操作系统提供了关机控制的api函数

用ＡＰＩ好些，用ＤＯＳ命令如果系统没那命令就不可以了，

C# code

   private void button1_Click(object sender, EventArgs e)//关机
        {
            Process process = new Process();
            process.StartInfo.FileName = "shutdown.exe";
            process.StartInfo.Arguments = "-s -t 0";
            process.Start(); 

        }

        private void button2_Click(object sender, EventArgs e)//重启
        {
            Process process = new Process();
            process.StartInfo.FileName = "shutdown.exe";
            process.StartInfo.Arguments = "-r -t 0";
            process.Start();
