我有一个基类，另一个派生自它。我们假设，基类有20个成员，派生出5个成员。只有派生类是可序列化的。序列化/反序列化派生类
我实例化后，派生类的对象有全部25个成员。现在我怎么才能序列化派生类的5个成员？当我使用“this”进行serizalize或反序列化时，整个班级（全部25个成员）被序列化，然后反序列化。
下面的代码片段（不完整）：
// Base class definition.
public abstract class baseMyClass
{
// declaration of members
}
...
// Derived class definition.
[Serializable]
public sealed class MyDerivedClass : baseMyClass
{
// declaration of members
}
...
// Serializing the object.
StringWriter writer = new StringWriter();
XmlSerializer xs = new XmlSerializer(typeof(MyDerivedClass));
xs.Serialize(writer, this);
...
// Deserializing the object.
StringReader reader = new StringReader(System.Text.Encoding.UTF8.GetString(data));
XmlSerializer xs = new XmlSerializer(typeof(MyDerivedClass));
MyDerivedClass objMyDerivedClass = (MyDerivedClass)(xs.Deserialize(reader));
我找不到任何类似的例子。如果你知道一个，请告诉我。
感谢您的帮助。
