From your code you now can call the following:

 private void button2_Click(object sender, EventArgs e)
        {
            _wp.OnNewWmlInformation += new WmlParser.OnNewWmlInformationEventHandler(_wp_OnNewWmlInformation);
            _wp.RequestData("http://10.0.220.1/stat.wml");

        }

        void _wp_OnNewWmlInformation(iWmlInfo info)
        {
            MessageBox.Show(info.BattCap);
        }
