如何取得本机网卡的型号，IP地址，子网掩码和网关

方法一：利用注册表

using System;

using Microsoft.Win32;

class CardGrab

{

        public static void Main ()

        {

                RegistryKey start = Registry.LocalMachine;

                RegistryKey cardServiceName, networkKey;

                string networkcardKey = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkCards";

                string serviceKey = "SYSTEM\\CurrentControlSet\\Services\\";

                string networkcardKeyName, deviceName;

                string deviceServiceName, serviceName;

                RegistryKey serviceNames = start.OpenSubKey(networkcardKey);

                if (serviceNames == null)

                {

                        Console.WriteLine("Bad registry key");

                        return;

                }

                string[] networkCards = serviceNames.GetSubKeyNames();

                serviceNames.Close();

                foreach(string keyName in networkCards)

                {

                        networkcardKeyName = networkcardKey + "\\" + keyName;

                        cardServiceName = start.OpenSubKey(networkcardKeyName);

                        if (cardServiceName == null)

                        {

                                Console.WriteLine("Bad registry key: {0}",networkcardKeyName);

                                return;

                        }

                        deviceServiceName =(string)cardServiceName.GetValue("ServiceName");

                        deviceName = (string)cardServiceName.GetValue("Description");

                        Console.WriteLine("\nNetwork card: {0}", deviceName);

            

                        serviceName = serviceKey + deviceServiceName + "\\Parameters\\Tcpip";

                        networkKey = start.OpenSubKey(serviceName);

                        if (networkKey == null)

                        {

                                Console.WriteLine("  No IP configuration set");

                        }

                        else

                        {

                                string[] ipaddresses =(string[])networkKey.GetValue("IPAddress");

                                string[] defaultGateways =(string[])networkKey.GetValue("DefaultGateway");

                                string[] subnetmasks =(string[])networkKey.GetValue("SubnetMask");

                                foreach(string ipaddress in ipaddresses)

                                {

                                        Console.WriteLine("  IP Address: {0}",ipaddress);

                                }

                                foreach(string subnetmask in subnetmasks)

                                {

                                        Console.WriteLine("  Subnet Mask: {0}", subnetmask);

                                }

                                foreach(string defaultGateway in defaultGateways)

                                {

                                        Console.WriteLine("  Gateway: {0}",defaultGateway);

                                }

                                networkKey.Close();

                        }

                }

                start.Close();

                Console.ReadLine();

        }

}

方法二：使用WMI

当然要先添加System.Management.dll的引用

using System;

using System.Management;

class WMICardGrab

{

        public static void Main ()

        {

                ManagementObjectSearcher query = new

                ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'TRUE'");

                ManagementObjectCollection queryCollection = query.Get();

                foreach( ManagementObject mo in queryCollection )

                {

                        string[] addresses = (string[])mo["IPAddress"];

                        string[] subnets = (string[])mo["IPSubnet"];

                        string[] defaultgateways =(string[])mo["DefaultIPGateway"];

                        Console.WriteLine("Network Card: {0}",mo["Description"]);

                        Console.WriteLine("  MAC Address: {0}",mo["MACAddress"]);

                        foreach(string ipaddress in addresses)

                        {

                                Console.WriteLine("  IP Address: {0}", ipaddress);

                        }

                        foreach(string subnet in subnets)

                        {

                                Console.WriteLine("  Subnet Mask: {0}", subnet);

                        }

                        foreach(string defaultgateway
