C#获取本机IP 获取本地计算机已启用的网卡名、IP和MAC（默认ipv4）（最简洁实用）

我将网卡名、Ip、Mac装在List里，例如:(一般工控机就只有一个本地连接，笔记本会有WLAN)
LNetworkInformation[0].Name; 就是网卡名
LNetworkInformation[0].Ip; 就是Ip
LNetworkInformation[0].Mac; 就是Mac

使用方法：

CsNetWorkParam NetWorkParameter = new CsNetWorkParam();
List<Network> LNetworkInformation = NetWorkParameter.GetNetworkInformation();

以NetworkInterface.GetAllNetworkInterfaces();为核心获取接口所有信息

功能类：

    public class CsNetWorkParam
    {
        //使用方法：声明+调用

        public struct Network
        {
            public string Name;
            public string Mac;
            public IPAddress Ip;
        };

        public List<Network> GetNetworkInformation()
        {
            //存储集合声明
            List<Network> LNetwork = new List<Network>();

            NetworkInterface[] InterfacesInformation = NetworkInterface.GetAllNetworkInterfaces();//获取网络接口所有信息 包含未启用的网卡

            foreach (NetworkInterface networkInterface in InterfacesInformation)//遍历所有网络接口信息
            {
                bool bIsOpen = networkInterface.OperationalStatus == OperationalStatus.Up;//判断网络连接状态
                bool bIsLoopback = networkInterface.NetworkInterfaceType == NetworkInterfaceType.Loopback;//是否是 回环
                //Loopback       回环127.0.0.1
                //Wireless80211  无线网 
                //Ethernet       以太网
                if (bIsOpen && !bIsLoopback)
                {
                    //单个网卡声明
                    Network network = new Network();

                    //获取网卡名
                    network.Name = networkInterface.Name;

                    //获取ip
                    IPInterfaceProperties ipInterfaceProperties = networkInterface.GetIPProperties();//获取ip信息 包含ipv4和ipv6
                    foreach (UnicastIPAddressInformation ipAddressInformation in ipInterfaceProperties.UnicastAddresses)
                    {
                        if (ipAddressInformation.Address.AddressFamily == AddressFamily.InterNetwork)//判断是否符合ipv4
                        {
                            network.Ip = ipAddressInformation.Address;
                        }
                    }

                    //获取MAC
                    PhysicalAddress mac = networkInterface.GetPhysicalAddress();
                    string result = Regex.Replace(mac.ToString(), ".{2}", "$0:");//添加字符 .{插入位置} ${数组位置 默认0}{插入字符}
                    string strMac = result.Remove(result.Length - 1);
                    network.Mac = strMac;

                    LNetwork.Add(network);
                }
            }

            return LNetwork;
        }
    }
