Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
Exceptions associated with the MessageQueueException class are generated by internal errors within Message Queuing that should be dealt with through your code.
Every exception consists of an error code and a text string that describes the source of the error. See the MessageQueueErrorCode class for a list of these error codes and their descriptions.
