实现ＸＰ系统的开关机？？？

用c#代码怎么实现ＸＰ系统的开关机？？？

[我在深圳搬砖-Justin]

需要调用API

using System.Runtime.InteropServices;//用来调用API函数

调用API的部分直接复制

[jinjazz]

如果有权限的话，直接用rundll32.exe调用系统命令就可以了

如果没有权限需要先用windows api函数提升关机权限

关机很简单。

定时开机怎么办？

顶哦

Process 一个 shutdown -s -t 0 就行了~~

开机呀楼主~~这个没想过，关机以后恐怕 .Net Runtime 就没了，要实现开机的话，起码需要一台服务器，做网络唤醒才行

调用API。网上搜

关机可以用这个，
System.diagnostics.process=new system.diagnostics.process();
myprocess.startinfo.filename="cmd.exe";
myprocess.startinfo.useshellexecute=false;
myprocess.startinfo.Redirectstandardlnput=true;
myprocess.startinfo.Redirectstandardoutput=true;
myprocess.startinfo.RedirectstandardError=true;
myprocess.startinfo.Createnowindow=true;
myprocess.start();
myprocess.standardlnput.writeline("shoutdown-s-t 0");


system.diagnostics.process.start("cmd.exe","shutdown-s-t%time%");
-s关机
-l注销
-r重启
-t+时间
shutdown+你要干什么+-t你要执行的时间
