Windows中获取MAC地址的几种方法

转载：http://blog.csdn.net/legion8169/article/details/1656655

1.NDIS(DDK)通过驱动程序获取MAC地址

ndis规范中说明，网卡驱动程序支持ioctl_ndis_query_stats接口 
参数如下： 
OID_802_3_PERMANENT_ADDRESS ：物理地址 
OID_802_3_CURRENT_ADDRESS   ：mac地址 
于是我们的方法就得到了。 

首先，看看注册表，找一找网卡有几块，分别是什么设备名。 
具体位置和os有关，2000下在hlm/software/microsoft/windows nt/current version/networkcards。 

然后createfile(devicename,...)注意，要用linkname,因此 
还要加上"////.//device//". 

接着 
deviceiocontrol(hmac,IOCTL_NDIS_QUERY_STATS, 
OID_802_3_PERMANENT_ADDRESS/OID_802_3_CURRENT_ADDRESS...) 


具体的情况可以参看ddk下的 
OID_802_3_CURRENT_ADDRESS条目


2.NetAPI-2得到MAC (MSDN推荐方法) 

#include <windows.h>
//#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

typedef struct _ASTAT_
{
   ADAPTER_STATUS adapt;
   NAME_BUFFER    NameBuff [30];
}ASTAT, * PASTAT;

ASTAT Adapter;

int main (void)
{
      NCB Ncb;
      UCHAR uRetCode;
      char NetName[50];
      LANA_ENUM   lenum;
      int      i;

      memset( &Ncb, 0, sizeof(Ncb) );
      Ncb.ncb_command = NCBENUM;
      Ncb.ncb_buffer = (UCHAR *)&lenum;
      Ncb.ncb_length = sizeof(lenum);
      uRetCode = Netbios( &Ncb );
      printf( "The NCBENUM return code is: 0x%x /n", uRetCode );

      for(i=0; i < lenum.length ;i++)
       {
          memset( &Ncb, 0, sizeof(Ncb) );
          Ncb.ncb_command = NCBRESET;
          Ncb.ncb_lana_num = lenum.lana;

          uRetCode = Netbios( &Ncb );
          printf( "The NCBRESET on LANA %d return code is: 0x%x /n",
                  lenum.lana, uRetCode );

          memset( &Ncb, 0, sizeof (Ncb) );
          Ncb.ncb_command = NCBASTAT;
          Ncb.ncb_lana_num = lenum.lana;

          strcpy( Ncb.ncb_callname,  "*               " );
          Ncb.ncb_buffer = (char *) &Adapter;
          Ncb.ncb_length = sizeof(Adapter);

          uRetCode = Netbios( &Ncb );
          printf( "The NCBASTAT on LANA %d return code is: 0x%x /n",
                  lenum.lana, uRetCode );
          if ( uRetCode == 0 )
            {
             printf( "The Ethernet Number on LANA %d is:%02x%02x%02x%02x%02x%02x/n",
                  lenum.lana,
                  Adapter.adapt.adapter_address[0],
                  Adapter.adapt.adapter_address[1],
                  Adapter.adapt.adapter_address[2],
                  Adapter.adapt.adapter_address[3],
                  Adapter.adapt.adapter_address[4],
                  Adapter.adapt.adapter_address[5] );
             }
         }

} 

3.用COM API获取网卡MAC地址
     这种方法使用COM API创建一个GUID(全局唯一标识符)并从那里继承MAC地址。
GUID通常用来标识COM组件以及系统中的其他对象。它们是由MAC地址(结合其他东西)计算得来的，表面上MAC地址就包含在其中。
我说表面上是因为事实上并没有包含。我提供这种方法更多的是为了作为反面教材。您也许用这种方法能够得到MAC地址，但
有时候您只会得到随机的十六进制数值。下面的例子十分简单，无需多讲。我们使用CoCreateGuid创建GUID，并将最后六个字节
放入字符串中。它们可能是MAC地址，但并不是必然的。 

uuid.cpp 
#include <windows.h> 
#include <iostream> 
#include <conio.h> 

using namespace std; 

int main() 
{ 
   cout << "MAC address is: "; 
    
   // 向COM要求一个UUID。如果机器中有以太网卡， 
   // UUID最后的六个字节(Data4的2－7字节)应该是本地以太网卡的MAC地址。 
   GUID uuid; 
   CoCreateGuid(&uuid); 
   // Spit the address out 
   char mac_addr[18]; 
   sprintf(mac_addr,"%02X:%02X:%02X:%02X:%02X:%02X", 
   uuid.Data4[2],uuid.Data4[3],uuid.Data4[4], 
   uuid.Data4[5],uuid.Data4[6],uuid.Data4[7]); 
   cout << mac_addr << endl; 
   getch(); 
   return 0; 
} 


4.用NetAPI来获取网卡MAC地址

首先在头文件定义中加入#include "nb30.h" 

#pragma comment(lib,"netapi32.lib") 
typedef struct _ASTAT_ 
{ 
  ADAPTER_STATUS adapt; 
  NAME_BUFFER    NameBuff[30]; 
} ASTAT, * PASTAT; 


就可以这样调用来获取远程网卡MAC地址了： 

CString GetMacAddress(CString sNetBiosName) 
{ 
    ASTAT Adapter; 

    NCB ncb; 
    UCHAR uRetCode; 

    memset(&ncb, 0, sizeof(ncb)); 
    ncb.ncb_command = NCBRESET; 
    ncb.ncb_lana_num = 0; 

    uRetCode = Netbios(&ncb); 

    memset(&ncb, 0, sizeof(ncb)); 
    ncb.ncb_command = NCBASTAT; 
    ncb.ncb_lana_num = 0; 

    sNetBiosName.MakeUpper(); 

    FillMemory(ncb.ncb_callname, NCBNAMSZ - 1, 0x20); 

    strcpy((char *)ncb.ncb_callname, (LPCTSTR) sNetBiosName); 

    ncb.ncb_callname[sNetBiosName.GetLength()] = 0x20; 
    ncb.ncb_callname[NCBNAMSZ] = 0x0; 

    ncb.ncb_buffer = (unsigned char *) &Adapter; 
    ncb.ncb_length = sizeof(Adapter); 

    uRetCode = Netbios(&ncb); 
   
    CString sMacAddress; 

    if (uRetCode == 0) 
    { 
        sMacAddress.Format(_T("%02x%02x%02x%02x%02x%02x"), 
         Adapter.adapt.adapter_address[0], 
            Adapter.adapt.adapter_address[1], 
            Adapter.adapt.adapter_address[2], 
            Adapter.adapt.adapter_address[3], 
            Adapter.adapt.adapter_address[4], 
            Adapter.adapt.adapter_address[5]); 
    } 
    return sMacAddress; 
}
