i'm write that code by c#,hope connect the wireless(CISCO AIR AP-1231G-K9)

config the ap info:ptc001(ssid),Open Authentication(no addition)

void connectWireless()
        {
            NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
            WirelessZeroConfigNetworkInterface wzcInterface = null;
            foreach (NetworkInterface ni in interfaces)
            {
                if (!(ni is WirelessZeroConfigNetworkInterface)) continue;
                wzcInterface = ni as WirelessZeroConfigNetworkInterface;
                byte[] key = null;
                bool b = wzcInterface.AddPreferredNetwork("ptc001", true, key, 1, AuthenticationMode.Open,
                        WEPStatus.WEPDisabled, null);
                if (b)
                {
                    try
                    {

                        for (int i = 0; i < wzcInterface.PreferredAccessPoints.Count; i++)
                        {
                            string apName = wzcInterface.PreferredAccessPoints[i].Name;
                            if (apName.Equals("ptc001"))
                            {
                                if (!wzcInterface.AssociatedAccessPoint.Equals(apName))
                                {                                    ;
                                    b = wzcInterface.ConnectToPreferredNetwork(apName);
                                }
                            }

                        }
                    }
                    catch (Exception ee)
                    {
