比如你的电脑要在22:00关机，可以选择“开始→运行”，输入“at 22:00 Shutdown -s”，

java :

import java.io.IOException;

public class CtrWDS {

    private static CtrWDS ourInstance = null;

    private CtrWDS() {
    }

    public static CtrWDS getInstance() {
        if (ourInstance == null) {
            ourInstance = new CtrWDS();
        }
        return ourInstance;
    }

    public void exec(String cmd) {
        try {
            Runtime.getRuntime().exec(cmd);
        }
        catch (IOException e) {
            System.out.println("执行失败");        
        }
    }

    public void shutdown() {
        exec("shutdown -S ");
    }

    public void restart() {
        exec("shutdown -R ");
    }

    public void logout() {
        exec("shutdown -L ");
    }

    public static void main(String[] str) {
        if (str.length == 0) {
            System.out.println("-----------------------\n" +
                    "关机  -s\n" +
                    "重起  -r\n" +
                    "注销  -l\n" +
                    "-----------------------\n");
        }
        else{
           try{
               Thread.currentThread().sleep(10000L);
            }
            catch(Exception e){
               CtrWDS.getInstance().exec(str[0]);
            }
         }

    }

}

上面的大哥,但是我不懂JAVA呀,我想自己做一个,并不是利用系统关机.我想有C#做,你能不能提供源程序?
谢了

有简单的为什么不用?

但是我不懂JAVA,我现在想用C#做一个自己玩玩呀,学习呀.你说是不是?可以帮我不?
