Hello All,

I am facing an prob please help.

I have following class.
class Product
        public int ProdCode { get; set; }
        public decimal NetAmount { get; set; }
        public List<int> BillDetailIds { get; set; }

In db there are two tables:

Table 1: Master table : containing following columns
BillId (PK), BillDate
Table 2: Details Table: containing following columns
BillDetailId (PK), BillId (FK), ProdCode, NetAmount

I want to show list from details table group by with Prodcode with sum of its amount. so i did below

var prodlist=Db.Details..GroupBy(x=>new{x.ProdCode}).select(x=>
                 new Product(){
                    ProdCode = Convert.ToInt32(x.FirstOrDefault().ProdCode),
                    NetAmount = x.Sum(s => s.Amount),

I'm stuck in BillDetailIds.
I need to store BillDetailIds on which groups is performed to create an Product object.

Help me please, thanks in advance

You could use this to resolve the problem:

 var prodlist = Db.Details.GroupBy(x=>new {x.ProdCode}).Select(x=>new Product()
   ProdCode = Convert.ToInt32(x.FirstOrDefault().ProdCode),
   NetAmount = x.Sum(s => s.Amount),
   BillDetailIds = Db.Details.Where(
                 z=>z.ProdCode == x.FirstOrDefault().ProdCode)

I hope this helps you

Kind regards
