对于引用主行的每一行,是否需要调用InsertonSubmit?

linq to sql-当插入一行(以及其他几行fk将指向此行的pk)时,是否足够执行[context].[maintable].insertonsubmit(row),或者是否也需要为其他行调用它?

下面是压缩代码示例(C):

//Forgive the contrived example (off the top of my head) :)

//Main row
Order order = new Order
{
    itemId     = (int)    data["itemNumber"],
    address    = (string) data["address"]
};
db.Orders.InsertOnSubmit(order); //would be nice to only have to submit here.

//Related rows
OrderPerson orderPerson = new OrderPerson
{
    Order = order,
    //other things, etc.
    orderRoleId = RoleIds.Customer
};
//Q: need to do "db.OrderPerson.InsertOnSubmit(orderPerson);" here?

OrderHistoryEntry historyEntry = new OrderHistoryEntry
{
    Order = order,
    //other things, etc.
    historyTypeId = HistoryIds.Ordered
};
//Q: need to do "db.OrderHistoryEntry.InsertOnSubmit(historyEntry);" here?

db.SubmitChanges();

是否足够: db.Orders.InsertOnSubmit(order); 或者,是否还需要为相关行(orderPerson和historyEntry)执行insertonSubmit?

最好只在主行运行一次。msdn示例就是这样做的,但它们都具有相反的关系(引用主行中的其他行)。

我很感激你的想法。
