Built-in helper to parse User.Identity.Name into Domain\Username

Question

Is there any built-in utility or helper to parse HttpContext.Current.User.Identity.Name, e.g. domain\\user to get separately domain name if exists

Answer 1

Although not a .NET built-in, one can always P/Invoke to CredUIParseUserName. Here's a example of how to use it in .NET.

PS: It doesn't seem to handle the "dot", as in ".\username".
