How can I get the current user's login name from Windows Active Directory using C# code?
Simply,
string Name = new System.Security.Principal.WindowsPrincipal(System.Security.Principal.WindowsIdentity.GetCurrent()).Identity.Name;
OR
string Name = System.Environment.UserName
OR
string Name = Environment.GetEnvironmentVariable("USERNAME");
OR
string Name = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
works :)
