我有一个专门的类,businessobjectlist,带有以下声明:

public class BusinessObjectList : List where T: BusinessObject {}

我想序列化这个类的对象,比如:

info.AddValue("myList", myList);

我试图添加接口ISerializable,但没有成功。

public class BusinessObjectList : List, ISerializable where T: BusinessObject {}

未序列化时,列表始终为空。

我认为list

编辑:

仅供将来参考,以下是整个类:

businessobjectlist.cs(当您调用save()时,它会自动在db all inserts和removes中保持,并将所有修改后的值保存在业务对象上):

[Serializable()]

public class BusinessObjectList : List,ISerializable where T: BusinessObject

{

public delegate void BusinessObjectListDeleteHandler(T objDeleted);

public event BusinessObjectListDeleteHandler deleteHandler;

List objsForDelete = new List();

public BusinessObjectList()

{

}

public new void Add(BusinessObject item)

{

base.Add(item);

}

public new T this[int index]

{

get

{

return (T)base[index];

}

}

public bool save()

{

foreach (T obj in objsForDelete)

{

if (deleteHandler != null)

deleteHandler(obj);

obj.delete();

}

objsForDelete.Clear();

foreach (BusinessObject obj in this)

{

obj.save();

}

return true;

}

public new void Clear()

{

foreach (BusinessObject obj in this)

{

//obj.delete();

objsForDelete.Add(obj);

}

base.Clear();

}

public new void Remove(BusinessObject obj)

{

// obj.delete();

objsForDelete.Add(obj);

base.Remove(obj);

}

public new void RemoveAt(int index)

{

objsForDelete.Add(this[index]);

base.RemoveAt(index);

}

#region ISerializable Members

public void GetObjectData(SerializationInfo info, StreamingContext context)

{

// should I do something here??

}

#endregion

}

和businessobject.cs:

[Serializable()]

public abstract class BusinessObject:ISerializable

{

public abstract bool save();

public abstract bool delete();

public abstract DbTransaction startTransaction();

public abstract void useTransaction(DbTransaction transaction);

public abstract DbTransaction getTransaction();

#region ISerializable Members

public void GetObjectData(SerializationInfo info, StreamingContext context)

{

// nothing to serialize here

}

#endregion

}
