Return multiple aggregate columns in LINQ

Question

I would like to translate the following SQL into LINQ:

SELECT
    (Select count(BidID)) as TotalBidNum,
    (Select sum(Amount)) as TotalBidVal
FROM Bids
         


        

Answer 1

You could do it using the Aggregate Clause.

Aggregate t In _dataContext.Bids
Into TotalBidNum = Count(BidID),
     TotalBidVal = Sum(Amount)

If you're using Fx4+ or an extension dll for Fx2, you could also benfit from parallelism by using

Aggregate t In _dataContext.Bids.AsParallel
