从Azure Servicebus / IotHub

Question

我想经常检查azure servicebus / iothub的消息。但是，当我这样做时，我收到以下错误

＆＃34;类型＆＃39; Amqp.AmqpException＆＃39;的例外情况发生在mscorlib.dll但未在用户代码中处理 附加信息：操作＆＃39;接收＆＃39;在州：结束时无效。＆＃34;

我应该如何实现不断提取消息和/或解决此错误？

var connection = new Connection(address);
var session = new Session(connection);
var entity = Fx.Format("/devices/{0}/messages/deviceBound", _deviceId);

var receiveLink = new ReceiverLink(session, "receive-link", entity);
while (true)
{
    await Task.Delay(1000);

    var message = await receiveLink.ReceiveAsync();
    if (message == null) continue;
    //else do things with message
 }
