How to shut down with C #, Process.Start ("shutdown") not working in Windows XP

Question

After some of you discuss how to reset my computer and or turn it off from C #, I found this explanation on how to do it:

ManagementBaseObject outParameters = null;
ManagementClass sysOS = new ManagementClass("Win32_OperatingSystem");
sysOS.Get();

// Enables required security privilege.
sysOS.Scope.Options.EnablePrivileges = true;

// Get our in parameters
ManagementBaseObject inParameters = sysOS.GetMethodParameters("Win32Shutdown");

// Pass the flag of 0 = System Shutdown
inParameters["Flags"] = "1"; //shut down.
inParameters["Reserved"] = "0";
foreach (ManagementObject manObj in sysOS.GetInstances())
{
    outParameters = manObj.InvokeMethod("Win32Shutdown", inParameters, null);
}

This worked on Windows 7, but not on a Windows XP window, I tried it. Therefore, I realized that it allows me to switch to a simpler solution:

Process.Start("shutdown", "/s /t 00");

    }
    else
    {
        // Write out the logs.
        List<String> logs = LogUtil.getLog(); // mic.getLog();

        // Create a writer and open the file
        TextWriter tw = new StreamWriter(userAppData + "\\logTMC.txt", true);

        // Write a line of text to the file
        tw.WriteLine("----- " + DateTime.Now + " ------");
        foreach (String log in logs)
        {
            tw.WriteLine(log);
        }

        // Close the stream
        tw.Close();
    }
}

Answer 3

I believe that is correct. You just need to change the command:

shutdown.exe -s -t 00

It works on my windows box (from cmd).
