DirectoryEntry dir = new DirectoryEntry();
    dir.Path = "LDAP://YourActiveDirServername ";        
    DirectorySearcher sea = new DirectorySearcher(dir);
    sea.Filter = "(sAMAccountName=Uname)";
    SearchResult seares = sea.FindOne();      
    StringBuilder str = new StringBuilder();
    System.DirectoryServices.ResultPropertyCollection prop = seares.Properties;
    ICollection coll = prop.PropertyNames;
    IEnumerator enu = coll.GetEnumerator(); 
        while (enu.MoveNext())
        {
            str.Append(enu.Current + " = " + seares.Properties[enu.Current.ToString()][0] + "\n");
