获取本地IPv4地址-优快云博客

本文介绍了一种使用C#编程语言来检查网络可用性并获取本地IPv4地址的方法。通过遍历所有网络接口并筛选出以太网类型的接口，进而获取其IPv4地址。

if (NetworkInterface.GetIsNetworkAvailable())
            {
                String ipv4Address = "";
                NetworkInterface[] nic = NetworkInterface.GetAllNetworkInterfaces();
                for (int i = 0; i < nic.Length; i++)
                {
if (NetworkInterfaceType.Ethernet == nic[i].NetworkInterfaceType)
                    {
                        //获取物理地址
                        PhysicalAddress phyAddress = nic[i].GetPhysicalAddress();
                        //获取IP地址属性
                        IPInterfaceProperties inInter = nic[i].GetIPProperties();
                        //获取单播地址
                        UnicastIPAddressInformationCollection unIpAddress = inInter.UnicastAddresses;
                        //获取多个单播地址
                        IEnumerator<UnicastIPAddressInformation> uipAddInfoEnum = unIpAddress.GetEnumerator();

                        {
                            //判断是否为IPV4地址
                            if (AddressFamily.InterNetwork == uipAddInfoEnum.Current.Address.AddressFamily)
