          }
          // Sort the indices from highest to lowest so that we
          // remove latter ones before earlier ones. In this way, the
          // indices of the rows doesn't change after the deletes.
          indicesToRemove.Sort();
          indicesToRemove.Reverse();

          foreach (int i in indicesToRemove)
