Hi all,

I have a situation like this:

abstract class A
{
  public ArrayList List;
  // This list will contain objects of derived classes - like B
}

class B : A
{

}

I need to serialize class B with XmlSerializer but in the class A i
cannot define what type will go in the List (with XmlArrayItem) because
the class is abstract and I don't know what types can be derived from
it.

How can I define this in the class B? Is this approach ok:

class B : A
{
  [XmlArray, XmlArrayItem (Type = typeof(B))
  new public ArrayList List;
}

Thanks.
