C#编程获取IP地址、子网掩码、网关地址

添加对程序集System.Management的引用

1. using System;
2. using System.Management;
3. namespace ConsoleApplication1
4. {
5.     class Program
6.     {
7.         static void Main(string[] args)
8.         {
9.             ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
10.             ManagementObjectCollection nics = mc.GetInstances();
11.             foreach (ManagementObject nic in nics)
12.             {
13.                 if (Convert.ToBoolean(nic["ipEnabled"]) == true)
14.                 {
15.                     Console.WriteLine((nic["IPAddress"] as String[])[0]);
16.                     Console.WriteLine((nic["IPSubnet"] as String[])[0]);
17.                     Console.WriteLine((nic["DefaultIPGateway"] as String[])[0]);
18.                 }
