開發環境&工具： VS2017 RabbitMq Erlang運行環境

先安裝Erlang運行環境然後再安裝RabbitMq

安裝和配置就不說了

默認安裝路徑：C:\Program Files\RabbitMQ Server，在rabbitmq_server-3.6.11\sbin文件夾下有bat文件

默認配置文件路徑： C:\Users\wangshibang\AppData\Roaming\RabbitMQ\rabbitmq.config

下面直接說代碼

客戶端Client把發送的消息儲存到RabbitMq中，服務器開啟的時候會從Rabbitmq中讀取儲存的消息

Clinet端代碼（記得添加 RabbitMQ.Client的Nuget包）

最後還有類庫的兩個類

 2 using System.Collections.Generic;
 3 using System.Linq;

 7 namespace RabbitMqLib

12 
13         public static int MqPort { get; } = 5672;
14 
15         public static string MqPwd { get; } = "guest";
16 
17         public static string MqUserName { get; } = "guest";
18     }
19 }

 5         public string Name { get; set; }
 6 
 7         public string Code { get; set; }
