如何在c#中获取IPv6地址？

using System;
using System.Net;
using System.Net.NetworkInformation;

public class Program
{
    public static void Main()
    {
        NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
        
        foreach (NetworkInterface networkInterface in interfaces)
        {
            if (networkInterface.Supports(NetworkInterfaceComponent.IPv6))
            {
                IPInterfaceProperties properties = networkInterface.GetIPProperties();
                foreach (UnicastIPAddressInformation address in properties.UnicastAddresses)
                {
                    if (address.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6)
                    {
                        Console.WriteLine("IPv6 Address: " + address.Address.ToString());
                    }
                }
            }
        }
    }
}
