MessageQueue.Send Method (Object, String)
Sends an object to the non-transactional queue referenced by this MessageQueue and specifies a label for the message.
Assembly: System.Messaging (in System.Messaging.dll)
Use this overload to send a message that contains the obj parameter to the queue referenced by the MessageQueue. With this overload, you can specify the string label that identifies the message. The object you send to the queue can be a Message, a structure, a data object, or any managed object. If you send any object other than a Message, the object is serialized and inserted into the body of the message.
The message label is distinct from the message queue label, but both are application-dependent and have no inherit meaning to Message Queuing.
If you use this overload to send a message to a transactional queue, the message will be sent to the dead-letter queue. If you want the message to be part of a transaction that contains other messages, use an overload that takes a MessageQueueTransaction or MessageQueueTransactionType as a parameter.
The Path property for this MessageQueue instance must be specified before you send the message. If you do not set the Formatter property before calling Send(Object), the formatter defaults to the XmlMessageFormatter.
The DefaultPropertiesToSend property applies to any object other than a Message. If you specify, for example, a label or a priority using the DefaultPropertiesToSend member, these values apply to any message that contains an object that is not of type Message when your application sends it to the queue. When sending a Message, the property values set for the Message take precedence over DefaultPropertiesToSend and the message's Message.Formatter property takes precedence over the queue's MessageQueue.Formatter property.
