Question

I just want the apartment complex count along with the other values. Only adding the count breaks the code. The error I get is “Sequence operators not supported for type ‘System.String’.” I have also tried changing apartCount to an int with no luck. Any help would be appreciated

using (var db = new DataClasses2DataContext())
        {
            var zips = (from s in db.ZipCodeServiceAvailabilities
                        join b in db.ZipCodeBoundaries on s.ZipCode equals b.ZipCode
                        join a in db.pdx_apart_views on s.ZipCode equals a.Zip_Code
                        where (s.IsServiced == 1 && b.Ordering % 10 == 0) 
                        orderby b.ZipCode

                        select new
                        {
                            zipCode = b.ZipCode.Trim(),
                            latitude = b.Latitude,
                            longitude = b.Longitude,
                            apartCount = a.Apartment_complex.Count()


                        }).ToArray();
             }

I think you miss group by clause in your query.

or you can use corolated sub query in select clause. please explain your question more
