C#

var preResults = (from c in db.RATEPROCESSes
                                  join b in db.BATCHes on c.BATCHKEY equals b.id
                                  where c.MANIFESTDATE >= DateTime.Parse(fdate) && c.MANIFESTDATE <= DateTime.Parse(sdate) && c.ACCOUNTNBR == accountno
                                  select new { Pieces = b.pieces, ACCOUNTNBR = c.ACCOUNTNBR, Manifestdate = c.MANIFESTDATE, BATCHKEY = c.BATCHKEY })

var results=preresults.Select(x => new Batch_RateProcess { ACCOUNTNBR = x.ACCOUNTNBR, 
     Pieces = x.Pieces, Manifestdate = DateTime.Parse(x.Manifestdate.ToString()), 
     BATCHKEY = x.BATCHKEY.ToString()})
           .GroupBy(rateProcess=>rateProcess.ACCOUNTNBR);
