How to use C# to get the login name of the windows?

Hi,
you could use the following code for the same.

System.Security.Principal.WindowsPrincipal wp = new
System.Security.Principal.WindowsPrincipal
(System.Security.Principal.WindowsIdentity.GetCurrent());

MessageBox.Show(wp.Identity.Name);

Here the messagebox displays the domain name alongwith the
user logged in(the UseriD). Using the ID, you could
validate the user.

System.Environment.UserName
