前言
最近项目要使用RabbitMQ，网上已经有很多优秀的文章了，百度百科对RabbitMQ阐述也非常明确，建议去看下，还有amqp协议。必须一提的是rabbitmq是由LShift提供的一个消息队列协议（AMQP)的开源实现，由以高性能、健壮以及可伸缩性出名的Erlang写成（因此也是继承了这些优点）。
最近参考大神们的博客，自己做了一个RabbitMQ即时发消息的Demo。下面话不多说了，来一起看看详细的介绍吧。
步骤如下：
1.使用VS的NuGet安装包管理工具安装RabbitMQ.Client:
2.生产者端代码：

4.程序结果：
注：在第一步之前，你需要安装RabbitMQ客户端，可从http://www.rabbitmq.com/download.html下载，
但是RabbitMQ又是依赖于Erlang OTP平台，所以，安装RabbitMQ之前，需要先从http://www.erlang.org/download.html下载安装erlang
