文章讨论了在一台有多重MAC地址的电脑上，如何通过代码确定并获取当前网络连接（WiFi或以太网）的MAC地址。提供的代码示例展示了如何遍历网络接口，检查类型（如Wireless80211或Ethernet）和状态，以找到活跃的MAC地址。

今天发现获取mac地址发现了一个问题，有的电脑有多个mac地址怎么判断是当前网络用的mac呢？

下面代码获取mac 拿到的是众多mac地址中的第一个

private static string GetMacAddress()
    {
        string physicalAddress = "";

        NetworkInterface[] nice = NetworkInterface.GetAllNetworkInterfaces();

        for (int i = 0; i < nice.Length; i++)
        {
            print("sdsdsd :  " + nice[i].ToString());
        }
        foreach (NetworkInterface adaper in nice)
        {
            print("nice:" + nice);
            Debug.Log("ad: " + adaper.Description);

            if (adaper.Description == "en0")
            {
                physicalAddress = adaper.GetPhysicalAddress().ToString();
                break;
            }
            else
            {
                physicalAddress = adaper.GetPhysicalAddress().ToString();

                if (physicalAddress != "")
                {
                    break;
                };
            }
        }
       
        return physicalAddress;
    }

当前wifi使用的mac地址，如果想要以太网的mac 将Wireless80211 改为Ethernet

public static string GetmacAddress()
    {
        string strphysicalAddress = "";
        var interfaces = NetworkInterface.GetAllNetworkInterfaces();
        foreach (var iface in interfaces)
        {
            if (iface.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 && iface.OperationalStatus == OperationalStatus.Up)
            {
                var physicalAddress = iface.GetPhysicalAddress();
                var macAddress = physicalAddress.ToString();
                Debug.Log("Current MAC address: " + macAddress);
                strphysicalAddress = macAddress;
                break;
            }
            else
            {
                var physicalAddress = iface.GetPhysicalAddress();
                var macAddress = physicalAddress.ToString();
                Debug.Log("没网的 MAC address: " + macAddress);
            }
        }
       
        return strphysicalAddress;
    }
