.NET 中使用 RabbitMQ

1. 新建一个发送消息的控制台工程 FirstRabbitMQSend

   using RabbitMQ.Client;
   using System;
   using System.Text;
   
   namespace FirstRabbitMQSend
   {
       class Program
       {
           // 交换器名
           const string EXCHANGE_NAME = "hello.exchange";
           // 队列名
           const string QUEUE_NAME = "hello.queue";
   
           static void Main(string args)
           {
               // 定义连接工厂
               var factory = new ConnectionFactory() {
                   HostName ="localhost",
                   UserName = "liujj",
                   Password = "AAA@111",
               };
               // 连接到 RabbitMQ
               using (var connection = factory.CreateConnection())
               {
                   // 获取信道
                   using (var channel  = connection.CreateModel())
                   {
                       // 声明交换器
                       channel.ExchangeDeclare(
                           exchange: EXCHANGE_NAME,
                           type: "direct",
                           durable: true);
                       // 声明队列
                       channel.QueueDeclare(
                           queue: QUEUE_NAME,
                           durable: true,
                           exclusive: false,
                           autoDelete: false,
                           arguments: null);
                       // 绑定交换器到队列
                       channel.QueueBind(
                           queue: QUEUE_NAME,
                           exchange: EXCHANGE_NAME,
                           routingKey: QUEUE_NAME);
                       // 创建消息
                       string message = "Hello, World!";
                       var body = Encoding.UTF8.GetBytes(message);
                       // 发布消息
                       channel.BasicPublish(
                           exchange: EXCHANGE_NAME,
                           routingKey: QUEUE_NAME,
                           basicProperties: null,
                           body: body);
                       Console.WriteLine("set {0}", message);
                   }
               }
           }
       }
   }

2. 新建一个接收的控制台工程 FirstRabbitMQReceive

   using RabbitMQ.Client;
   using RabbitMQ.Client.Events;
   using System;
   using System.Text;
   
   namespace FirstRabbitMQReceive
   {
       class Program
       {
           // 交换器名
           const string EXCHANGE_NAME = "hello.exchange";
           // 队列名
           const string QUEUE_NAME = "hello.queue";
   
           static void Main(string args)
           {
               // 定义连接工厂
               var factory = new ConnectionFactory()
               {
                   HostName = "localhost",
                   UserName = "liujj",
                   Password = "AAA@111",
               };
               // 连接到 RabbitMQ
               using (var connection = factory.CreateConnection())
               {
                   // 获得信道
                   using (var channel = connection.CreateModel())
                   {
                       // 声明交换器
                       channel.ExchangeDeclare(
                           exchange: EXCHANGE_NAME,
                           type: "direct",
                           durable: true);
                       // 声明队列
                       channel.QueueDeclare(
                           queue: QUEUE_NAME,
                           durable: true,
                           exclusive: false,
                           autoDelete: false,
                           arguments: null);
                       // 绑定交换器到队列
                       channel.QueueBind(
                           queue: QUEUE_NAME,
                           exchange: EXCHANGE_NAME,
                           routingKey: QUEUE_NAME);
                       // 声明消费者
                       var consumer = new QueueingBasicConsumer(channel);
                       // 订阅消费者
                       channel.BasicConsume(
                           queue: QUEUE_NAME,
                           noAck: true,
                           consumer: consumer);
                       Console.WriteLine("waiting for message.");
                       while (true)
                       {
                           // 消费消息
                           var ea = consumer.Queue.Dequeue() as BasicDeliverEventArgs;
                           var body = ea.Body;
                           var message = Encoding.UTF8.GetString(body);
                           Console.WriteLine("Received {0}", message);
                       }
                   }
               }
           }
       }
   }
