获取全称.network interface C#

Question

I'm trying to find the.network interface name from ipconfig /all. So for example if the ipconfig /all output is:

Ethernet adapter Npcap Loopback Adapter:

   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Npcap Loopback Adapter
   Physical Address. . . . . . . . . : 01-00-4C-5F-5F-50
   DHCP Enabled. . . . . . . . . . . : Yes
   Autoconfiguration Enabled . . . . : Yes
   Autoconfiguration IPv4 Address. . : 169.254.183.10(Preferred)
   Subnet Mask . . . . . . . . . . . : 255.255.0.0
   Default Gateway . . . . . . . . . :
   NetBIOS over Tcpip. . . . . . . . : Enabled 

I want to print "Ethe.net adapter Npcap Loopback Adapter". This is what I've tried:

NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in interfaces)
{
     richTextBox1.AppendText(adapter.Name);
}

But it only prints "Ethe.net" instead of the full thing.

Looking at the output of ipconfig, I think the text you are seeing is made up of two things:

1. The NetworkInterfaceType property converted into standard strings
2. The Name property.

So you really just need a function to convert the enum into a string, for example it could be as simple as this:

private string GetNetworkTypeName(NetworkInterfaceType type) =>
    type switch
    {
        NetworkInterfaceType.Ethernet => "Ethernet adapter",
        NetworkInterfaceType.Wireless80211 => "Wireless LAN adapter",
        //etc etc...
        _ => "Other"
    };

And construct the name like this:

var interfaceName = $"{GetNetworkTypeName(adapter.NetworkInterfaceType)} {adapter.Name}";
