C#Xml-使用IXmlSerializable对派生类进行序列化

我有一个与XML序列化兼容的基类和一个实现IXmlSerializable的派生类.

在此示例中,基类确实实现了IXmlSerializable:

using System.Diagnostics;
using System.Text;
using System.Xml;
using System.Xml.Schema;
using System.Xml.Serialization;

namespace XmlSerializationDerived
{
    public class Foo
    {
        public int fooProp;

        public XmlSchema GetSchema()
        {
            return null;
        }

        public void ReadXml(XmlReader reader)
        {
            fooProp = int.Parse (reader.ReadElementString ("fooProp"));
        }

        public void WriteXml(XmlWriter writer)
        {
            writer.WriteElementString ("fooProp", fooProp.ToString ());
        }
    }

    public class Bar : Foo, IXmlSerializable
    {
        public new void ReadXml(XmlReader reader)
        {
            base.ReadXml (reader);
        }

        public new void WriteXml(XmlWriter writer)
        {
            base.WriteXml (writer);
        }

        static void Main(string[] args)
        {
            StringBuilder sb = new StringBuilder ();
            XmlWriter writer = XmlWriter.Create (sb);

            Bar bar = new Bar ();
            bar.fooProp = 42;

            XmlSerializer serializer = new XmlSerializer (typeof (Bar));
            serializer.Serialize (writer, bar);

            Debug.WriteLine (sb.ToString ());
        }
    }
}

这会产生以下输出:

42

但是,我想使用一个不实现IXmlSerializable 的基类.这可以防止使用base.Read/WriteXml.结果将是:

还有什么方法可以得到理想的结果吗？
