    public string getmoaddress()
    {
        string moaddress = " ";
        managementclass mc = new managementclass("win32_networkadapterconfiguration");
        managementobjectcollection moc2 = mc.getinstances();
        foreach (managementobject mo in moc2)
        {
            if ((bool)mo["ipenabled"] == true)
                moaddress = mo["macaddress"].tostring();
            mo.dispose();
        }
        return moaddress.tostring();
    }
