Question

我需要获取一些信息，但是我是NHibernate的新手

我有类似的课程：

Person
   Id
   IdAddress
   Address

Address
   Id
   IdCity
   City
   IdNeighborhood
   Neighborhood

和课程

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，但是这里只显示城市：

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

我还如何获得邻居信息？

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();
}
