类里如何调用窗口控件?

namespace test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public delegate void dgaddlistbox(string text);
        public void addlistbox(string text)
        {
            if (listBox1.InvokeRequired)
            {
                dgaddlistbox dg = new dgaddlistbox(addlistbox);
                listBox1.Invoke(dg, new object[] { text });
            }
            else
            {
                if (listBox1.Items.Count > 100) listBox1.Items.RemoveAt(100);
                text = DateTime.Now.ToString() + "|" + text;
                listBox1.Items.Insert(0, text);
            }
        }
        public class myclass
        {
            public string text;
            public void my()
            {
                ...
                ...
                ...
                //这个位置要如何才能调用 addlistbox
                //调用位置
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            myclass mc = new myclass();
            mc.text = "my text";
            Thread t = new Thread(new ThreadStart(mc.my));
            t.IsBackground = tr
