如何用C语言获取硬盘或主板或CPU的序列号

获取CPU序列号要使用

汇编指令

比较麻烦

static

DWORD

g_eax;

//

存储返回的eax

static

DWORD

g_ebx;

//

存储返回的ebx

static

DWORD

g_ecx;

//

存储返回的ecx

static

DWORD

g_edx;

//

存储返回的edx

void

Executecpuid(DWORD

veax)

{

asm("cpuid"

:"=a"(g_eax),

"=b"(g_ebx),

"=c"(g_ecx),

"=d"(g_edx)

:"a"(g_eax));

}

int

isSupport;

void

GetSerialNumber(WORD

nibble[6])

{

Executecpuid(1);

//

执行cpuid，参数为

eax

=

1

isSupport

=

g_edx

&

(1<<18);

//

edx是否为1代表CPU是否存在序列号

if

(FALSE

==

isSupport)

//

不支持，返回false

{

return

;

}

Executecpuid(3);

//

执行cpuid，参数为

eax

=

3

memcpy(&nibble[4],

&g_eax,

4);

//

eax为最高位的两个WORD

memcpy(&nibble[0],

&g_ecx,

8);

//

ecx

和

edx为低位的4个WORD

}

function GetVolumeID : string;

var

vVolumeNameBuffer: array[0255]of Char;

vVolumeSerialNumber: DWORD;

vMaximumComponentLength: DWORD;

vFileSystemFlags: DWORD;

vFileSystemNameBuffer: array[0255]of Char;

begin

if GetVolumeInformation('C:\', vVolumeNameBuffer, SizeOf(vVolumeNameBuffer),

@vVolumeSerialNumber, vMaximumComponentLength, vFileSystemFlags,

vFileSystemNameBuffer, SizeOf(vFileSystemNameBuffer)) then

begin

Result := IntToHex(vVolumeSerialNumber, 8);

end;

end;

同LS BS 4L &易语言LZ的问题应该是没有声明一个RegistryKeyRegistryKey regNew_GetDisk = RegistryLocalMachineOpenSubKey(@\"\\HardWare\\Devicemap\\Scsi\\Scsi port 0\\Scsi Bus 0\\Target Id\\\\Logical Unit Id 0\", false);string Value = regNew_GetDiskGetValue(\"Identifier\",\"none\")ToString ();MessageBoxShow(Value);regNew_GetDiskClose();注意引用MicrosoftWin32 namespace

Const wbemFlagReturnImmediately = &h10

Const wbemFlagForwardOnly = &h20

Set objWMIService = GetObject("winmgmts:\\\root\CIMV2")

Set colItems = objWMIServiceExecQuery("SELECT FROM Win32_DiskDrive", "WQL", _

wbemFlagReturnImmediately + wbemFlagForwardOnly)

For Each objItem In colItems

WScriptEcho "硬盘序列号: " & objItemSignature

WScriptEcho

Next

直接保存成vbs，双击，运行就可以看到了
