例如,我有一个客户列表,每个客户都有一个订单列表。现在,我希望获得所有未付订单的客户列表(假设这是状态2)。与该客户列表一起,我还希望获得未付订单列表。
例如我有这个:
from c in mycontext.Customers.Include("Orders")
select c
在何处或如何添加条件以查找状态为== 2的订单以及如何将这些订单包含在客户列表中?

,否则
from c in mycontext.Customers.Include("Orders")
where c.Orders.Any(order => order.status == 2)
select c
或
from c in mycontext.Customers.Include("Orders")
let newObject = {
Customer = c,
NotPaidOrders = c.Orders.Where(order => order.status == 2).ToList()
}
where newObject.NotPaidOrders.Any()
select newObject

试试这个:
from c in mycontext.Customers.Include("Orders")
from order in c.Orders
where order.status == 2
select order
或者为什么不简单地这样做:
from order in mycontext.Orders
where order.status == 2
select order
