使用mono获取linux中的MAC地址

Question

如何在Linux上的Mono应用程序中获取计算机的MAC地址？

Answer 1

借用MSDN，在VS2008和单声道2.4.2.3（Debian 2.4.2.3 + dfsg-2）上测试：

using System;
using System.Net.NetworkInformation;

namespace ConsoleApplication2
{
    class Program
    {
        public static void ShowNetworkInterfaces()
        {
            IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
            NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
            Console.WriteLine("Interface information for {0}.{1}     ",
                    computerProperties.HostName, computerProperties.DomainName);

            if (nics == null || nics.Length < 1)
            {
                Console.WriteLine("  No network interfaces found.");
                return;
            }

            Console.WriteLine("  Number of interfaces .................... : {0}", nics.Length);

            foreach (NetworkInterface adapter in nics)
            {
                Console.WriteLine();
                Console.WriteLine(adapter.Description);
                Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, '='));
                Console.WriteLine("  Interface type .......................... : {0}", adapter.Netwo$
                Console.Write("  Physical address ........................ : ");
                PhysicalAddress address = adapter.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("-");
                    }
                }
                Console.WriteLine();
            }
        }

        static void Main(string[] args)
        {
            ShowNetworkInterfaces();
        }
    }
}

输出（linux）：

Interface information for hera.(none)
  Number of interfaces .................... : 2

lo
==
  Interface type .......................... : Loopback
  Physical address ........................ :

eth0
====
  Interface type .......................... : Ethernet
  Physical address ........................ : 00-26-xx-xx-xx-xx
