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：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using RabbitMQ.Client;namespace RabbitMQ.Producter{ class Program { /// <summary> /// 连接配置 /// </summary> private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory() {  HostName="localhost",  UserName = "guest",  Password = "guest",  Port = 5672,  //VirtualHost = "JentVirtualHost" }; /// <summary> /// 路由名称 /// </summary> const string ExchangeName = "Jent.Exchange"; /// <summary> /// 队列名称 /// </summary> const string QueueName = "Jent.Queue"; static void Main(string[] args) {  DirectExchangeSendMsg();  Console.WriteLine("按任意键退出程序！");  Console.ReadKey(); } /// <summary> /// 单点精确路由模式 /// </summary> private static void DirectExchangeSendMsg() {  using (IConnection conn = rabbitMqFactory.CreateConnection())  {  using (IModel channel = conn.CreateModel())  {   channel.ExchangeDeclare(ExchangeName, "direct", durable: true, autoDelete: false, arguments: null);   channel.QueueDeclare(QueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);   channel.QueueBind(QueueName, ExchangeName, routingKey: QueueName);   var props = channel.CreateBasicProperties();   props.Persistent = true;   Console.WriteLine("请输入需要发送的消息:");   string vadata = Console.ReadLine();   while (vadata != "exit")   {   var msgBody = Encoding.UTF8.GetBytes(vadata);   channel.BasicPublish(exchange: ExchangeName, routingKey: QueueName, basicProperties: props, body: msgBody);   Console.WriteLine(string.Format("发送时间：{0}，发送完毕，输入exit退出消息发送", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")));   vadata = Console.ReadLine();   }  }  } } }}

3.消费者端代码：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using RabbitMQ.Client;namespace RabbitMQ.Consumer{ class Program { /// <summary> /// 连接配置 /// </summary> private static readonly ConnectionFactory rabbitMqFactory = new ConnectionFactory() {  HostName = "127.0.0.1",  UserName = "guest",  Password = "guest",  Port = 5672,  //VirtualHost = "JentVirtualHost" }; /// <summary> /// 路由名称 /// </summary> const string ExchangeName = "Jent.Exchange"; /// <summary> /// 队列名称 /// </summary> const string QueueName = "Jent.Queue"; static void Main(string[] args) {  DirectAcceptExchange();  Console.WriteLine("输入任意值退出程序！");  Console.ReadKey(); } private static void DirectAcceptExchange() {  using (IConnection conn = rabbitMqFactory.CreateConnection())  {  using (IModel channel = conn.CreateModel())  {   channel.ExchangeDeclare(ExchangeName, "direct", durable: true, autoDelete: false, arguments: null);   channel.QueueDeclare(QueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);   channel.QueueBind(QueueName, ExchangeName, routingKey: QueueName);   while (true)   {   BasicGetResult msgResponse = channel.BasicGet(QueueName, autoAck: false);   if (msgResponse != null)   {    var msgBody = Encoding.UTF8.GetString(msgResponse.Body);    Console.WriteLine(string.Format("接收时间：{0}，消息内容：{1}", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), msgBody));   }   //System.Threading.Thread.Sleep(TimeSpan.FromSeconds(1));   }  }  } } }}

4.程序结果：
