Question

假设我有一个Parent和Child表，以及一个ParentChild表来维护它们之间的关系。

家长班：

public class Parent
{
    public virtual int ParentId { get; set; }
    public virtual bool Deleted { get; set; }

     public Parent()
     {
       _children = new HashedSet<Child>();
     }

     protected ISet<Child> _children;

     public virtual ISet<Child> children
     {
         get { return _children; }
         protected set { _children = value; }
     }
}

儿童班：

public class Child
{
    public virtual int ChildId { get; set; }
    public virtual bool Deleted { get; set; }

     public Child()
     {
       _parents = new HashedSet<Parent>();
     }

     protected ISet<Parent> _parents;

     public virtual ISet<Parent> parents
     {
         get { return _parents; }
         protected set { _parents = value; }
     }
}

和ParentChild类：

public class ParentChild 
{
    public virtual int ParentChildId { get; set; }
    public virtual Parent Parent { get; set; }
    public virtual Child Child { get; set; }
    public virtual int DisplayOrderIndex { get; set; }
    public virtual bool Deleted { get; set; }
}

我如何映射这些以便我可以对父对象进行更新，该对象还将使用其他数据（不仅仅是父/子ID）和子表更新联结表。

现在，我正在做：

父地图

public ParentMap()
{
    Table("Parent");
    Id(x => x.ParentId);
    Map(x => x.Deleted);
    HasMany(x => x.ParentChild)
        .Table("Parent_Child")
        .KeyColumn("ParentID")
        .Access.CamelCaseField(Prefix.Underscore)
        .Cascade.AllDeleteOrphan()
        .LazyLoad();
}

儿童地图

public ChildMap()
{
    Table("Child");
    Id(x => x.ChildId);
    Map(x => x.Deleted);
    HasMany(x => x.ParentChild)
        .Table("Parent_Child")
        .KeyColumn("ChildID")
        .Access.CamelCaseField(Prefix.Underscore)
        .Cascade.AllDeleteOrphan()
        .LazyLoad();
}

ParentChild Map

public ParentChildMap()
{
    Table("Parent_Child");
    Id(x => x.ParentChildId, "Parent_ChildID");
    References(x => x.Parent, "ParentID");
    References(x => x.Child, "ChildID");
    Map(x => x.DisplayOrderIndex);
    Map(x => x.Deleted);
}

但是，当我从Parent存储库中提取时，Parent对象的ParentChild集合中的Child是Castle.Proxy而不是Child类型。

如何进行此映射以获得所需的结果？

使用NHibernate在C＃中使用其他数据映射联结表
