谢谢大家,经过大量努力,以下工作按预期为我工作
public decimal? ShopDeal()
{
decimal? shopdeal = 0;
var results = (from cartItems in db.Carts
where cartItems.CartId == ShoppingCartId
select new { cartItems.StoreId,cartItems.OrderLimit,cartItems.Duration,cartItems.ShopDiscount }).Distinct().ToList();
//db.Carts.Select(m => new { m.StoreId, m.OrderLimit, m.ShopDiscount, m.Giftback, m.Duration }.where()).Distinct().ToList();
foreach (var item in results)
{
decimal? shoptotal = (from cartItems in db.Carts
where cartItems.CartId == ShoppingCartId
&& cartItems.Item.StoreId == item.StoreId
select (decimal?)cartItems.Item.Price).Sum();
if (shoptotal >= item.OrderLimit && item.Duration == "Started")
{
shopdeal = shopdeal + shoptotal * item.ShopDiscount / 100;
}
}
return shopdeal;
}
regards
