測試代碼：

            bool _sucess = false;            CheckBox _finded = panel1.FindControl("checkBox1").Cast<CheckBox>(out _sucess);            if (_sucess)            {                MessageBox.Show(_finded.Name);            }            else            {                MessageBox.Show("Not Finded.");            }
