Answer 1

http://jessn.blogspot.com/2009/05/lock-my-computer-programatically-in-c.html This article says it best:

A much better design that isn't hard coded to your windows system paths, etc:

using System.Runtime.InteropServices;

[DllImport("user32.dll")] public static extern void LockWorkStation();

Then just call LockWorkStation();

Answer 2

 System.Diagnostics.Process.Start("shutdown.exe -l");





      it will LOG OFF your computer and now if the account has secure with some password then windows will ask for password otherwise not.
