        var channel = connection.CreateModel();

​
//设置服务质量
channel.BasicQos(0, 1, false);
​
//定义一个类型为Headers的交换机
channel.ExchangeDeclare(exchangeName, ExchangeType.Headers, true, false, null);
​
​
//定义一个队列,将用于存放用户的信息
channel.QueueDeclare(queue: queueName, durable: true, exclusive: false, autoDelete: false, arguments: null);
​
​
//将队列绑定到交换机上
channel.QueueBind(queueName, exchangeName, string.Empty, new Dictionary<string, object>()
{
{"x-match", "any"},
{"username", "tangxiaobing"}
});
​
​
//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("用户名匹配,验证通过,信息:{0}", message);
channel.BasicAck(ea.DeliveryTag, false);
};
channel.BasicConsume(queue: queueName, false, consumer: consumer);
​
​
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
}
}
}
​

- 在将队列绑定到交互机时,需要注意设置配置规则参数arguments
```csharp
    void QueueBind(
      string queue,
      string exchange,
      string routingKey,
      IDictionary<string, object> arguments);

• x-match 取值为 any,表示arguments参数中指定的header只要有任意一个匹配,就会被路由到队列.
