【中文标题】获取 Windows 体系结构（32/64 位版本）【英文标题】：Getting Architecture of Windows (32/64 bit version) 【发布时间】：2011-03-11 22:19:39 【问题描述】：我遇到了一个小问题：
我想得到操作系统的架构，问题是我的编程语言不支持这些功能。因此，我需要从 Windows dll（如 kernel32.dll）中读取此信息
我确实尝试使用函数GetNativeSystemInfo/GetVersionEx/GetSystemInfo 获取信息。
不幸的是，我无法获得架构：/
是否有其他函数可以读取任何 Windows dll 中的体系结构？ （它不需要是kernel32它可以是任何dll但它必须存在于win xp+中）
作为信息：我正在使用 Gupta (SQLWindows/Team devoloper)
编辑1：
typedef struct _SYSTEM_INFO
union
DWORD dwOemId;
struct
WORD wProcessorArchitecture;
WORD wReserved;
;
;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
SYSTEM_INFO;
这是来自MSDN 的信息，我尝试使用 10 和 12 参数调用此函数 （Gupta 不支持结构）。 在 32 位上我得到：alt text http://img714.imageshack.us/img714/1954/32bit.gif
在 64 位上我得到：alt text http://img691.imageshack.us/img691/8978/64bit.gif
我每次都会在 32 位上获得 0 OemID 吗？或者更好的是在 64 位版本的 windows 上填充 OemID everytiem？
谢谢帮助！！
问候 奥罗

【讨论】：
【参考方案2】：GetNativeSystemInfo 绝对是要使用的功能。如果您的应用是原生 64 位应用，GetNativeSystemInfo 与 GetSystemInfo 相同；否则，如果它在 WOW64 下运行，它将返回真实的系统属性，即使它是在模拟的 32 位环境中运行的。
GetNativeSystemInfo 填充了一个SYSTEM_INFO 结构，其中的wProcessorArchitecture 成员告诉您系统是32 位（可能是PROCESSOR_ARCHITECTURE_INTEL）还是64 位（可能是PROCESSOR_ARCHITECTURE_AMD64）。
如果你的语言没有这个 Win API 函数的包装器，要使用它，你可以像往常一样使用LoadLibrary 和GetProcAddress，当然你需要定义SYSTEM_INFO 结构。
更新
我会定义
typedef struct _SYSTEM_INFO
WORD wProcessorArchitecture;
WORD wReserved;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
SYSTEM_INFO;
然后wProcessorArchitecture = 0 在（通用）32 位系统上，wProcessorArchitecture = 9 在（通用）64 位系统上。这些只是常量PROCESSOR_ARCHITECTURE_INTEL 和PROCESSOR_ARCHITECTURE_AMD64，分别。这些是常见的 32 位和 64 位架构。 PROCESSOR_ARCHITECTURE_IA64 = 6 稍微不常见，PROCESSOR_ARCHITECTURE_UNKNOWN = 65535 肯定也是如此。
更新
是的，我看到了你的问题。在 C 中，union 表示您一次选择 一个 选项。也就是说，结构要么是
DWORD dwOemId;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
或
WORD wProcessorArchitecture;
WORD wReserved;
DWORD dwPageSize;
LPVOID lpMinimumApplicationAddress;
LPVOID lpMaximumApplicationAddress;
DWORD_PTR dwActiveProcessorMask;
DWORD dwNumberOfProcessors;
DWORD dwProcessorType;
DWORD dwAllocationGranularity;
WORD wProcessorLevel;
WORD wProcessorRevision;
因为一个 DWORD 包含与两个字 (2×2) 一样多的字节 (4)，所以替代方案只是寻址（和命名）整个结构的数据的两种方式。在我们的例子中，我们更感兴趣的是 wProcessorArchitecture 词，而不是 wProcessorArchitecture 的扩充 dwOemId 和完全无趣的 wReserved 词。
【讨论】：
看起来我不能使用 GetNativeSystemInfo 因为它不清晰可读。有没有办法从注册表中读取它？我不确定 HKLM\Sorftware\Microsoft\Windows NT\currentVersion\BuildLabEx 是否保存... 啊，现在它完美运行了：D 是的，问题是我确实以错误的方式调用了 Kernel32 中的函数......谢谢你的帮助！以上是关于获取 Windows 体系结构（32/64 位版本）的主要内容，如果未能解决你的问题，请参考以下文章
