获取网卡信息

引入的命名空间

代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.NetworkInformation;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ShowAdapterInfo();
        }

        /// <summary>  
        /// 显示网卡信息  
        /// </summary>  
        private void ShowAdapterInfo()
        {
            NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
            lst_NetworkAdapter.Items.Add("适配器个数：" + adapters.Length);
            int index = 0;

            foreach (NetworkInterface adapter in adapters)
            {
                index++;
                //显示网络适配器描述信息、名称、类型、速度、MAC 地址  
                lst_NetworkAdapter.Items.Add("---------------------第" + index + "个适配器信息---------------------");
                lst_NetworkAdapter.Items.Add("描述信息：" + adapter.Name);
                lst_NetworkAdapter.Items.Add("类型：" + adapter.NetworkInterfaceType);
                lst_NetworkAdapter.Items.Add("速度：" + adapter.Speed / 1000 / 1000 + "MB");
                lst_NetworkAdapter.Items.Add("MAC 地址：" + adapter.GetPhysicalAddress());

                //获取IPInterfaceProperties实例  
                IPInterfaceProperties adapterProperties = adapter.GetIPProperties();

                //获取并显示DNS服务器IP地址信息  
                IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
                if (dnsServers.Count > 0)
                {
                    foreach (IPAddress dns in dnsServers)
                    {
                        lst_NetworkAdapter.Items.Add("DNS 服务器IP地址：" + dns + "
");
                    }
                }
                else
                {
                    lst_NetworkAdapter.Items.Add("DNS 服务器IP地址：" + "
");
                }
            }
        }  
    }
}
