How to get current Windows Login Name in C# Web APP?

Question

How can I get the user name of Windows Login? I used these methods:

• Environment.UserName
• WindowsIdentity.GetCurrent().Name;

But, when I PUT this inside IIS server, it takes the name of the server, not my machine.

Try Page.User.Identity.Name. This should be what you're looking for. This property is derived from HttpContext and represents the logged in user security information for the current HTTP request.

If the result is null, then I would suspect that the IIS settings is not configured properly. Try the advice in the following links:
