在C#中如何查找内部设备的mac地址而不是Router mac地址

Question

由于某些安全原因,我想在网络上获取我的软件用户的mac地址.但我可以通过以下方法获取路由器的mac地址.

public string GetMACAddress()
    {
        NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
        String sMacAddress = string.Empty;
        foreach (NetworkInterface adapter in nics)
        {
            if (sMacAddress == String.Empty)// only return MAC Address from first card  
            {
                IPInterfaceProperties properties = adapter.GetIPProperties();
                sMacAddress = adapter.GetPhysicalAddress().ToString();
            }
        } return sMacAddress;
    }

我需要在互联网上访问我的软件的系统的特定mac地址和该路由器的内部设备.那可能通过C#？

此方法是获取用户的 Mac 地址的最佳方法。
