将消息从Windows服务传递到Windows窗体应用 [英] Pass message from windows service to a windows form app

问题描述

你好！
我正在开发一个Windows窗体应用程序，该应用程序需要在线显示Windows服务处理的信息.换句话说，要将消息从Windows服务传递到Windows窗体应用程序.

Hello!
I am developing a windows form application that need to show information processed by a windows service online. In other words, to pass messages from the windows service to the windows form application.
How can i do that using wcf?

推荐答案

这个问题太笼统了.它主要取决于Windows服务以及WCF的托管方式.最简单的情况是由服务自行托管.

您需要从头开始:
http://msdn.microsoft.com/en-us/library/dd456779.aspx [ ^ ]
http://msdn.microsoft.com/en-us/library/ms731067.aspx [ ^ ]
http://msdn.microsoft.com/en-us/library/ms731758.aspx [ ^ ]

我在这里看到了一个很好的CodeProject示例…:简单的WCF托管和使用 [来自同一端口号的多个客户端 [

This Question is too general. It mostly depends on the Windows Service and on how WCF is hosted. Most simple case is when it is self-hosted by the Service.

You need to start from the very beginning:
http://msdn.microsoft.com/en-us/library/dd456779.aspx[^]
http://msdn.microsoft.com/en-us/library/ms731067.aspx[^]
http://msdn.microsoft.com/en-us/library/ms731758.aspx[^]

I saw a good CodeProject sample… here: Simple WCF Hosting and Consuming[^].


To answer the follow-up Question: sending data from Service to client goes beyond the client-server paradigm and may mean some kind of published-subscriber schema.
Please also take a look at my Answer to this Question:
Multple clients from same port Number[^].
Unfortunately, in that page we discussed much lower-level networking (however, who knows, maybe it will suit you as well as this approach is more flexible and not too hard to use). At the same time, I describe a skeleton of the application with the threading schema, which is the most important key to such designs.

Using the approach outlind in the articles you should be able to create applcations that will be able to receive notifications from the service :)
