方法一：利用注册表
using System;
using Microsoft.Win32;
class CardGrab
{
public static void
{
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
{
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
