您好，List的派生类，List可以正常序列化。
但是派生类的属性如
public Presentation Presentation
，都没有被序列化。
请问您是否有属性可以用来控制派生类属性的序列化，还是要单独在实现序列化接口？！
[XmlInclude(typeof(List<XMLPNode>))]
[Serializable]
public class XMLConnectionPoints : List<XMLPNode>
{
private Presentation _oPresentation;
private Extent _oExtent;
private string _strNumPoints;
private string _strFlowIn;
private string _strFlowOut;
public XMLConnectionPoints()
{
_oPresentation = new Presentation();
_oExtent = new Extent();
}
[XmlElement]
public Presentation Presentation
{
get { return _oPresentation; }
set { _oPresentation = value; }
}
