Question

I have a stored procedure that is returning data in this format:

HotelID | Price
---------------------
1 | 20
1 | 30
2 | 25
4 | 40
4 | 50

I’m getting the results like so:

ISingleResult<spResult> results = DataContext.sp();

I’d like to get a list of Hotels, based on the data returned from the stored procedure. Something like:

int[] uniqueHotelIds = GetUniqueHotelIdsFromResults(results);

List<Hotel> hotels = (from h in DataContext.Hotels
                      where uniqueHotelIds.Contains(h.HotelID)
                      select h).ToList();

Answer 1

I don’t have much experience with ISingleResult, but could you do:

int[] uniqueHotelIds = results.Select(x => x.HotelID).Distinct();
