c# rabbitmq 简单收发消息的示例代码

发布消息：（生产者）

   /// <summary>
    /// 发送消息
    /// </summary>
    /// <param name="queue">队列名</param>
    /// <param name="message">消息内容</param>
    private static void PublishInfo(string queue, string message)
    {
      try
      {
        var factory = new ConnectionFactory();
        factory.HostName = "localhost";//RabbitMQ服务在本地运行
        factory.UserName = "guest";//用户名
        factory.Password = "guest";//密码

        using (var connection = factory.CreateConnection())
        {
          using (var channel = connection.CreateModel())
          {
            bool durable = true;//将消息标记为持久性
            channel.QueueDeclare(queue, durable, false, false, null);

            IBasicProperties properties = channel.CreateBasicProperties();
            properties.DeliveryMode = 2;

            var body = Encoding.UTF8.GetBytes(message);
            channel.BasicPublish("", queue, properties, body); //开始传递

          }
        }
      }
      catch (System.Exception ex)
      {
        Console.WriteLine(ex.ToString());
      }
      Console.ReadLine();
    }

使用：

PublishInfo("test", "222222222222");

 点击test进入队列内部：

消费消息：

方法一：旧版可用

 private static void ConsumeInfo(string queue)
    {
      try
      {
        var factory = new ConnectionFactory();
        factory.HostName = "localhost";//RabbitMQ服务在本地运行
        factory.UserName = "guest";//用户名
        factory.Password = "guest";//密码

        using (var connection = factory.CreateConnection())
        {
          using (var channel = connection.CreateModel())
          {
            //bool durable = true;//将消息标记为持久性
            //channel.QueueDeclare("sljcgx:finish-queue", durable, false, false, null);//声明队列，队列不存在则创建该队列

            //设置prefetchCount : 1来告知RabbitMQ，在未收到消费端的消息确认时，不再分发消息，也就确保了当消费端处于忙碌状态时，不再分配任务。
            channel.BasicQos(prefetchSize: 0, prefetchCount: 1, global: false);
            var consumer = new QueueingBasicConsumer(channel);
           
            //false为手动确认，获取消息后需要添加 channel.BasicAck(ea.DeliveryTag, false)确认
            //true则为自动确认，不需要这行代码
            channel.BasicConsume(queue, false, consumer);

            while (true)
            {
              try
              {
                var ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue();//阻塞函数，获取队列中的消息
                var bodyReceive = ea.Body;
                string message = Encoding.UTF8.GetString(bodyReceive);
                Console.WriteLine(message);
                channel.BasicAck(ea.DeliveryTag, false);// 消息确认信号，确认后该消息将从队列里移除
              }
              catch (System.Exception ex)
              {
                
                Console.WriteLine(ex.Message);
              }
            }
          }

        }
      }
      catch (System.Exception ex)
      {
        Console.WriteLine(ex.ToString());
      }
      Console.ReadLine();
    }

方法二：（通用）

   private static void ConsumeInfo2(string queue)
    {
      try
      {
        var factory = new ConnectionFactory();
        factory.HostName = "localhost";//RabbitMQ服务在本地运行
        factory.UserName = "guest";//用户名
        factory.Password = "guest";//密码
        var connection = factory.CreateConnection();
        var channel = connection.CreateModel();
        channel.QueueDeclare(queue, true, false, false, null);//声明队列，队列不存在则创建该队列
        channel.BasicQos(0, 1, false);//公平分发、同一时间只处理一个消息。

        var consumer = new EventingBasicConsumer(channel); //消费者（指定消息通道）该事件在接收到消息时触发
        consumer.Received += (sender, e) =>
        {
          byte[] body = e.Body.ToArray();  //消息字节数组
          string message = Encoding.UTF8.GetString(body); //消息内容

          Console.WriteLine(message);
          channel.BasicAck(e.DeliveryTag, false);    //手工确认

        };
        channel.BasicConsume(queue, false, consumer);  //消费消息（在当前通道中监听 queue 队列，并进行消费）
        Console.ReadLine();
        connection.Close();
        channel.Close();
      }
      catch (System.Exception ex)
      {
        Console.WriteLine(ex.ToString());
      }
    }
