判断Vista，2008和9X操作系统

Question

只要判断9x、vista、Windows 2008系统就行了。如果是9x系统，则输出，“这是Windows 9x”。如果是vista系统，则输出，“这是Windows Vista系统。”如果是Windows 2008系统，则输出，“这是Windows 2008系统。”否则输出“不是以上三种系统。”

Answer 2

  是的,用 GetVersionEx 的到一个结构,然后通过结构里的dwMajorVersion 和dwMinorVersion 来进行判断,提供个思路

Answer 3

2L 怎么把我的代码写出来了？：）开句玩笑~~~2L正解。该程序可以分出差不多20种OS，记得当初的一个工程就是用的这个函数。

Answer 4

都没错 ，获取系统信息和 版本结构都可以，基本都是win32API 提供的。
