是否有可靠的方法来获取C#中第一个本地以太网接口的IPv4地址?
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
if (nic.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
{...
这会找到与以太网适配器关联的本地IP地址,但也会找到Npcap Loopback Adapter(安装用于Wireshark)。
同样,使用以下代码似乎无法区分环回地址和以太网地址:
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{....
还有其他建议吗?

以下代码从首选界面获取IPv4。这也适用于虚拟机。
using System.Net;
using System.Net.Sockets;
public static void getIPv4()
{
try
{
using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, 0))
{
socket.Connect("10.0.1.20", 1337); // doesnt matter what it connects to
IPEndPoint endPoint = socket.LocalEndPoint as IPEndPoint;
Console.WriteLine(endPoint.Address.ToString()); //ipv4
}
}
catch (Exception)
{
Console.WriteLine("Failed"); // If no connection is found
}
}
