我根据那个代码简单编写了一个软件

using System;
using System.Net;
using System.Net.Sockets;
using System.Net.NetworkInformation;
using System.Collections.Generic;


class App
{
    static void Main()
    {
        // 脚本执行
        DoGetHostAddresses(Dns.GetHostName());
        Console.WriteLine("GetPhysicalIP:");
        GetPhysicalIP();
    }
    public static void DoGetHostAddresses(string hostname)
    {
        IPAddress[] addresses = Dns.GetHostAddresses(hostname);

        Console.WriteLine("GetHostAddresses({0}) returns:", hostname);

        foreach (IPAddress address in addresses)
        {
            if (address.AddressFamily == AddressFamily.InterNetwork)
            {
                Console.WriteLine("    {0}", address);
            }
        }
    }

    // 获取物理网卡IP
    public static List<string> GetPhysicalIP()
    {
        List<string> ipList = new List<string>();
        List<string> macList = Mac(onlyEnabled: true);
        NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();

        foreach (NetworkInterface adapter in nics)
        {
            if (adapter.NetworkInterfaceType != NetworkInterfaceType.Ethernet)
            {
                continue;
            }
            PhysicalAddress address = adapter.GetPhysicalAddress();
            if (!macList.Contains(address.ToString()))
            {
                continue;
            }
            IPInterfaceProperties ipProperties = adapter.GetIPProperties();
            UnicastIPAddressInformationCollection ipCollection = ipProperties.UnicastAddresses;
            foreach (UnicastIPAddressInformation ip in ipCollection)
            {
                if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
                {
                    Console.WriteLine(ip.Address.ToString());
                    ipList.Add(ip.Address.ToString());
                }
            }
        }

        return ipList;
    }

    public static List<string> Mac(bool onlyEnabled = false)
    {
        List<string> macList = new List<string>();
        NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
        foreach (NetworkInterface adapter in nics)
        {
            if (onlyEnabled && adapter.OperationalStatus != OperationalStatus.Up)
            {
                continue;
            }
            PhysicalAddress address = adapter.GetPhysicalAddress();
            macList.Add(address.ToString());
        }
        return macList;
    }
}


【 在 VincentGe 的大作中提到: 】
: 那个程序上是没有问题的，根据知乎反编译提供的代码，可以认为没有问题。
