C# 获取本机指定类型指定网卡的Ip地址

1.简单方式 ，适用于单网卡

  string hostName = Dns.GetHostName();
            IPAddress[] addresses = Dns.GetHostAddresses(hostName);
            foreach (IPAddress address in addresses)
            {
                if (address.AddressFamily == AddressFamily.InterNetwork)
                {
                    //本机IPV4 地址
                }
                else if (address.AddressFamily == AddressFamily.InterNetworkV6)
                {
                    //本机IPV6 地址
                }
            }

单网卡区分IPV4与IpV6
