C#实现定时关机小应用

C# 定时关机小应用(Winform)，供大家参考，具体内容如下

一、简述

记--使用winform实现的定时关机小应用。通过执行cmd命令实现的。(Visual Studio 2010旗舰版)

例子打包：链接

二、效果

三、工程结构及布局视图

四、源文件

五、总结

1、cmd关机相关命令

取消任务命令：shutdown -a
重启命令：shutdown -r -t sec  （于sec秒后重启）
关机命令：shutdown -s -t sec  （于sec秒后关机）
          at 23:00 shutdown -s  (在23:00执行shutdown -s，即在23:00关机。)
          at 某个时间 执行某个动作/应用  (win7测试管理员权限)

取消at计划（1是ID）

2、更改应用图标

3、窗体设置为无边框样式之后，就拖动不了了。可以通过监听鼠标动作，在窗体范围内，窗体跟随鼠标的移动。对于贴边其实就是设置窗体的位置。

4、调用第三方程序

Process process = new Process()//创建进程
process.StartInfo.FileName = exePath;//exePath:调用程序的路径
process.Start();//开始调用执行
process.WaitForExit();//等待退出
process.Close();//关闭进程
