以正确的方式使用 NHibernate 更新实体集合
关于 NHibernate 如何工作的一个简单问题：
我有一个父实体，其中包含其他子实体的集合。这些子实体具有对其所属父实体的引用。现在我想向父实体实现一个 Add 方法，以向其添加一个子实体。该 Add 方法是否应该仅将子级添加到其新的父级集合中，或者还应该更新子级的父级引用，或者还应该从其先前的父级集合中删除添加的实体？我是否必须以该方法完成所有这些事情，或者 NHibernate 会为我做一些事情吗？
谢谢。
A simple question regarding how NHibernate works:
I have a parent entity that has a collection of other child entities. Those child entities have a reference to the parent entity they belong to. Now I want to implement an Add method to the parent entity that would add a child to it. Should that Add method only add the child to its new parents collection, or should it also update the parent reference of the child or should it also remove the added entity from its previous parents collection? Do I have to do all these things in that method or will NHibernate do something for me?
Thanks.

您绝对应该确保这种关系对于所有相关方来说都是“有效的”。
确保父级在其
children集合中拥有子级，并且子级在其parent引用中拥有父级，并且子级已从其旧中删除>parent（如果有的话）。最后一步是唯一我不确定是否强制执行的一步。You should definitely make sure that the relationship is "valid" for all parties involved.
Make sure that the parent has the child in its
childrencollection, and the the child has the parent in itsparentreference, and that the child is removed from its oldparent(if it had one). The last step is the only one for which I'm not sure it's mandatory.
