有没有办法从服务器发送通知给客户以任何方式比WCF双工其他？请告诉所有选项。

推荐答案

我假设，因为你有问题，传入连接防火墙问题。

I am assuming because of firewall issues you have problems with an incoming connection.

在这种情况下，以解决该问题的常用方法是

In such a scenario a common way to solve the problem is.

1. 有从中使用服务请求的 A 也许 GetNextNotification
轮询服务器一个单独的线程
2. 在这方面应该有一个较高的超时时间。
3. 在服务器端时的 A 的处理方法不会返回，直到有一些服务器想要传达的客户端
4. 当 A 返回客户端处理的通知，并让另一个 A 的要求。

1. Have a separate thread from which you poll the server using the service request A maybe GetNextNotification
2. This connection should have a high timeout.
3. On the server side when A is processed the method doesn't return until there is something server wants to convey to the client
4. Once A returns the client processes the notification and makes another A request.
