C#远程关机代码

C#远程关机代码：

方法1

//按钮点击事件

private void button1_Click(object sender, EventArgs e)
        {
            //此处需要添加System.Management的引用
            ConnectionOptions op = new ConnectionOptions();
            //获取远程计算机的用户名
            op.Username = txtAdmin.Text.Trim();
            //获取远程计算机的密码
            op.Password = txtPassword.Text.Trim();

            ManagementScope scope = new ManagementScope("\\\\" + textBox1.Text + "\\root\\cimv2", op);

            scope.Connect();

            ObjectQuery oq = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
            ManagementObjectSearcher query = new ManagementObjectSearcher(scope, oq);

            ManagementObjectCollection queryCollection = query.Get();
            foreach (ManagementObject obj in queryCollection)
            {
                obj.InvokeMethod("ShutDown", null); //命令换成reboot就是重启
            }

        }

 方法2

ConnectionOptions options = new ConnectionOptions();
  
  options.Username = textBox2.Text; //用户名
  options.Password = textBox3.Text; //用户口令
  try
  {
   ManagementScope Conn = new ManagementScope("\\\\" + textBox1.Text + "[url=file://rootcimv2/]\\root\\cimv2[/url]", options);
   Conn.Connect();
   //确定WMI操作的内容
   ObjectQuery oq = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
   ManagementObjectSearcher query1 = new ManagementObjectSearcher(Conn, oq);
   //获取WMI操作内容
   ManagementObjectCollection queryCollection1 = query1.Get();
   //根据使用者选择执行相应的远程操作
   foreach (ManagementObject mo in queryCollection1)
   {
    string [ ] ss= { "" };
    
    if (comboBox1.Text == "重新启动")
     mo.InvokeMethod("Reboot", ss); //执行重启操作
    else if (comboBox1.Text == "远程关机")
     mo.InvokeMethod("Shutdown", ss); //执行远程关机
    else
     MessageBox.Show ("选择不正确的操作！", "错误！");
   }
  }
  catch(Exception ee)
  {
   MessageBox.Show("连接" + textBox1.Text + "出错，出错信息为：" + ee.Message ); //报错
  }
