Question

I’m building a C# application, and I want to identify users by their username. For example, if I logged onto the domain mydomain as the user myusername I’d want to get the mydomain\myusername so I can identify the user.

How can I do this with C#?

Answer 1

It’s very simple indeed:

Environment.UserName

From the MSDN page:

The UserName property provides part of
the credentials associated with
computer domain names, as returned by
the UserDomainName property. This
information is typically represented
as DOMAIN\username.

This property can be used to identify
the current user to the system and
application for security or access
purposes. It can also be used to
customize a particular application for
each user.

You can also get the domain name using Environment.UserDomainName.
