var lastLocSuffix = _salespointAdapter.GetAll().Select(sp => new { LocSuffix = sp.LocSuffix }).OrderByDescending(sp => sp.LocSuffix).FirstOrDefault(); Int16 newSuffix = 1; if (lastLocSuffix != null) newSuffix = Convert.ToInt16(lastLocSuffix) + newSuffix; // Doesn't like this line salespoint.LocSuffix = newSuffix;I am trying to increment a number by 1. The number is supposed to be short. Why does it say something about cast if I declared the number to be short?
