I want to lock the accessing of current operating user, as if the user
clicked on Start → pointed to shutdown → click on LOCK
How to do that in C#?

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();
