MessageQueue.GetMessageEnumerator2 Method

Definition

Creates an enumerator object for all the messages in the queue.

public:
 System::Messaging::MessageEnumerator ^ GetMessageEnumerator2();
public System.Messaging.MessageEnumerator GetMessageEnumerator2 ();
member this.GetMessageEnumerator2 : unit -> System.Messaging.MessageEnumerator
Public Function GetMessageEnumerator2 () As MessageEnumerator

Returns

The MessageEnumerator holding the messages that are contained in the queue.

Remarks

GetMessageEnumerator2 creates a dynamic list of all the messages in a queue. You can remove from the queue the message at the enumerator's current position by calling RemoveCurrent for the MessageEnumerator that GetMessageEnumerator2 returns.

Because the cursor is associated with the dynamic list of messages in the queue, the enumeration reflects any modification you make to the messages in the queue, if the message is beyond the current cursor position. For example, the enumerator can automatically access a lower-priority message placed beyond the cursor's current position, but not a higher-priority message inserted before that position. However, you can reset the enumeration, thereby moving the cursor back to the beginning of the list, by calling Reset for the MessageEnumerator.

The order of the messages in the enumeration reflects their order in the queue, so higher-priority messages will appear before lower-priority ones.

If you want a static snapshot of the messages in the queue rather than a dynamic connection to them, call GetAllMessages. This method returns an array of Message objects, which represent the messages at the time the method was called.
