         int totalRating = Convert.ToInt16(RatingQuery.FirstOrDefault().TotalRating);
        int totalnoofRating = db.tbl_Reviews.Count(n => n.HotelID == hotelID);

When answering a question please:
  1. Read the question carefully.
  2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
  3. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
