c# - Linq NHibernate 查询子项

Question

我需要获取一些信息，但我是 NHibernate 的新手

我有这样的类(class):

Person
   Id
   IdAddress
   Address

Address
   Id
   IdCity
   City
   IdNeighborhood
   Neighborhood

和类

City
Neighborhood

我需要所有带有社区 ID 的地址，这段代码是我搜索资料的地方，但这里只获取城市:

using(var session = openSession()){
   var q = session.Query<Person>(a => Id == IdSearch)
           .Fetch(a => a.Address)
           .ThenFetch(a => a.City)
           .ToList();
   session.Clear();
}

我怎样才能获得社区信息？

Answer 1

我找到了答案，在查询中，需要这样:

using(var session = openSession()){
    var q = session.Query<Person>(a => Id == IdSearch)
       .Fetch(a => a.Address)
       .ThenFetch(a => a.City)
       .Fetch(a => a.Address)//search address again to have access to neighboorhoor
       .ThenFetch(a => a.Neighborhood)
       .ToList();
    session.Clear();
}
