注：亲测CPU序列号有重复的
一命令行方式、
打开命令提示符界面（cmd）输入wmic CPU get ProcessorID即可得到CPU序列号
二代码、
#include <iostream>
#include <>#include <string>
using namespace std;
void getcpuid(unsigned int CPUInfo[4], unsigned int InfoType);
void getcpuidex(unsigned int CPUInfo[4], unsigned int InfoType, unsigned int ECXValue);
char * get_cpuId();
void main(void)
{
char pCpuId[32] = "";
get_cpuId(pCpuId);
cout<<pCpuId<<endl;
system("pause");
return;
}
void get_cpuId(char *pCpuId)
{
int dwBuf[4];
getcpuid((unsigned int *)dwBuf, 1);
sprintf(pCpuId,"%08X",dwBuf[3]);
sprintf(pCpuId + 8, "%08X", dwBuf[0]);
return pCpuId;
}
void getcpuid(unsigned int *CPUInfo, unsigned int InfoType)
{
#if defined(__GNUC__)// GCC
__cpuid(InfoType, CPUInfo[0], CPUInfo[1], CPUInfo[2], CPUInfo[3]);
#elif defined(_MSC_VER)// MSVC
#if _MSC_VER >= 1400 //VC2005才支持__cpuid
__cpuid((int*)(void*)CPUInfo, (int)(InfoType));
#else //其他使用getcpuidex
getcpuidex(CPUInfo, InfoType, 0);
#endif
#endif
}
void getcpuidex(unsigned int *CPUInfo, unsigned int InfoType, unsigned int ECXValue)
{
#if defined(_MSC_VER) // MSVC
#if defined(_WIN64) // 64位下不支持内联汇编. 1600: VS2010, 据说VC2008 SP1之后才支持__cpuidex.
__cpuidex((int*)(void*)CPUInfo, (int)InfoType, (int)ECXValue);
#else
if (NULL==CPUInfo)
return;
_asm{
// load. 读取参数到寄存器.
mov edi, CPUInfo;
mov eax, InfoType;
mov ecx, ECXValue;
// CPUID
cpuid;
// save. 将寄存器保存到CPUInfo
mov [edi], eax;
mov [edi+4], ebx;
mov [edi+8], ecx;
mov [edi+12], edx;
}
#endif
#endif
}
