为什么Windows 10中kernel32.dll上的GetFileVersionInfo返回版本6.2? [英] Why does GetFileVersionInfo on kernel32.dll in Windows 10 return version 6.2?

问题描述

我正在尝试检索kernel32.dll版本以执行Windows版本检查.但是，由于某些原因，即使kernel32.dll的版本(如文件属性中所示)为10.0.10586.0，返回的版本仍为:6.2.10586.0 怎么来的?

I am trying to retrieve kernel32.dll version in order to perform a Windows version check. Yet, for some reason, even though kernel32.dll's version (as seen in file properties) is 10.0.10586.0, the returned version is: 6.2.10586.0 how come?

    DWORD dwDummy;
    DWORD dwFVISize = GetFileVersionInfoSize(lpszFilePath, &dwDummy);
    LPBYTE lpVersionInfo = new BYTE[dwFVISize];
    if (GetFileVersionInfo(lpszFilePath, 0, dwFVISize, lpVersionInfo) == 0)
    {
        return FALSE;
    }

    UINT uLen;
    VS_FIXEDFILEINFO *lpFfi;
    BOOL bVer = VerQueryValue(lpVersionInfo, L"\\", (LPVOID *)&lpFfi, &uLen);

    if (!bVer || uLen == 0)
    {
        return FALSE;
    }
    DWORD dwFileVersionMS = lpFfi->dwFileVersionMS;
    DWORD dwFileVersionLS = lpFfi->dwFileVersionLS;
    delete[] lpVersionInfo;

    DWORD dwLeftMost = HIWORD(dwFileVersionMS);
    DWORD dwSecondLeft = LOWORD(dwFileVersionMS);
    DWORD dwSecondRight = HIWORD(dwFileVersionLS);
    DWORD dwRightMost = LOWORD(dwFileVersionLS);

推荐答案

您正在从此任务的版本信息中读取错误的字段.代替dwFileVersionMS和dwFileVersionLS，使用dwProductVersionMS和dwProductVersionLS.

You are reading the wrong fields from the version information for this task. Instead of dwFileVersionMS and dwFileVersionLS use dwProductVersionMS and dwProductVersionLS.

文件版本字段受supportedOS兼容性问题的影响.那就是它们的值取决于在应用程序清单中声明的​​supportedOS级别.另一方面，产品版本字段不依赖清单.

The file version fields are subject to supportedOS compatibility issues. That is their values depend on the supportedOS levels declared in your application manifest. On the other hand the product version fields do not depend on the manifest.
