奇怪的网络设备

我正在使用 NetworkInformation 命名空间来列出所有网络设备。

NetworkInterface.GetAllNetworkInterfaces();

当我得到列表时，有一些奇怪的未知设备：

在此处输入图像描述

它们是什么？我应该、如果、那么如何摆脱它们？理论上它应该只显示本地连接和无线连接。在网络连接下我也找不到类似的安装内容。

原文

I am using NetworkInformation namespace to list all the network devices.

NetworkInterface.GetAllNetworkInterfaces();

When I get the list, there are some weird unknown devices:

enter image description here

What are they? And should I, and if, then how, get rid of them? In theory it should show only Local Area Connection and Wireless Connection. Under Network Connections I can't find anything like that installed either.

Windows 拥有物理硬件上不存在的网络“设备” - 它们用于各种用途，例如 VPN 连接（如隧道伪接口）和环回适配器（它响应 127.0.0.1

）可以通过使用 WMI 查询适配器列表来解析非物理地址

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(new SelectQuery("Win32_NetworkAdapter")))
{
    foreach (ManagementObject mo in searcher.Get())
    {
        if ((bool)mo["PhysicalAdapter"])
            Console.WriteLine(mo["Name"]);
    }
}

（取自 MSDN），

这只会返回物理设备，因为您将 PhysicalAdapter 属性的 true/false 值转换为 bool。

Windows has network 'devices' that don't exist in terms of physical hardware - they're used for various things, such as VPN connections (like that tunneling pseudo interface) and the loopback adapter, which is what responds to 127.0.0.1

You can parse the non-physical addresses by using WMI to query the list of adapters instead,

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(new SelectQuery("Win32_NetworkAdapter")))
{
    foreach (ManagementObject mo in searcher.Get())
    {
        if ((bool)mo["PhysicalAdapter"])
            Console.WriteLine(mo["Name"]);
    }
}

(taken from MSDN)

That'll only return physical devices, as you're casting the true/false value of the PhysicalAdapter property as bool.
