C # implements a method for communicating with active MQ _c# tutorial

The example in this article describes how C # implements the method of communicating with active MQ. Share to everyone for your reference, specific as follows:

Content Summary:

Mainly in the form of source code describes how to use C # to implement the communication with active MQ. This article assumes that you have properly installed jdk1.6.x, understand active MQ and have a certain programming base.

Body:

The ultimate goal of a JMS program is to produce and consume messages that can be used by other programs, and the JMS message is a simple and flexible basic format that allows you to create messages that are not in the JMS format on different platforms.
The message consists of the header, the attributes, and the message body three parts.
Active MQ supports filtering mechanism, that is, the producer can set the properties of the message, which corresponds to the selector of the consumer, and only the selector of the consumer setting matches the properties of the message, and the message is sent to the consumer. Both topic and queue support Selector.
