Name of user running thread

[Mats-Lennart Hansson]

Hi,
I want to get the name of the owner of a thread. I have a component that can
be called from many different components so I want to trace which user that
owns the thread. Is this possible in c#?

Thanks,
Mats-Lennart

Hi Mats:

You can inspect the static CurrentPrincipal property of the Thread
class.

Yous hould be careful with this approach, because it is very possible to
change the principal for the thread, to something completely different from
a windows user.

Try this:
WindowsPrincipal threadPrincipal = Thread.CurrentPrincipal as
WindowsPrincipal;
if (threadPrincipal != null)
// Valid Windows principal
Console.WriteLine(threadPrincipal.Identity.Name);
else
// Current principal is not a Windows principal

It's also possible to think you've changed the principal for a thread
without having done so (this doesn't do impersonation). The property
is for server applications to check, not really to modify.

Apologies, I thought I was in the asp.net group.

If this is a component used outside of ASP.NET use
WindowsIdentity.GetCurrent() from the System.Security.Principal
namespace.
