c# 区分虚拟网卡 获取真实网卡信息 判断网卡有线或无线

public void GetPhysicsNetworkAdapterInfo()
{
    ManagementObjectSearcher mos = new ManagementObjectSearcher(@"\\.\ROOT\StandardCimv2", "SELECT * FROM MSFT_NetAdapter WHERE Virtual=False");
    ManagementObjectCollection moc = mos.Get();
    foreach (ManagementObject mo in moc)
    {
        string driverDescription = mo["DriverDescription"]?.ToString();
        uint interfaceType = Convert.ToUInt32(mo["InterfaceType"] ?? 0);
        string macAdddr = mo["PermanentAddress"]?.ToString();
        Console.WriteLine("---------------------------------------");
        Console.WriteLine($"DriverDescription：{driverDescription}");
        Console.WriteLine($"MacAddr：{macAdddr}");
        Console.WriteLine($"InterfaceType：{interfaceType}");
    }
}

根据上面的结果对下面的进行过滤然后就可以实现网卡切换

void DisplayIPv4NetworkInterfaces()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    Console.WriteLine("IPv4 interface information for {0}.{1}",
        properties.HostName, properties.DomainName);
    Console.WriteLine();
    foreach (NetworkInterface adapter in nics)
    {
        // Only display informatin for interfaces that support IPv4.
        if (adapter.Supports(NetworkInterfaceComponent.IPv4) == false)
        {
            continue;
        }
        if (adapter.NetworkInterfaceType != NetworkInterfaceType.Wireless80211)
        {
            continue;
        }
        Console.WriteLine(adapter.Description);
        // Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, '='));
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        // Try to get the IPv4 interface properties.
        IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();
        if (p == null)
        {
            Console.WriteLine("No IPv4 information is available for this interface.");
            Console.WriteLine();
            continue;
        }
        // Display the IPv4 specific data.
        Console.WriteLine("  Index ............................. : {0}", p.Index);

        Console.WriteLine();
    }
