C++ 如何以编程方式获取 DLL 或 EXE 文件的版本？

How do I programmatically get the version of a DLL or EXE file?

提问by JSB????

I need to get the product version and file version for a DLL or EXE file using Win32 native APIs in C or C++. I'm notlooking for the Windows version, but the version numbers that you see by right-clicking on a DLL file, selecting "Properties", then looking at the "Details" tab. This is usually a four-part dotted version number x.x.x.x.

我需要使用 C 或 C++ 中的 Win32 本机 API 获取 DLL 或 EXE 文件的产品版本和文件版本。我不是在寻找 Windows 版本，而是通过右键单击 DLL 文件，选择“属性”，然后查看“详细信息”选项卡来查看版本号。这通常是一个由四部分组成的虚线版本号 xxxx

You would use the GetFileVersionInfoAPI.

您将使用GetFileVersionInfoAPI。

See Using Version Informationon the MSDN site.

请参阅MSDN 站点上的使用版本信息。

Sample:

样本：

DWORD  verHandle = 0;
UINT   size      = 0;
LPBYTE lpBuffer  = NULL;
DWORD  verSize   = GetFileVersionInfoSize( szVersionFile, &verHandle);

if (verSize != NULL)
{
    LPSTR verData = new char[verSize];

    if (GetFileVersionInfo( szVersionFile, verHandle, verSize, verData))
    {
        if (VerQueryValue(verData,"\",(VOID FAR* FAR*)&lpBuffer,&size))
        {
            if (size)
            {
                VS_FIXEDFILEINFO *verInfo = (VS_FIXEDFILEINFO *)lpBuffer;
                if (verInfo->dwSignature == 0xfeef04bd)
                {

                    // Doesn't matter if you are on 32 bit or 64 bit,
                    // DWORD is always 32 bits, so first two revision numbers
                    // come from dwFileVersionMS, last two come from dwFileVersionLS
                    TRACE( "File Version: %d.%d.%d.%d\n",
                    ( verInfo->dwFileVersionMS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionMS >>  0 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >>  0 ) & 0xffff
                    );
                }
            }
        }
    }
    delete[] verData;
}

All these solutions did not work properly (with my system). I found out that each of the four parts of the version number are saved as a 16-bit value.

所有这些解决方案都无法正常工作（使用我的系统）。我发现版本号的四个部分中的每一个都保存为一个 16 位值。

The first two numbers are saved in the 32-bit DWORD dwFileVersionMS, and the second two in dwFileVersionLS. So I edited your code at the output section like this:

前两个数字保存在 32 位 DWORD dwFileVersionMS 中，后两个数字保存在 dwFileVersionLS 中。所以我在输出部分编辑了你的代码，如下所示：

    TRACE( "File Version: %d.%d.%d.%d\n",
        ( pFileInfo->dwFileVersionMS >> 16 ) & 0xffff,
        ( pFileInfo->dwFileVersionMS >>  0 ) & 0xffff,
        ( pFileInfo->dwFileVersionLS >> 16 ) & 0xffff,
        ( pFileInfo->dwFileVersionLS >>  0 ) & 0xffff
        );

And it works perfectly. The output is formatted like on my system:

它完美地工作。输出的格式类似于我的系统：

major.minor.build.revision

主要.次要.build.revision

You get this information using the version information APIs. Here is a sample:

您可以使用版本信息 API获取此信息。这是一个示例：

void PrintFileVersion( TCHAR *pszFilePath )
{
    DWORD               dwSize              = 0;
    BYTE                *pbVersionInfo      = NULL;
    VS_FIXEDFILEINFO    *pFileInfo          = NULL;
    UINT                puLenFileInfo       = 0;

    // Get the version information for the file requested
    dwSize = GetFileVersionInfoSize( pszFilePath, NULL );
    if ( dwSize == 0 )
    {
        printf( "Error in GetFileVersionInfoSize: %d\n", GetLastError() );
        return;
    }

    pbVersionInfo = new BYTE[ dwSize ];

    if ( !GetFileVersionInfo( pszFilePath, 0, dwSize, pbVersionInfo ) )
    {
        printf( "Error in GetFileVersionInfo: %d\n", GetLastError() );
        delete[] pbVersionInfo;
        return;
    }

    if ( !VerQueryValue( pbVersionInfo, TEXT("\"), (LPVOID*) &pFileInfo, &puLenFileInfo ) )
    {
        printf( "Error in VerQueryValue: %d\n", GetLastError() );
        delete[] pbVersionInfo;
        return;
    }

    // pFileInfo->dwFileVersionMS is usually zero. However, you should check
    // this if your version numbers seem to be wrong

    printf( "File Version: %d.%d.%d.%d\n",
        ( pFileInfo->dwFileVersionLS >> 24 ) & 0xff,
        ( pFileInfo->dwFileVersionLS >> 16 ) & 0xff,
        ( pFileInfo->dwFileVersionLS >>  8 ) & 0xff,
        ( pFileInfo->dwFileVersionLS >>  0 ) & 0xff
        );

    // pFileInfo->dwProductVersionMS is usually zero. However, you should check
    // this if your version numbers seem to be wrong.

    printf( "Product Version: %d.%d.%d.%d\n",
        ( pFileInfo->dwProductVersionLS >> 24 ) & 0xff,
        ( pFileInfo->dwProductVersionLS >> 16 ) & 0xff,
        ( pFileInfo->dwProductVersionLS >>  8 ) & 0xff,
        ( pFileInfo->dwProductVersionLS >>  0 ) & 0xff
        );
}

This code shows the file version numbers correctly.

此代码正确显示文件版本号。

( pFileInfo->dwFileVersionMS >> 16 ) & 0xff,
( pFileInfo->dwFileVersionMS >> 0 ) & 0xff,
( pFileInfo->dwFileVersionLS >>  16 ) & 0xff,
( pFileInfo->dwFileVersionLS >>  0 ) & 0xff);

Found these articles...sorry, but I don't have direct experience with how to do this using native APIs, so I deferred to an Internet search:

找到了这些文章……抱歉，我没有直接使用本机 API 执行此操作的经验，因此我推迟到 Internet 搜索：

• C++: Determining the version number of a DLL or Executable
• VB (probably version 6): How to Use Functions in VERSION.DLL

• C++：确定 DLL 或可执行文件的版本号
• VB（可能是第 6 版）：如何使用 VERSION.DLL 中的函数

Hope these help!

希望这些有帮助！

The easiest way is to use the GetFileVersionInfoExor GetFileVersionInfoAPI functions.

最简单的方法是使用GetFileVersionInfoEx或GetFileVersionInfoAPI 函数。

You can also do it from within your application resources as explained here.

您也可以按照此处的说明在应用程序资源中执行此操作。

Since none of the answers mention it... I found out that you have to make different calculations depending on if you're running on 32- or 64-bit systems. That's why you find that certain answers in this question work for you, and others do not.

由于没有一个答案提到它......我发现你必须根据你是在 32 位系统还是 64 位系统上运行而进行不同的计算。这就是为什么您会发现这个问题中的某些答案适合您，而其他答案则不适合。

Here's a sample implementation I use:

这是我使用的示例实现：

if(IsWow64())
{
        // 64 bit build
        major =     (verInfo->dwProductVersionMS >> 16) & 0xffff;
        minor =     (verInfo->dwProductVersionMS >>  0) & 0xffff;
        revision =  (verInfo->dwProductVersionLS >> 16) & 0xffff;
        build =     (verInfo->dwProductVersionLS >>  0) & 0xffff;
} 
else
{
        // 32 bit build
        major =     HIWORD(verInfo->dwProductVersionMS);
        minor =     LOWORD(verInfo->dwProductVersionMS);
        revision =  HIWORD(verInfo->dwProductVersionLS);
        build =     LOWORD(verInfo->dwProductVersionLS);
}

And the implementation of IsWow64 (not mine):

以及 IsWow64 的实现（不是我的）：

typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL);
LPFN_ISWOW64PROCESS fnIsWow64Process;

BOOL IsWow64()
{
    BOOL bIsWow64 = FALSE;

    //IsWow64Process is not available on all supported versions of Windows.
    //Use GetModuleHandle to get a handle to the DLL that contains the function
    //and GetProcAddress to get a pointer to the function if available.

    fnIsWow64Process = (LPFN_ISWOW64PROCESS) GetProcAddress(
        GetModuleHandle(TEXT("kernel32")),"IsWow64Process");

    if(NULL != fnIsWow64Process)
    {
        if (!fnIsWow64Process(GetCurrentProcess(),&bIsWow64))
        {
            // Handle error...
        }
    }
    return bIsWow64;
}
