CodePudding user response：

You can get the users full name from the active directory (using System.DirectoryServices.AccountManagement):

PrincipalContext context = new PrincipalContext(ContextType.Domain,Environment.UserDomainName);
string loginName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
UserPrincipal user = UserPrincipal.FindByIdentity(context, loginName);
string userName = user.Name; //=user.GivenName   " "   user.Surname;
