我正在尝试组装一个简单的 AppFabric 主题,从而使用 SessionId 发送和接收消息。代码不会中止,但 brokeredMessage 始终为空。这是代码:
// BTW, the topic already exists
var messagingFactory = MessagingFactory.Create(uri, credentials);
var topicClient = messagingFactory.CreateTopicClient(topicName);
var sender = topicClient.CreateSender();
var message = BrokeredMessage.CreateMessage("Top of the day!");
message.SessionId = "1";
sender.Send(message);
var subscription = topic.AddSubscription("1", new SubscriptionDescription { RequiresSession = true});
var mikeSubscriptionClient = messagingFactory.CreateSubscriptionClient(subscription);
var receiver = mikeSubscriptionClient.AcceptSessionReceiver("1");
BrokeredMessage brokeredMessage;
receiver.TryReceive(TimeSpan.FromMinutes(1), out brokeredMessage); // brokeredMessage always null
