C++ Windows 8 下的 GetVersionEx

GetVersionEx under Windows 8

提问by ahmd0

I'm writing a C++ code to determine what OS it is running on. I use GetVersionEx()API to do that, and this codeas a tutorial, but it doesn't seems to handle Windows 8. Does anyone know how to fix it to run under Windows 8?

我正在编写一个 C++ 代码来确定它在什么操作系统上运行。我使用GetVersionEx()API 来做到这一点，并将此代码作为教程，但它似乎不能处理 Windows 8。有谁知道如何修复它以在 Windows 8 下运行？

According to several comments in the MSDN forums and this articlethe version number for Windows 8 is 6.2

根据 MSDN 论坛和本文中的几条评论，Windows 8 的版本号为 6.2

This is the sample code updated and tested in Windows 8 Developer Preview

OK, I was hoping someone has done this already ... but, I guess not, so here you go:

好的，我希望有人已经这样做了......但是，我想不是，所以你去吧：

//OSVERSIONINFO for GetVersionEx returns:
dwMajorVersion = 6;
dwMinorVersion = 2;
wProductType = 1;

//GetProductInfo returns:
dwType = 0x4A;   //Not documented yet???

PS. I don't have VS IDE installed there. Had to make a small app to get those...

附注。我没有在那里安装 VS IDE。必须制作一个小应用程序才能获得这些...

According to this MSDN page, it is actually recommended to use the Version Helper functions instead of GetVersionInfoExto determine the running Windows version. As described on the GetVersionExpage, that API may disappear in the future.

根据this MSDN page，实际上建议使用Version Helper功能而不是GetVersionInfoEx确定正在运行的Windows版本。如GetVersionEx页面所述，该 API 将来可能会消失。

Another possible method for basic (major, minor) validation of the system but not in depth product details is to check the version of a core system file, example kernel32.dll.

另一种对系统进行基本（主要、次要）验证但不深入产品细节的可能方法是检查核心系统文件的版本，例如 kernel32.dll。
