last element in the collection, MoveNext waits the specified timeout.
If the cursor is already at the end of the queue, MoveNext only returns true if the new message arrives within the specified time interval, has lower priority than all messages currently in the queue and is placed at the end of the queue. An overload with no parameter returns immediately if no further messages are in the queue.
Upon creation, an enumerator is conceptually positioned before the first message of the enumeration, and the first call to MoveNext brings the first message of the enumeration into view.
