C# NHibernate查询查找相关对象的相关对象

我有一个nHibernate查询问题，看起来很直截了当，但我似乎无法解决它

我正在创建一些简单的示例类来说明我的问题：

public class Car {
    public int Id { get; set; }
    public IList<Interior> InteriorParts { get; set; }
}

public class Interior {
    public int Id { get; set; }
    public InteriorProducer Producer { get; set; }
}

public class InteriorProducer {
    public int Id { get; set; }
}

为了创建一个nHibernate查询，我真的很难理解这一点

有什么想法吗

谢谢你，在hql

var query = session.CreateQuery
   ("select c from Cars c where c.InteriorParts.Producer.Id = :pid");
query.SetInt32("pid", producerId);
IList<Car> cars = query.List<Car>();

在hql中

var query = session.CreateQuery
   ("select c from Cars c where c.InteriorParts.Producer.Id = :pid");
query.SetInt32("pid", producerId);
IList<Car> cars = query.List<Car>();

.SetResultTransformer(Transformers.DistinctRootEntity)

var query = session.CreateQuery
   ("select c from Cars c where c.InteriorParts.Producer.Id = :pid");
query.SetInt32("pid", producerId);
IList<Car> cars = query.List<Car>();
