Get Windows Username in ASP.NET without System.Web

Question

I have a reporting dll that is used in ASP.NET (Windows Authentication) and winforms projects. Sometimes it needs the username so if it was running in ASP.NET it would use:

System.Web.HttpContext.Current.User.Identity.Name;

and in windows

WindowsIdentity.GetCurrent().Name

Now I am trying to move to .NET 4 Client Profile so I need to avoid the System.Web reference in the reporting dll. Is there an alternative way to get the Windows Username for when the dll is running in ASP.NET which won't use System.Web. The only way I can currently see to avoid System.Web is to pass the Username as a parameter which will be a pain to adjust for in every report.

Answer 1

Maybe you can use the CurrentPrincipal property of the Thread class:

using System.Threading;

string userName = Thread.CurrentPrincipal.Identity.Name;

Answer 2

You can use Environment.UserName which lives in System.

Answer 3

If Windows authentication is on this might work: Page.User.Identity.Name In my case, it does.

Answer 4

System.Web namespace is definitely available in an ASP.Net application. You can definitely make use of it. Apart from that, you will also have the Membership providers that you can use to validate or tell the current user name.

Answer 5

Using System.net -- NetworkCredential.Username?
