从我的WCF应用程序向客户端应用程序发送一些消息 [英] Send some messages to client application from my WCF application

问题描述

我正在开发WCF服务。一旦客户提出请求，我的服务必须发送一些消息，如任务1完成，任务2完成反之亦然......最后需要发送响应。



Up到现在为止我完全回应了客户。但我希望在客户等待最终回复的同时向客户提供处理信息。



使用的技术：



客户：DOTNET应用程序V3.5

服务器：DOTNET WCF服务。

绑定：流式请求绑定。



如果我无法解释清楚，我很抱歉。请帮我解决这个问题。

解决方案

实际上你必须从服务器向客户端发送事件。通过WCF，Microsoft可以将这种服务称为双工服务。使用该搜索词，您可以在网上找到更详细的帮助。

I am developing WCF Service. Once the client gives request, my service has to send some messages like Task 1 completed, Task 2 completed vise versa... and finally need to send response.

Up to now I am giving response to client perfectly. But I want to give processing information to the client while the client waiting for final response.

Technology used:

Client : DOTNET Application V3.5
Server : DOTNET WCF Services.
Bindings : Streamed request binding.

I am sorry if I was not able to explain clearly. Please help me regarding this.

解决方案

Actually you have to send events from the server to the client. It is possible with WCF, Microsoft uses to call such a service a "duplex service". With that search term, you'll find some more detailed help on the web.
