MessageEnumerator.MoveNext Method

Advances the enumerator to the next message in the queue, if one is currently available.

Namespace:  System.Messaging
Assembly:  System.Messaging (in System.Messaging.dll)

public bool MoveNext()

Return Value

Type: System.Boolean
true if the enumerator was succesfully advanced to the next message; false if the enumerator has reached the end of the queue.

Implements

IEnumerator.MoveNext()

ExceptionCondition
MessageQueueException

An exception specific to Message Queuing was thrown.

This overload returns immediately if there is no message in the queue. There is another overload that waits a specified TimeSpan for a message to arrive.

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 returns false to the calling method.

Upon creation, an enumerator is conceptually positioned before the first message of the queue, and the first call to MoveNext brings the first message of the queue into view.
