MessageQueueTransaction Class

Provides a Message Queuing internal transaction.

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

public class MessageQueueTransaction : IDisposable

To send or receive a message as part of a transaction, you can use the MessageQueueTransaction class to create a transaction and pass it to an overload of the MessageQueue.Send method or the MessageQueue.Receive method that takes a transaction parameter. Messages sent as part of a transaction must be sent to transactional queues. Messages received from transactional queues must be received using a specified transaction.

In addition to the Receive method, you can receive messages with a specified identifier or specified correlation identifier. See the ReceiveById and ReceiveByCorrelationId methods for more information about selectively receiving messages from transactional queues.

Messages sent to transactional queues are removed if the transaction is committed. Similarly, messages received from transactional queues are returned to the queue if the transaction is rolled back.

If you instantiate a MessageQueueTransaction and pass it to an applicable overload of the Send method or Receive method to send a message to a non-transactional queue or receive a message from a non-transactional queue, the method throws an exception that indicates "Wrong Transaction Usage."

[Visual Basic]

MessageQueueTransaction is threading apartment aware, so if your apartment state is STA, you cannot use the transaction in multiple threads. Visual Basic sets the state of the main thread to STA, so you must apply the MTAThreadAttribute in the Main subroutine. Otherwise, sending a transactional message using another thread throws a MessageQueueException exception. You apply the MTAThreadAttribute by using the following fragment.

<System.MTAThreadAttribute>
 public sub Main()

System.Object
  System.Messaging.MessageQueueTransaction

This type is thread safe.
