I thought I had this, but I guess I don't

I would like my VB .NET web service to return an object, and a collection of that object.  I understand that I have to serialize the object and its collection, but I guess I don't know how to return what I want

In a distributed app, I am under the impression you create a class, and use a web service to expose limited functionality to that class, that is what I am trying to do. I have a 'People' collection class, and I want to return a set of people who are the children of person with ID='2'.  In my class I have a GetChildren(byval Person as int) as people.  I want to bring that collection back through the web service.  I have a lot of these to do, so re-creating, or mimicking the classes is not an option

I just need some sample code that I can run with

Thanks
