I cannot seem to even get started using an ArrayList using Visual Studio 2005. The dot operator does not provide the methods explained in the book I have like "add", "clear", etc....

If I use "private ArrayList ab = new ArrayList(5);" below then I get "No overload for method 'ArrayList' takes '1' arguments" compile error!

What am I doing wrong?

Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace ArrayList
{
    public partial class ArrayList : Form
    {
        private ArrayList ab = new ArrayList();

        public ArrayList()
        {
            InitializeComponent();
        }

        private void ArrayList_Load(object sender, EventArgs e)
        {
            // ab.add("Test"); -- This .add method is not allowed by the studio - Why?

        }  // end Load


    } // end partial class

} // end namespace ArrayList
