Windows 提供了一组API calls for retrieving the version information来自可执行文件。以下代码片段应该可以帮助您入门。

bool GetVersionInfo(
    LPCTSTR filename,
    int &major,
    int &minor,
    int &build,
    int &revision)
{
    DWORD   verBufferSize;
    char    verBuffer[2048];

    //  Get the size of the version info block in the file
    verBufferSize = GetFileVersionInfoSize(filename, NULL);
    if(verBufferSize > 0 && verBufferSize <= sizeof(verBuffer))
    {
        //  get the version block from the file
        if(TRUE == GetFileVersionInfo(filename, NULL, verBufferSize, verBuffer))
        {
            UINT length;
            VS_FIXEDFILEINFO *verInfo = NULL;

            //  Query the version information for neutral language
            if(TRUE == VerQueryValue(
                verBuffer,
                _T("\\"),
                reinterpret_cast<LPVOID*>(&verInfo),
                &length))
            {
                //  Pull the version values.
                major = HIWORD(verInfo->dwProductVersionMS);
                minor = LOWORD(verInfo->dwProductVersionMS);
                build = HIWORD(verInfo->dwProductVersionLS);
                revision = LOWORD(verInfo->dwProductVersionLS);
                return true;
            }
        }
    }

    return false;
}
