serializing iderived classes in arrays


Hi all,

I have an ArrayList that contains items of type A. I declared the
XmlArrayItem atribute for that type.

Now I have an derived type B (from A) also contained in the ArrayList
but I get an error when serializing.

Can this be made without redeclaring the ArrayList special attributes?
The problem is that the class B is in different namespace!
public class Container
{
[XmlArray, XmlArrayItem(ty peof(A))]
public ArrayList Items = new ArrayList();
}

public class A
{
public string Name = "A object";
public A()
{
}
}

--- (different namespace!) -----
public class B : A
{
public B()
{
Name = "B object";
}
}

I think I could use XmlAttributeOve rrides but this way I'll have to
change the serializing code every time I derive a new class from A. :(

Hi, I've hit quite a strange problem with XmlSerializer on my W2K3 server. When I serialize/deserialize using an exe on my local computer (XP), everything works fine.

All, I have quite a challenging task ahead of me. I need to write an object model (for code access) based on a schema, which cannot be made into a dataset because of it's complexity. So I created a couple of objects and serializing it into XML based upon the schema works perfectly. The XML / Schema looks something like this:
