How to get City Name using ReverseGeocodeQuery?

foreach (var item in Item[0].user)
                      {
                          AutoResetEvent done = new AutoResetEvent(true);
                          Uri uri = (new Uri("/Assets/Icons/default_image.png", UriKind.RelativeOrAbsolute));
                          Friend.Add(new FriendList { Name = item.firstname, Relationship = item.firstname == firstName ? "Self" : item.relationship, Image = item.prof_image_path == null ? uri.ToString() : item.prof_image_path, Date = item.date, Time = item.time, Id = item.id, Latitude = item.latitude, Longitude = item.longitude, EmailId = item.emailid });
                          ReverseGeocodeQuery query = new ReverseGeocodeQuery();
                          query.GeoCoordinate = new GeoCoordinate(Convert.ToDouble(item.latitude), Convert.ToDouble(item.longitude));
                          done.WaitOne();

                          query.QueryCompleted += (s,  e1) =>
                          {
                              if (e1.Error == null && e1.Result.Count > 0)
                              {

                                  Friend.Where(se => se.Location == "null").ToList();
                                  Friend.ForEach(se => { if (se.Id == item.id) { se.Location = city; } });
                                  Longlist.RenderTransform = (Transform)new TranslateTransform();

                                  Longlist.ItemsSource = Friend.ToList();
                                  loadingBar.IsVisible = false;
                                  LoadingCanvas.Visibility = Visibility.Collapsed;
                                  done.Set();
                              }

                          };
