C#如何同时获取IPv4和IPv6地址

要同时获取IPv4和IPv6地址，可以通过以下C#代码实现：

using System;using System.Net;using System.Net.Sockets;class Program{    static void Main()    {        string hostName = Dns.GetHostName();        IPAddress[] addresses = Dns.GetHostAddresses(hostName);        foreach (IPAddress address in addresses)        {            if (address.AddressFamily == AddressFamily.InterNetwork)            {                Console.WriteLine("IPv4 Address: " + address.ToString());            }            else if (address.AddressFamily == AddressFamily.InterNetworkV6)            {                Console.WriteLine("IPv6 Address: " + address.ToString());            }        }    }}

这段代码首先获取主机名，然后使用Dns.GetHostAddresses()方法获取主机的所有IP地址。然后通过遍历IP地址数组，分别检查每个IP地址的AddressFamily属性，以区分IPv4和IPv6地址。最后打印出相应的IPv4和IPv6地址。
