获取本地 有线 正在使用的网卡信息

包括 IP 掩码 网关 DNS服务地址 网卡地址 网卡名称等信息

代码如下

C# Code:

using System.Management;

        private void GetCurrentInfo()
        {
            ManagementObjectSearcher query = new
            ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'TRUE'");
            ManagementObjectCollection queryCollection = query.Get();
            try
            {
                foreach (ManagementObject mo in queryCollection)
                {
                    string[] addresses = (string[])mo["IPAddress"];
                    string[] subnets = (string[])mo["IPSubnet"];
                    string[] defaultgateways = (string[])mo["DefaultIPGateway"];
                    lblMacInfo.Text = "网卡: " + mo["Description"];

                    macAddress = (string)mo["MACAddress"];
                    txtBoard.Text = "网卡地址: \r\n" + macAddress + "\r\n";
                    ipAddress = addresses[0];
                    txtBoard.Text += "网络地址: \r\n" + ipAddress + "\r\n";
                    ipSubnet = subnets[0];
                    txtBoard.Text += "子网掩码: \r\n" + ipSubnet + "\r\n";
                    defaultGateway = defaultgateways[0];
                    txtBoard.Text += "默认网关: \r\n" + defaultGateway + "\r\n";
                    dnsServer1 = ((string[])mo["DNSServerSearchOrder"])[0];
                    txtBoard.Text += "主DNS服务:\r\n" + dnsServer1 + "\r\n";
                    dnsServer2 = ((string[])mo["DNSServerSearchOrder"])[1];
                    txtBoard.Text += "备DNS服务:\r\n" + dnsServer2;
                    break;
                }
            }
            catch (Exception ex) { MessageBox.Show(ex.Message); }
        }
