Display username from AD in ASP/.NET page

[VM]

How can I pass a user's display name or first+last name (not the login name)
from their AD account in an ASP page?

using System.DirectoryServices;

DirectoryEntry ent = new DirectoryEntry("LDAP://CN=My
User,DC=Fabrikam,DC=com");
Object ads = ent.NativeObject;
Type type = ads.GetType();
String firstName = (string) type.InvokeMember("FirstName",
BindingFlags.GetProperty, null, ads, null);
String lastName = (string) type.InvokeMember("LastName",
BindingFlags.GetProperty, null, ads, null);
