C#获取本地连接IP地址、无线连接IP地址

获取本机本地ip地址：

        public static IPAddress GetServerIP()
        {
            IPAddress ipaddress = IPAddress.Parse("0.0.0.0");
            NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface ni in interfaces)
            {
                if (ni.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
                {
                    foreach (UnicastIPAddressInformation ip in
                        ni.GetIPProperties().UnicastAddresses)
                    {
                        if (ip.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                        {
                            ipaddress = ip.Address;
                        }
                    }
                }
            }
            return ipaddress;
        }
