Reading the Login UserID from XP

[Guest]

Hej

I want to read the current Login at XP user Login to my C# Windows program.
I know how to use Namespace Microsoft.win32 and registryKey and Registry
class but I got a string i REG_SZ format not in normal Uni16 format by use
this little picse of code.

RegistryKey user = Registry.CurrentUser;

RegistryKey userid = user.OpenSubKey("Identities");


string UserIDStr = (string ) userid.GetValue("Last User ID");

user.Close();

So how to read the PC user Login in my proram so the user don't have to
write he/hers User ID again then they use the programmet beause I have to
store the users ID in a file

Best regard
Kim S.

Hey Kim,

You can try the: System.Security.Principal.WindowsIdentity.GetCurrent();
and/or have a look here:

Instead of going to the Registry, you could use
WindowsIdentity.GetCurrent():

using System.Security.Principal;
....
string UserIDStr = WindowsIdentity.GetCurrent().Name;
