            var all = Collections.List(NetworkInterface.NetworkInterfaces);
            foreach (var inter in all)
            {
                var mac = (inter as NetworkInterface).GetHardwareAddress();
                if (mac == null) continue;

                var sb = new Java.Lang.StringBuilder();
                foreach (var b in mac)
                {
                    sb.Append((b & 0xFF).ToString("X2") + "");

                }
                s = sb.ToString();

            }
            return s;
        }
