❔ Need help with a linq query
Hello, why does this query return nothing
List<Product> failedOrders = (
from order in orderData
from warehouse in warehouseData
from product in warehouse.Products
where product.ProductName == order.OrderName && product.Price <= order.PriceLimit && product.Quantity >= order.OrderQuantity
select new Product(product.ProductName, product.Quantity, product.Price)
).GroupBy(p => p.ProductName)
.Where(g => g.Sum(p => p.Quantity) < (
from o in orderData
where o.OrderName == g.Key
select o.OrderQuantity
).First())
.SelectMany(g => g)
.ToList();
