Since JMS allocates some resources on behalf of a
IMessageConsumer outside the .NET CLR, clients should Close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.
There is no need to close a message consumer if the consumer's parent session or connection is closed, or if its parent context has been closed with CloseAll.
This call blocks until a
Receive or message listener in progress has completed. A blocked message consumer
Receive call returns null when this message consumer is closed.
|MessageException||if JMS fails to Close the consumer due to some internal error.|
