Question

让我说,我有两个班子:

public class A
{
  public virtual int Id { get; set; }
  public virtual Object1 Obj { get; set; }
}

public class B : A
{
  public new virtual Object2 Obj { get; set; }
}

I use Fluent NHibernate and I have created two different mappings for the two classes. However, when I try to query class A in my repository, FNH finds both class B and A, which kind of makes sense since both are A.

例(这些标准将涉及A和B):

public List<T> GetByName(string name)
{
  return Session.CreateCriteriaOf<A>.Add(Restrictions...);
}

When writing CreateCriteriaOf<A>, I only want to query over A - not B. How can I solve my problem?

Answer 1

我认为,在A和B都来自共同(传统)基础类型的情况下,你能更好地造就遗产树。然后,NHibernate可以通过进行区分。

当然,你的数据模型应当考虑到这一点,因此我希望你的模式不会以任何方式加以规定。
