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
