C#获取IP地址、子网掩码和网关地址

文这段代码是用C#语言实现获取IP地址、子网掩码和网关地址，首先要添加对程序集System.Management的引用

using System;
using System.Management;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection nics = mc.GetInstances();
foreach (ManagementObject nic in nics)
{
if (Convert.ToBoolean(nic["ipEnabled"]) == true)
{
Console.WriteLine((nic["IPAddress"] as String[])[0]);
Console.WriteLine((nic["IPSubnet"] as String[])[0]);
Console.WriteLine((nic["DefaultIPGateway"] as String[])[0]);
}
}
}
}
}
