Asp.net 如何将此Linq查询转换为Lambda表达式

可能是这样的：

        foreach (lc_ShoppingCart sc in shQuery)
        {
            //Decrement the Product Table's Total Remaining row with the quantity
            var ProductInventoryQuery = (from pr in db.lc_ProductInventories
                                         join c in db.lc_ColorTables on pr.Color equals c.Color
                                         join s in db.lc_SizeTables on pr.Size equals s.Size
                                         where pr.ProductID == Convert.ToInt32(sc.ProductID)
                                         where pr.Color == c.Color
                                         where pr.Size == s.Size
                                         select pr).First();
            ProductInventoryQuery.Quantity = ProductInventoryQuery.Quantity - sc.Quantity;
        }
