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
