nHibernate-IStatelessSession和FetchMany返回多个父记录 [英] nHibernate - IStatelessSession and FetchMany returning multiple parent records

问题描述

我有以下linq语句:

I have the following linq statement:

var query = from p in session.Query<Parent>().FetchMany(x => x.Children)
            select p;

我最终为Children中的每个Child创建了一个新的Parent对象.因此，如果我有5个孩子，我会得到5个单独但相同的Parent对象.这是预期的行为吗?如果我使用ISession，则可以预期获得1个父级.

I end up with a new Parent object for each Child in Children. So if i had 5 Children, I would get 5 separate, but identical, Parent objects back. Is this the intended behavior? If i use ISession, I get 1 Parent as expected.

推荐答案

这是预料之中的，因为无状态会话不会跟踪对象.因此，每一行都会产生一个新实例.

This is expected, because Stateless Sessions do not track objects; therefore each row results in a new instance.
