前言
最近項目要使用RabbitMQ，網上已經有很多優秀的文章了，百度百科對RabbitMQ闡述也非常明確，建議去看下，還有amqp協議。必須一提的是rabbitmq是由LShift提供的一個消息隊列協議（AMQP)的開源實現，由以高性能、健壯以及可伸縮性出名的Erlang寫成（因此也是繼承了這些優點）。
最近參考大神們的博客，自己做了一個RabbitMQ即時發消息的Demo。下面話不多說了，來一起看看詳細的介紹吧。
步驟如下：
1.使用VS的NuGet安裝包管理工具安裝RabbitMQ.Client:
2.生產者端代碼：

4.程序結果：
注：在第一步之前，你需要安裝RabbitMQ客戶端，可從http://www.rabbitmq.com/download.html下載，
但是RabbitMQ又是依賴于Erlang OTP平臺，所以，安裝RabbitMQ之前，需要先從http://www.erlang.org/download.html下載安裝erlang
