Thank you, Alex! I've been trying to make it work, but there's a twist
in my situation which I haven't added yet:
My UserControl-derived class is called Basic, and I have some classes
derived from Basic. I never directly use Basic, only its child
classes. I need to serialize a List<Basic>, filled with objects of the
child classes, but I don't know in advance what kind of objects are
used. I found examples how this should be done (a simple example, no
IXmlSerializable interface involved). So when I serialize/deserialize,
I use the following constructor for XmlSerializer class:
public XmlSerializer(Type type, Type[] extraTypes);
like this:
XmlSerializer ser = new XmlSerializer(typeof(List<Basic>), new Type[]
{ typeof(BasicChild1), ..., typeof(BasicChildN) } );
In the simple example, I see that there is an xsi:type="ChildClass"
attribute generated by the serializer. I guess serializer uses this
attribute to construct the object of the appropiate type when
deserializing.
Now the problem: How can I make this work with IXmlSerializable's
ReadXml?
I can generate the appropiate attribute in WriteXml with
XmlWriter.WriteAttributeString, but ReadXml should do something with
this attribute, right?
Thank you again for anyone helping me!

I have a class derived from UserControl.
I need to serialize an object of this class, but only some properties
of it, as not all properties are serializable (some of the properties
coming from UserControl are like that). When serializing, how
could I ignore all the properties coming from the UserControl
class? I know there is XmlIgnoreAttribute, but how could I set it
to every property of UserControl, as it is not my class?
Thank you very much,
Chris
