inheritance vs xml

[csharpula csharp]

Hello!

I have inheritance between classes which are the result of xml
serialization.
My question is how can I insure in serializaion stage that the hierarchy
in xml is according to inheritance hierarchy in classes?

Thank you very much!

Hi,

E.g. try to deserialize the class tree, then validate the result.

My question is : if I have ClassA:ClassB and in xml Class B element has
a memeber which is not of type A or B - is there an error in loading
this xml?

See XmlAnyAttributeAttribute / XmlAnyElementAttribute:

Also - it suggests no error is raised by default, but you can detect
unknown nodes and do what you want:

http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer.unknownnode.aspx

"By default, after calling the Deserialize method, the XmlSerializer
ignores XML nodes of unknown types. However, you can use this event to
handle such node types."

"By default, after calling the Deserialize method, the XmlSerializer
ignores XML attributes of unknown types. However, you can use this event
to handle such node types."
