澄清一下，CorFlags.exe是. net Framework SDK的一部分。我的机器上有开发工具，对我来说，确定DLL是否仅为32位的最简单方法是:

打开Visual Studio命令提示符(Windows系统:菜单开始/程序/Microsoft Visual Studio/Visual Studio工具/Visual Studio 2008命令提示符) CD到包含有关DLL的目录 像这样运行corflags: corflags MyAssembly.dll

你会得到这样的输出:

Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  3.5.21022.8

Version   : v2.0.50727
CLR Header: 2.5
PE        : PE32
CorFlags  : 3
ILONLY    : 1
32BIT     : 1
Signed    : 0

根据评论，上述标志的解读如下:

任意CPU: PE = PE32, 32BIT = 0 x86: PE = PE32, 32BIT = 1 64位:PE = PE32+， 32BIT = 0

JetBrains的DotPeek提供了一个快速简单的方法来查看msil(任何CPU)， x86和x64:

我克隆了一个超级方便的工具，它为Windows资源管理器中的程序集添加了一个上下文菜单项，以显示所有可用的信息:
