程序集包含类似的类

public class CustomPage : Page, ISearchable
{
    [Searchable]
    public virtual string CustomText { get; set; }
    public virtual string SearchableText { get; set; }
}

我想映射到 Lucene.net。我无法向这些类添加属性，也无法使用ISearchMapping，因为类型未知（没有引用该程序集）。

我该如何做映射？所有可用信息是所有类型都继承Page并实现ISearchable。唯一要映射的属性是SearchableText （在使用[Searchable]保存所有属性之前，将连接到该属性）。

You can use this design Generic DAO Object. I built an entire infrastructure using this implementation. You create an generic DAO and use it with any type of mapped object.

public GenericDAO<T>
{
     public List<T> Search(Criteria[] criterias)
     {}

     public T Save(T entity)
     {
     }

     public T Update(T entity)
     {
     }

     Public void Delete(T entity)
     {
     }

}

// any mapped object.
public MyMappedObject
{
   public virtual string ID {get; set;}
   public virtual string Name {get; set;}

   public MyMappedObject()
   {
       ID = Guid.NewGuid().ToString();
   }
}

// usage in code.
MyMappedObejct myMappedObjectInstance = new MyMappedObejct();
myMappedObjectInstance.Name = "new name";

GenericDAO<MyMappedObejct> myMappedObejctDao = new GenericDAO<MyMappedObject>();

// Insert
myMappedObjectInstance = myMappedObejctDao.Save(myMappedObjectInstance);

// Select
MyMappedObejct myMappedObjectInstance = myMappedObejctDao.Search().First();

// Update
myMappedObjectInstance.Name = "another name";
myMappedObjectInstance = myMappedObejctDao.Update(myMappedObjectInstance);

// Delete
myMappedObejctDao.Delete(myMappedObjectInstance);

This is a very simplified example, I made a much more complex version across more than a hundred classes and it works great.
