C# 获取 ipv4的方法

1NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
2foreach (NetworkInterface adapter in nics)
3{
4    //判断是否为以太网卡
5    //Wireless80211         无线网卡    Ppp     宽带连接
6    //Ethernet              以太网卡   
7    //这里篇幅有限贴几个常用的，其他的返回值大家就自己百度吧！
8    if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
9    {
10        //获取以太网卡网络接口信息
11        IPInterfaceProperties ip = adapter.GetIPProperties();
12        //获取单播地址集
13        UnicastIPAddressInformationCollection ipCollection = ip.UnicastAddresses;
14        foreach (UnicastIPAddressInformation ipadd in ipCollection)
15        {
16            //InterNetwork    IPV4地址      InterNetworkV6        IPV6地址
17            //Max            MAX 位址
18            if (ipadd.Address.AddressFamily == AddressFamily.InterNetwork)
19                //判断是否为ipv4
20                Console.WriteLine(ipadd.Address.ToString());//获取ip
21        }
22    }
