获取wince mac地址与IP地址解决方案

本人所使用的开发环境是VS2008，开发的系统所在移动终端版本为windows mobile 5.0。由于需要进行身份的验证，需要获取移动终端的MAC地址，于是在网上进行搜索，主要看到了三种方法来实现获取MAC地址，现记录如下。
第一种方法：使用ManagementClass 来获取。
殊不知，WinCE下并没有System.Management，这种方法根本行不通。
第二种方法：通过查找注册表来获取MAC地址。
这是获取注册表地址的代码：
txtMAC1.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress0");
其他的代码我这里就不列出来了，用这种方法我并没有获取到MAC地址。于是在网上下载了一个注册表查看工具，在移动终端中找，找遍了，发现并没有Comm\DM9CE1\Parms路径，再找其他的路径，都没找到有SoftwareMacAddress节点的。好吧，可能这种方法能获取MAC地址，但是我这个版本的不行。
第三种方法：通过SendARP获取MAC地址。
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.Collections;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.IO;
using System.Security.Cryptography;
using System.Net;
namespace WirelessRouteSystem
{
class SysInfo
{
private static string[] strEncrypt = new string[] { "1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "AA", "AB", "AC", "AD", "AE", "AF", "AG", "AH", "AI", "AJ", "AK", "AL", "AM", "AN", "AO", "AP" };
private static Int32 METHOD_BUFFERED = 0;
private static Int32 FILE_ANY_ACCESS = 0;
private static Int32 FILE_DEVICE_HAL = 0x00000101;
private const Int32 ERROR_NOT_SUPPORTED = 0x32;
private const Int32 ERROR_INSUFFICIENT_BUFFER = 0x7A;
private static Int32 IOCTL_HAL_GET_DEVICEID = ((FILE_DEVICE_HAL) << 16) | ((FILE_ANY_ACCESS) << 14) | ((21) << 2) | (METHOD_BUFFERED);
[DllImport("coredll.dll", SetLastError = true)]
private static extern bool KernelIoControl(Int32 dwIoControlCode, IntPtr lpInBuf, Int32 nInBufSize, byte[] lpOutBuf, Int32 nOutBufSize, ref Int32 lpBytesReturned);
[DllImport("Iphlpapi.dll", EntryPoint = "SendARP")]
public static extern uint SendARP(uint DestIP, uint SrcIP, byte[] pMacAddr, ref uint PhyAddrLen);
/// <summary>

/// </summary>
/// <returns></returns>
public string GetMac()
{
uint ip = 0;
string mac = string.Empty;
//取本机IP列表
IPAddress[] ips = Dns.GetHostEntry(Dns.GetHostName()).AddressList;
//取本机IP
byte[] ipp = ips[1].GetAddressBytes();
ip = (uint)((ipp[0]) | (ipp[1] << 8) | (ipp[2] << 16) | (ipp[3] << 24));
//取MAC
byte[] MacAddr = new byte[6];
uint PhyAddrLen = 6;
uint hr = SendARP(ip, 0, MacAddr, ref PhyAddrLen);
if (MacAddr[0] != 0 || MacAddr[1] != 0 || MacAddr[2] != 0 || MacAddr[3] != 0 || MacAddr[4] != 0 || MacAddr[5] != 0)
{
mac = MacAddr[0].ToString("X2") + ":" + MacAddr[1].ToString("X2") + ":" + MacAddr[2].ToString("X2") + ":" + MacAddr[3].ToString("X2") + ":" + MacAddr[4].ToString("X2") + ":" + MacAddr[5].ToString("X2");
}
return mac;
}
/// <summary>
///获取本机IP
/// </summary>
/// <returns></returns>
public string GetIpAddress()
{
string strHostName = Dns.GetHostName(); //得到本机的主机名
IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP
string strAddr = ipEntry.AddressList[1].ToString();
return strAddr;
}
}
}
通过 IP Helper API 中的 SendARP 发送 ARP 请求可以用来获取指定IP地址的MAC 地址，简单方便，缺点是不能跨越网关。
至于获取IP地址，本文已经给出了两种方法，都是通过NET下DNS类中方法获取。
