控件遍历问题

Question

C#怎么遍历winForm上所有的控件。如有嵌套的控件怎么遍历里面的控件啊。我只找到WinForm上的控件，如控件里的控件就找不到了。递归算法怎样啊！

private void GetControls(ArrayList retList,Control ctrl)
        {
            foreach (Control ctl in ctrl.Controls)
            {
                retList.Add(ctl.Name);
                GetControls(retList, ctl);
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {            ArrayList retList=new ArrayList();
            this.GetControls(retList,this);
            this.listBox1.Items.AddRange(retList.ToArray());
        }
