Get Windows Login and Logoff time in C# Windows application

Do this way

            label3.Text = CurrentUserLoggedInTime.Value.ToString()

i have use break point it is not going till that step it is executing till

 UserPrincipal uc = UserPrincipal.FindByIdentity(c, "Rashid");

This line takes time. You need to wait

the form is loaded and it dosent show anything in label3.text

The same thing is working fine for me in windows 7. Make sure you are not in a domain
