Windows中获取MAC地址的几种方法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_STA TS,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API-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 _ASTA T_{ADAPTER_STA TUS adapt;NAME_BUFFER NameBuff [30];}ASTA T, * PASTA T;ASTA T 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 = na;uRetCode = Netbios( &Ncb );printf( "The NCBRESET on LANA %d return code is: 0x%x \n",na, uRetCode );memset( &Ncb, 0, sizeof (Ncb) );Ncb.ncb_command = NCBASTA T;Ncb.ncb_lana_num = na;strcpy( Ncb.ncb_callname, "* " );Ncb.ncb_buffer = (char *) &Adapter;Ncb.ncb_length = sizeof(Adapter);uRetCode = Netbios( &Ncb );printf( "The NCBASTA T on LANA %d return code is: 0x%x \n",na, uRetCode );if ( uRetCode == 0 ){printf( "The Ethernet Number on LANA %d is:%02x%02x%02x%02x%02x%02x\n",na,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 outchar 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 _ASTA T_{ADAPTER_STA TUS adapt;NAME_BUFFER NameBuff[30];} ASTA T, * PASTA T;就可以这样调用来获取远程网卡MAC地址了：CString GetMacAddress(CString sNetBiosName){ASTA T 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 = NCBASTA T;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;}。
