获取防火墙状态

        //判断防火墙状态
        private static NetFwTypeLib.INetFwMgr GetFirewallManager()
        {
            const string CLSID_FIREWALL_MANAGER = "{304CE942-6E39-40D8-943A-B913C40C9CD4}";
            Type objType = Type.GetTypeFromCLSID(new Guid(CLSID_FIREWALL_MANAGER));
            return Activator.CreateInstance(objType) as NetFwTypeLib.INetFwMgr;
        }

        private void InitFireWall()
        {
            NetFwTypeLib.INetFwMgr netFwMgr = GetFirewallManager();
            if (netFwMgr.LocalPolicy.CurrentProfile.FirewallEnabled == true)
            {
                lbl_firewallStatus.ForeColor = Color.GreenYellow;
                btn_disableFirewall.Text = Enumeration.adsSystemLanguage.adsChinese == Program.core.environment.language ? "关闭防火墙" : "Close FireWall";
