How can I gets the user name of the person who is currently logged on to the Windows, because Environment.UserName return user2, but I want domain1\\user1.

Check out WindowsImpersonationContext on MSDN, I believe it has what you're looking for.

You can implement your own helper class if you like, then declare using([establish your context here]) and perform your activities within that code block that will be executed with that user context. Quite handy!

Note: If you decide to utilize using , be sure in the Dispose() method of your helper that you release the impersonation context so that everything cleans up nicely when your program leaves the using block.
