IXmlSerializable and XmlSerializer together issue

Question

I have around 50 classes in polymorphic, inheritance relation. I used XmlSerializer to serialize them. Now for few classes I want to implement IXmlSerializable. So I started for one of class.This class not base class but derived directly from base class of all polymorphic relation.

After implementation, resultant XML contains tags only for above class which I have written in WriteXML method. There is no information for other classes. Very strange behavior!!!!

So please guide me to solve this issue, so that other classes information would maintain.

Answer 1

As I understand you correct - your xml contains properties that you implicit add in WriteXML (of current class)? But it is correct behavior. You should implicit add item as in example in description of interface.

If you need properties of base classes - add them. if you need properties of classes that inherit from this class - try to get them via reflection. Get Property Names using Reflection . But instead of typeof(MyClass) use .GetType() and check there how to get properties values.

Similar questions here and there .

End the ReadXml(XmlReader reader) method with the line

reader.Read();

seams to solves the problem...
