Could you tell me why I can't use ArrayList though?

Type[] extraTypes = new Type[1];
     extraTypes[0] = typeof(person);
     XmlSerializer xs = new XmlSerializer(typeof(ArrayList), extraTypes);

    public class persons
    {

        p.firstname = "Tim";
        p.lastname = "Duncan";
        p.Age = 34;

        persons ps = new persons();
        ps.personlist.Add(p);

        FileStream fs = File.Create("C:\\Temp\\test.xml");

The problem was when I do

XmlSerializer xs = new XmlSerializer(typeof(ArrayList));

with or without the XMLInclude attribute, was not working!
