推荐答案

我想要使用操作系统版本，但该属性没有给我任何关于操作系统套件或产品类型的信息。这就是我这样做的原因

方式。 Nicholas Paldino [.NET / C＃MVP]写道：

Sabin，

为什么不在Environment类上使用静态OSVersion属性？它应该给你很多你想要的东西。

如果那不是你想要你想要的，你试过在定义吗？ rel =nofollowhref =http://www.pinvoke.net？ target =_ blank> http://www.pinvoke.net？
希望这会有所帮助。

Sabin,

Why not use the static OSVersion property on the Environment class? It
should give you a good deal of what you want.

If that doesn''t give you want you want, have you tried looking for this
definition on http://www.pinvoke.net?

Hope this helps.

我做了一些调试，似乎GetVersionEx总是

返回false。谁能告诉我什么？

I''ve made some debugging and it seems that the GetVersionEx always
returns false. Can anyone tell me whay?

你做了我发布的更改吗？

Did you made the changes I posted?
