Lambda expression help needed

Hopefully it's obvious what I'm trying to achieve just from the code

productVariants = productVariants.Where(pv => pv.AppliedDiscounts.Where(ad => ad.Id == discountId) as IList<ProductVariant>;

but here's some blurb anyway.

I'm trying to get the pv's from a list of pv's that have a certain discount code applied to them

Any help is appreciated.

Untested:

productVariants.Where(pv => pv.AppliedDiscounts.Where(ad => ad.Id == discountId).Count() > 0).ToList();

Still untested, but

Legend! Cheers Andy. Looks spot on to me
