Linq NHibernate 查询子项

Question

我需要获取一些信息，但我是 NHibernate 的新手

我有这样的课程：

Person

   Id

   IdAddress

   Address

Address

   Id

   IdCity

   City

   IdNeighborhood

   Neighborhood

和班级

City

Neighborhood

我需要所有带有邻居 ID 的地址，这段代码是我搜索信息的地方，但这里只能获取城市：

using(var session = openSession()){

   var q = session.Query<Person>(a => Id == IdSearch)

           .Fetch(a => a.Address)

           .ThenFetch(a => a.City)

           .ToList();

   session.Clear();

}

我怎样才能获得邻里信息？

Answer 1

我找到了答案，在查询中，需要这样：using(var session = openSession()){&nbsp; &nbsp; var q = session.Query<Person>(a => Id == IdSearch)&nbsp; &nbsp; &nbsp; &nbsp;.Fetch(a => a.Address)&nbsp; &nbsp; &nbsp; &nbsp;.ThenFetch(a => a.City)&nbsp; &nbsp; &nbsp; &nbsp;.Fetch(a => a.Address)//search address again to have access to neighboorhoor&nbsp; &nbsp; &nbsp; &nbsp;.ThenFetch(a => a.Neighborhood)&nbsp; &nbsp; &nbsp; &nbsp;.ToList();&nbsp; &nbsp; session.Clear();}
