从c＃中获得了此代码的系统序列号（不是我）
public static string getSystemSerialNumber()
{
string mbInfo = string.Empty;
ManagementScope scope = new ManagementScope(@"\\" + Environment.MachineName + @"\root\cimv2");
scope.Connect();
ManagementObject wmiClass = new ManagementObject(scope, new ManagementPath("Win32_BaseBoard.Tag=\"Base Board\""), new ObjectGetOptions());
foreach (PropertyData propData in wmiClass.Properties)
{
if (propData.Name == "SerialNumber")
{
mbInfo = Convert.ToString(propData.Value);
break;
}
}
return mbInfo;
}
它返回以下字符串：/ 8ZBPX ** / CN12966791 **** / ，我想获取上面的确切字符串，但使用c ++（windows10）。我发现了这个code：
system("wmic bios get serialnumber > sn.txt");
wchar_t sn[16];
FILE* fp = fopen("sn.txt", "r, ccs=UTF-8");
fgetws(sn, 16, fp); //dummy read of first line
fgetws(sn, 16, fp); //now sn contains 2nd line
fclose(fp); //cleanup temp file
remove("sn.txt");
printf("The serial Number is: %ws\n", sn);
，它返回以下字符串：8ZBPX **，我不知道如何找到后面的信息链。
如何在C ++中获取完整的系统序列号？ 非常感谢！

您引用的SO答案：C++ How do I pass a system serial number into a variable?
引用了一些MSDN链接，其中之一可将您定向到Example: Getting WMI Data from the Local Computer。
本文是从您的问题创建'getSystemSerialNumber（）'函数转换的一个很好的起点。
逐字阅读该文章中的代码，您只需更改几行即可将其转换为查询序列号（为清晰/正确起见，还应更改其他一些注释行和输出行）。
然后您可以进一步修改'main（）'函数以返回该值以模仿您的C＃函数。
这是修改后的版本：
#define _WIN32_DCOM
#include <iostream>
using namespace std;
#include <comdef.h>
#include <Wbemidl.h>
#pragma comment(lib, "wbemuuid.lib")
int main(int argc, char** argv)
{
HRESULT hres;
// Step 1: --------------------------------------------------
// Initialize COM. ------------------------------------------
hres = CoInitializeEx(0, COINIT_MULTITHREADED);
if (FAILED(hres))
{
cout << "Failed to initialize COM library. Error code = 0x"
<< hex << hres << endl;
return 1; // Program has failed.
}
// Step 2: --------------------------------------------------
// Set general COM security levels --------------------------
hres = CoInitializeSecurity(
NULL,
-1, // COM authentication
NULL, // Authentication services
NULL, // Reserved
RPC_C_AUTHN_LEVEL_DEFAULT, // Default authentication
RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation
NULL, // Authentication info
EOAC_NONE, // Additional capabilities
NULL // Reserved
);
if (FAILED(hres))
{
cout << "Failed to initialize security. Error code = 0x"
<< hex << hres << endl;
CoUninitialize();
return 1; // Program has failed.
}
// Step 3: ---------------------------------------------------
// Obtain the initial locator to WMI -------------------------
IWbemLocator* pLoc = NULL;
hres = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID*)&pLoc);
if (FAILED(hres))
{
cout << "Failed to create IWbemLocator object."
<< " Err code = 0x"
<< hex << hres << endl;
CoUninitialize();
return 1; // Program has failed.
}
// Step 4: -----------------------------------------------------
// Connect to WMI through the IWbemLocator::ConnectServer method
IWbemServices* pSvc = NULL;
// Connect to the root\cimv2 namespace with
// the current user and obtain pointer pSvc
// to make IWbemServices calls.
hres = pLoc->ConnectServer(
_bstr_t(L"ROOT\\CIMV2"), // Object path of WMI namespace
NULL, // User name. NULL = current user
NULL, // User password. NULL = current
0, // Locale. NULL indicates current
NULL, // Security flags.
0, // Authority (for example, Kerberos)
0, // Context object
&pSvc // pointer to IWbemServices proxy
);
if (FAILED(hres))
{
cout << "Could not connect. Error code = 0x"
<< hex << hres << endl;
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
cout << "Connected to ROOT\\CIMV2 WMI namespace" << endl;
// Step 5: --------------------------------------------------
// Set security levels on the proxy -------------------------
hres = CoSetProxyBlanket(
pSvc, // Indicates the proxy to set
RPC_C_AUTHN_WINNT, // RPC_C_AUTHN_xxx
RPC_C_AUTHZ_NONE, // RPC_C_AUTHZ_xxx
NULL, // Server principal name
RPC_C_AUTHN_LEVEL_CALL, // RPC_C_AUTHN_LEVEL_xxx
RPC_C_IMP_LEVEL_IMPERSONATE, // RPC_C_IMP_LEVEL_xxx
NULL, // client identity
EOAC_NONE // proxy capabilities
);
if (FAILED(hres))
{
cout << "Could not set proxy blanket. Error code = 0x"
<< hex << hres << endl;
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
// Step 6: --------------------------------------------------
// Use the IWbemServices pointer to make requests of WMI ----
// Query the system board
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM Win32_Baseboard WHERE Tag = \"Base Board\""),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if (FAILED(hres))
{
cout << "Query for system board serial number failed."
<< " Error code = 0x"
<< hex << hres << endl;
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
// Step 7: -------------------------------------------------
// Get the data from the query in step 6 -------------------
IWbemClassObject* pclsObj = NULL;
ULONG uReturn = 0;
while (pEnumerator)
{
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,
&pclsObj, &uReturn);
if (0 == uReturn)
{
break;
}
VARIANT vtProp;
// Get the value of the Serial Number property
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
wcout << " Serial Number : " << vtProp.bstrVal << endl;
VariantClear(&vtProp);
pclsObj->Release();
}
// Cleanup
// ========
pSvc->Release();
pLoc->Release();
pEnumerator->Release();
CoUninitialize();
return 0; // Program successfully completed.
}
已更改的有效行如下：
您会看到SELECT语句看起来与您的C＃ManagementPath构造函数调用相似：
hres = pSvc->ExecQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM Win32_Baseboard WHERE Tag = \"Base Board\""),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
查询正确的属性：
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);
我没有故意整理（有很多机会，例如using namespace std;，应该使用智能指针，等等），但是保持原样以便您可以与原始的MSDN代码。
