服务器和客户端应用程序之间的推送通知机制 [英] Push Notification mechanism between a server and a client app

问题描述

我正在使用 C# 开发桌面应用程序，该应用程序通过 WCF Web 服务与服务器进行通信.它应该是一种同步应用程序.这意味着当我对客户端应用程序进行一些更改时，我也应该立即更新服务器(这很容易使用服务调用)，但也应该提供这种机制，反之亦然，服务器上的更改必须立即应用于多个客户端.我知道我可以对我的服务器进行轮询，但这对我来说并不整洁，而且我也听说过双工服务，但我不确定是否可以使用它来实现这种机制.

I am developping a desktop application using C#, which communicates with a server over a WCF Web Service. It is supposed to be a kind of synchronization application. Meaning that when I make some changes on client app I should immediately update the server too(this is easy using service calls), but also this mechanism should be provided vice versa, a change on server must immediately be applied on several clients. I know I can make polling to my server but this doesn't look neat to me, and also I've heard of duplex services, but I'm not sure if I can use it to implement this mechanism.

我想就这个问题征求一些建议.提前致谢.

I am asking for some suggestions over this issue. Thanks in advance.

推荐答案

您需要实现发布和订阅设计.在 WCF 中，您可以使用 net-tcp 协议连接双工客户端和服务器.

You need to implement a publish and subscribe design. In WCF you could use net-tcp protocol to connect in duplex clients and server.
