How to get default NIC Connection Name

Question

IMPORTANT EDIT: Back again on this subject. As you said there should be no default NIC, I\'m trying to understand if there is a way to detect all the NICs t

Answer 1

This is a dirty way of doing it as it can be optimized by incorporating LINQ, etc

using System.Net.NetworkInformation;

List Interfaces = new List();
foreach (var nic in NetworkInterface.GetAllNetworkInterfaces())
{
    if (nic.OperationalStatus == OperationalStatus.Up)
    {
        Interfaces.Add(nic);
    }
}


NetworkInterface result = null;
foreach (NetworkInterface nic in Interfaces)
{
    if (result == null)
    {
        result = nic;
    }
    else
    {
        if (nic.GetIPProperties().GetIPv4Properties() != null)
        {
            if (nic.GetIPProperties().GetIPv4Properties().Index < result.GetIPProperties().GetIPv4Properties().Index)
                result = nic;
        }
    }
}

Console.WriteLine(result.Name);

you'll probably want to tailor your results by using the results from nic.GetIPProperties() and nic.GetIPProperties().GetIPv4Properties()
