C# 代码实现 Windows服务：计时器=>简单实现

 

 

 

输入项目名称，选择框架直接生成项目

 

 

 

点击添加

 

 

 

选择属性后更换

 

 

 

将USER 改为 LOCALSYSTEM

 

 

 

 

可以自己更改serviceInstaller1 和servicename

SeriviceName:就是你等下装到系统里面的服务名称

在更改的页面右击查看代码或者F7

 

 

 

继承serviceBase,重写onstart(),onstop()方法

这两个方法记录服务启动和停止，在这两个方法里面增加写日志的方法，当服务启动停止可以直接查看日志

 

 

 

两种写入的方法，都很扣脚

复制C:\Windows\Microsoft.NET\Framework\v4.0.30319 下的InstallUtil.exe到生成的文件夹下

CMD先进入刚刚所在的文件夹

CMD管理员身份运行刚刚VS 生成的目录

 

 

剩下的今天来不及了，以后再记录吧
