如何在C#中更改DNS地址

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

public class DNSChanger
{
    public static void ChangeDNS(string interfaceName, string[] dnsAddresses)
    {
        NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();

        foreach (NetworkInterface networkInterface in interfaces)
        {
            if (networkInterface.Name == interfaceName)
            {
                IPInterfaceProperties ipProperties = networkInterface.GetIPProperties();

                // 清除当前DNS服务器地址
                ipProperties.DnsAddresses.Clear();

                // 添加新的DNS服务器地址
                foreach (string dnsAddress in dnsAddresses)
                {
                    IPAddress dnsServer;
                    if (IPAddress.TryParse(dnsAddress, out dnsServer))
                    {
                        ipProperties.DnsAddresses.Add(dnsServer);
                    }
                }

                // 保存更改后的网络接口配置
                networkInterface.SetIPProperties(ipProperties);
                Console.WriteLine("DNS地址已成功更改。");
                return;
            }
        }

        Console.WriteLine("未找到指定的网络接口。");
    }

    public static void Main()
    {
        string interfaceName = "以太网"; // 需要更改DNS地址的网络接口名称
        string[] dnsAddresses = { "8.8.8.8", "8.8.4.4" }; // 新的DNS服务器地址列表

        ChangeDNS(interfaceName, dnsAddresses);
    }
}
