MessageQueueTask Class

Contains the methods and properties used by the Message Queue task. This class cannot be inherited.

Namespace:  Microsoft.SqlServer.Dts.Tasks.MessageQueueTask
Assembly:  Microsoft.SqlServer.MSMQTask (in Microsoft.SqlServer.MSMQTask.dll)

public sealed class MessageQueueTask : Task, 
	IDTSComponentPersist, IMessageQueueTask, IDTSBreakpointSite, IDTSSuspend

The Message Queue task class allows an object to send and receive messages to or from a queue of Message Queuing (also known as MSMQ). Participation in distributed transactions is allowed when running the Microsoft Distributed Transaction Coordinator (MSDTC). A single instance of a Message Queue task either sends one message to a specified queue or receives a single message from a specified queue, and also waits, if necessary, for the message to arrive. The following types of messages can be sent:

  • A string message, which is supplied as the value of a property.

  • A data file message, which is generated from the contents of a specified data file.

  • A variables message, which is generated from the names and values of one or more SQL Server Integration Services variables.

The enumeration MQMessageType determines which message format is used by a specific Message Queue task.

For more information, see Message Queue Task.

For the MessageQueueTask to work in either the API or in SSIS Designer, you must install SQL Server Integration Services. This feature will not work if only Business Intelligence Development Studio is installed.

Important noteImportant

When configuring the Message Queue task to send messages, you can use one of the encryption algorithms that are currently supported by the Message Queuing, RC2 and RC4, to encrypt the message. Both of these encryption algorithms are now considered cryptographically weak compared to newer algorithms, which Message Queuing does not yet support. Therefore, you should consider your cryptography needs carefully when sending messages using the Message Queue task.
