如何查看vs2010是32还是64_...dll是32位还是64位

打开cmd：

cd C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin

运行vcvars32.bat?

再次输入以下命令：

dumpbin /headers D:\ap8ae8.dll

将会看到以下结果：

为什么80%的码农都做不了架构师？>>> ??

在VC2010中通过platform选择32位还是64位编译时，可以通过下面的条件编译指令来判断：

[cpp] view plain copy

?

//?32位编译??#ifdef?_M_IX86??#pragma?comment(lib,"QDPay_mt.lib")??#endif?//?_M_IX86??//?64位编译??#ifdef?_M_X64??#pragma?comment(lib,"QDPay_mt64.lib")??#endif?//?_M_X64??

?

参见MSDN:https://www.sxzhongrui.com/en-us/library/b0084kay.aspx

相关的预定义宏：

?

_M_IX86 : 32bit处理器

_M_AMD64 : 64bit AMD处理器 (VC2008以前)

_M_X64 : 64bit AMD and Intel处理器(VC2008及以后),

_M_IX64 : 64bit Itanium处理器

?

_WIN32 : Defined for both 32bit and 64bit processor

_WIN64 : Defined for 64bit processor

以vs2010为例，进入以下目录

C:\Program Files\Microsoft Visual Studio 10.0\VC\bin

打开控制台窗口，运行vcvars32.bat，设置vs运行环境

输入以下命令进行查询

dumpbin /headers path

其中path为lib或dll文件的路径，并且加上该文件的名字。

输出的信息即可查询文件位数。
