CWF框架之windowsService

我们在做应用的的时候经常会遇到定时运行或者端口监视等,这样我们需要开发一个程序长时间的运行并且随操作系统启动。

这个时候最佳选择我觉得上windows服务。当然在.net上开发一个服务上一件那么轻松的事情,但是会发现一个问题,在系统中

往往需要多个服务或者不可预知的情况给予扩展,这个时候需要重新编译开发完成的服务,然后卸载先前的服务,再安装最新的。

可能开始几个服务还不觉得怎么样,随着系统的升级和功能的健全重构是要命的,如果不卸载先前的服务重新安装新服务造成系统

资源的浪费也非常不划算,在统一管理上启动和停止服务也是个头痛的事情。

那么这里就采用了陈新老师的解决方案,把本身就上windows服务的服务做成一个可扩展的框架然后通过配置去扩展系统需要用到的服务

这样每次扩展就不需要重新卸载安装甚至不用重新编译程序,并且实现统一的启动停止操作。

按照我写博客的习惯基本不会有多少介绍,因为现在上上班时间。。。

那就继续看代码。

这样就OK了,是不是很简单,简单适用就好。那么每次需要服务就去app.config读取OK了。
