C #, using the DOS command to close the currently running programs and restart

         In C # can be used to perform many operations invoked Dos command Pocess.Start, and very convenient. For example closes the current application, restart the computer and so on.

        Here are a few commonly used commands:

// restart the computer command

private void RestartPC()

{

        // restart the computer commands issued
        Process.Start ( "the Shutdown.exe", "-r");
        // close all related processes
        Process.GetCurrentProcess () Kill ().;

}

// Turn off the computer command

private void ShutDownPC()

{

        // restart the computer commands issued
        Process.Start ( "the Shutdown.exe");
        // close all related processes
        Process.GetCurrentProcess () Kill ().;

}

// Turn off the computer overloaded function, you can set the countdown

        public static void ShutDownPC(string time)
        {
            string s = "-s -t " + time;
            Process.Start("shutdown.exe", s);

        }

        //logout

        public static void LogOff()
        {
            Process.Start("shutdown.exe", "-l");
        }

         // Turn off the computer revoked

         public static void CancelShutDown()
        {
            Process.Start("shutdown.exe", "-a");
        }

// open an application, such as turning upgrade program

    /// <Summary>
    /// upgrade program start
    /// </ Summary>
    Private void StartUpdateSys ()
        {
        // Start upgrade
        Process [] = VAproc Process.GetProcessesByName ( "VersionAgent");
        IF (= VAproc.Length 0 =)
            {
            Process proc = new new Process ();
            proc.StartInfo.FileName = "VersionAgent.exe";
            proc.StartInfo.Arguments = "/ P1 / b38400 / fstock / of Mr";
            proc.StartInfo.WindowStyle = the System.Diagnostics .ProcessWindowStyle.Hidden;
            proc.Start ();
            }
        }
