c++ windows 获取mac地址

以下方法只会返回多网卡的第一个MAC地址。网上有很多文章和源码来解决该问题，大多不全或有问题。本篇所有方法均经过整理调试，可直接使用。作者也不喜欢满篇帖代码，本篇贴代码是方便直接使用，请读者谅解。

下面奉上几种常用的方法：

#include <windows.h> #pragma comment(lib, "Netapi32.lib") namespace { bool GetAdapterInfo(int adapterNum, std::string& macOUT) memset(&Ncb, 0, sizeof(Ncb)); Ncb.ncb_command = NCBRESET; // 重置网卡，以便我们可以查询 Ncb.ncb_lana_num = adapterNum; return false; // 准备取得接口卡的状态块 memset(&Ncb, sizeof(Ncb), 0); Ncb.ncb_command = NCBASTAT; strcpy((char *) Ncb.ncb_callname, "*"); struct ASTAT ADAPTER_STATUS adapt; NAME_BUFFER nameBuff[30]; }adapter; memset(&adapter,sizeof(adapter), 0); Ncb.ncb_buffer = (unsigned char *)&adapter; Ncb.ncb_length = sizeof(adapter); char acMAC[32]; sprintf(acMAC, "%02X-%02X-%02X-%02X-%02X-%02X", int (adapter.adapt.adapter_address[0]), int (adapter.adapt.adapter_address[1]), int (adapter.adapt.adapter_address[2]), int (adapter.adapt.adapter_address[3]), int (adapter.adapt.adapter_address[4]), int (adapter.adapt.adapter_address[5])); macOUT = acMAC; return true; } bool GetMacByNetBIOS(std::string& macOUT) // 取得网卡列表 LANA_ENUM adapterList; NCB Ncb; memset(&Ncb, 0, sizeof(NCB)); Ncb.ncb_command = NCBENUM; Ncb.ncb_buffer = (unsigned char *)&adapterList; Ncb.ncb_length = sizeof(adapterList); // 取得MAC for (int i = 0; i < adapterList.length; ++i) if (GetAdapterInfo(adapterList.lana[i], macOUT))
