Getting user full name from Login information in MOSS

using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using Microsoft.Office.Server.UserProfiles;
using Microsoft.Office.Server;





SPSite _site = new SPSite("http://server/");
ServerContext scontext = ServerContext.GetContext(_site);
SPUser memb = _site.OpenWeb().CurrentUser;
UserProfileManager upm = new UserProfileManager(scontext);
UserProfile up = upm.GetUserProfile(memb.LoginName);
MessageBox.Show(up["FirstName"].ToString() + up["LastName"].ToString());




Hope this will help.
