如何使用C＃.net获取mac地址 [英] how to get mac address using C#.net

问题描述

我对以下代码有疑问

I have a question concerning the code below

using System;
using System.Text;
using System.Windows;
using System.Net.NetworkInformation;

namespace get_nick_mac
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {

            NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
            //for each j you can get the MAC
            PhysicalAddress address = nics[j].GetPhysicalAddress();
            byte[] bytes = address.GetAddressBytes();
            for (int i = 0; i < bytes.Length; i++)
            {
                // Display the physical address in hexadecimal.
                Console.Write("{0}", bytes[i].ToString("X2"));
                // Insert a hyphen after each byte, unless we are at the end of the
                // address.
                if (i != bytes.Length - 1)
                {
                    Console.Write("-");
                }
            }
        }
    }
}

我得到这个例外

当前上下文中不存在名称j

在线物理地址= nics [j] .GetPhysicalAddress（）;



感谢先进的

I get this exception
The name "j" does not exist in the current context
On line PhysicalAddress address = nics[j].GetPhysicalAddress();

Thanks in advanced

它应该可以工作，也许：

it should work, perhaps :

public static PhysicalAddress GetMacAddress()
            {
            foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
                {
                if (nic.NetworkInterfaceType == NetworkInterfaceType.Ethernet &&
                    nic.OperationalStatus == OperationalStatus.Up)
                    {
                    return nic.GetPhysicalAddress();
                    }
                }
            return null;
            }
