        const string newOrderQueueName = "neworder-queue-sms";

​

​

var connection = connectionFactory.CreateConnection();

var channel = connection.CreateModel();

//设置服务质量

channel.BasicQos(0, 1, false);

//定义一个类型为Fanout的交换机

channel.ExchangeDeclare(exchangeName, ExchangeType.Fanout, true, false, null);

//定义一个队列,将用于存放顾客下的订单

channel.QueueDeclare(queue: newOrderQueueName, durable: true, exclusive: false, autoDelete: false, arguments: null);

//将队列绑定到交换机上

channel.QueueBind(newOrderQueueName, exchangeName, "2", null);

//定义消费者

var consumer = new EventingBasicConsumer(channel);

consumer.Received += (model, ea) =>

{

var body = ea.Body;

var message = Encoding.UTF8.GetString(body);

Console.WriteLine(" [x] 短信消费者,需要把订单信息通过短信通知给商家. 这是订单信息:{0}" , message);

channel.BasicAck(ea.DeliveryTag, false);

};

channel.BasicConsume(queue: newOrderQueueName, false, consumer: consumer);

​

Console.WriteLine(" Press [enter] to exit.");

Console.ReadLine();

}

}

}

​
- 需要将交换机类型设置为ExchangeType.Fanout
- 需要将队列绑定到我们定义的fanout交换机上

​
### 另外的实验
​
- 忽略routingKey的实验，可以看到fanout交换机忽略了routingKey
​
```csharp
#发送
channel.BasicPublish(exchangeName, routingKey: "1", basicProperties: null, body: body);
​
#消费
channel.QueueBind(newOrderQueueName, exchangeName, "2", null);
channel.QueueBind(newOrderQueueName, exchangeName, "3", null);
