消息持久化

		//...
      //4. 申明队列(指定durable:true,告知rabbitmq对消息进行持久化)
      channel.QueueDeclare(queue: "hellooo", durable: true, exclusive: false, autoDelete: false, arguments: null);
      //将消息标记为持久性 - 将IBasicProperties.SetPersistent设置为true
      var properties = channel.CreateBasicProperties();
      properties.Persistent = true;
      //5. 构建byte消息数据包
      string message = args.Length > 0 ? args[0] : "Hello RabbitMQ!";
      var body = Encoding.UTF8.GetBytes(message);
      //6. 发送数据包(指定basicProperties)
      channel.BasicPublish(exchange: "", routingKey: "hello", basicProperties: properties, body: body);
      //6. 发送数据包
      channel.BasicPublish(exchange: "", routingKey: "hello", basicProperties: null, body: body);
      Console.WriteLine(" [x] Sent {0}", message);
