Linq query with nullable sum

Question

from i in Db.Items
select new VotedItem
{
    ItemId = i.ItemId,
    Points = (from v in Db.Votes
              where b.ItemId == v.ItemId
              select v.Poi         


        

Answer 1

Just to add another method into the mix :)

Where(q=> q.ItemId == b.ItemId && b.Points.HasValue).Sum(q=>q.Points.Value)

I had a similar scenario but I wasn't comparing an additional field when summing...

Where(q => q.FinalValue.HasValue).Sum(q=>q.FinalValue.Value);
