How I can get my first name last name with c# in my system (logging in windows with Active Directory username and pass)?
Is it possible to do that without going to the AD?
If you're using .Net 3.0 or higher, there's a lovely library that makes this practically write itself. System.DirectoryServices.AccountManagement
has a UserPrincipal
object that gets exactly what you are looking for and you don't have to mess with LDAP or drop to system calls to do it. Here's all it'd take:
Thread.GetDomain().SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsPrincipal principal = (WindowsPrincipal)Thread.CurrentPrincipal;
// or, if you're in Asp.Net with windows authentication you can use:
// WindowsPrincipal principal = (WindowsPrincipal)User;
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain))
{
UserPrincipal up = UserPrincipal.FindByIdentity(pc, principal.Identity.Name);
return up.DisplayName;
// or return up.GivenName + " " + up.Surname;
}
Note: you don't actually need the principal if you already have the username, but if you're running under the users context, it's just as easy to pull it from there.
