Get log on user in .net core worker service

Question

I have a .net core 3.1.8 worker service. Is there a way to access the username of the Windows user that is set as the log on user for this service? I don't really see anything related to this in the documentation of the background service. Tried googling, but google only really finds stuff related to HttpContext, which I obviously do not have in a background service.

I only really need this for logging purposes, as in set the creator/modifying user in the DB when something is inserted/updated through the service, so my current solution is putting a serviceUserName property in appsettings.json and read it from there, but that just feels... dirty?

Answer 1

As seen in the comments, you can get user name of current thread with:

Environment.UserName

Reference:

Answer 2

There are several ways you can get the current user.

• Environment.UserName will return just the user name
• WindowsIdentity.GetCurrent() returns a WindowsIdentity object with the user's group memberships that also allows impersonation
• Thread.CurrentPrincipal returns an IPrincipal object, mainly used in web applications or authentication libraries.
