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 Program

    [Serializable]

        public string lastname;
        public int Age;

    }

    [
    XmlInclude(typeof(person))
    ]
    public class persons
    {
        public persons()
        {
        }

        public ArrayList personlist = new ArrayList();
    }

    [STAThread]
    static void Main()

        Application.EnableVisualStyles();

        person p = new person();

        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");

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

The problem was when I do

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

with or without the XMLInclude attribute, was not working!
