如何在 C# 中获取忽略 Wifi（无线）LAN 连接的有线 LAN 连接列表

Question

在 C# 中，我想在运行时获取笔记本电脑的有线 LAN 连接列表，但我不需要任何 wifi 或无线 LAN。

我使用了各种方法来获取网络列表:-

ManagementClass

：

ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
 ManagementObjectCollection objMOC = objMC.GetInstances();

 foreach (ManagementObject objMO in objMOC)
        {
            if (!(bool)objMO["ipEnabled"])
                continue;
           this.textBox1.Text += (Convert.ToString(objMO["Description"])) + Environment.NewLine;
        }

上面的代码没有提供有关网络类型（wifi 或有线）的信息

NetworkInterface

班级：

foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())

        {
            this.textBox1.Text += nic.Name.ToString();    

            this.textBox1.Text += "MAC: " + nic.GetPhysicalAddress().ToString();

            this.textBox1.Text += "Type: " + nic.NetworkInterfaceType;
            this.textBox1.Text += "Description: " + nic.Description.ToString();
            this.textBox1.Text += "OperationalStatus: " + nic.OperationalStatus.ToString() + ;
        }

上面的代码给出了以太网 LAN 描述的列表。 甚至 wifi LAN 的 NetworkInterfaceType 也显示为以太网，例如： 类型：以太网 描述：Intel(R) Centrino(R) Ultimate-N 6300 AGN - 数据包调度程序微型端口

我的意思是没有办法区分哪个是无线网络还是有线网络。

我也尝试过

NativeWifi.WlanClient

，但是崩溃了。

  Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList(0);
        foreach (Wlan.WlanAvailableNetwork network in networks)
        {   
            if (network.dot11DefaultCipherAlgorithm == Wlan.Dot11CipherAlgorithm.WEP)
            {
                this.textBox1.Text = string.Format("Found WEP network with SSID {0}: ", GetStringForSSID(network.dot11Ssid)) + Environment.NewLine;
            }
        }

任何指导将不胜感激。 谢谢

Answer 1

NetworkInterface[] nics=NetworkInterface.GetAllNetworkInterfaces();

foreach(NetworkInterface adapter in nics)
{
  if(adapter.OperationalStatus==OperationalStatus.Up)
  {
    if(adapter.NetworkInterfaceType==NetworkInterfaceType.Wireless80211)
    {
      Console.WriteLine("Wifi");
    }
    else
    {
      Console.WriteLine("do your work");
    }
  }
}

Answer 2

这将消除除物理有线接口之外的所有接口

    NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
                                        foreach (var networkInterface in networkInterfaces)
                                        {
                                            
                                            if (networkInterface.NetworkInterfaceType != NetworkInterfaceType.Loopback &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Wwanpp &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Wwanpp2 &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Wireless80211 &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Unknown &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.HighPerformanceSerialBus &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Slip &&
                                            networkInterface.NetworkInterfaceType != NetworkInterfaceType.Tunnel && 
                                            networkInterface.OperationalStatus != OperationalStatus.NotPresent && 
                                            !networkInterface.Name.Contains("Bluetooth") && !networkInterface.Description.Contains("Virtual"))
                                            {
                                                Trace.Write($"Description :{networkInterface.Description}");
                                                Trace.WriteLine($"Interface Name: {networkInterface.Name}");
                
                
                                            }
                                        }
