下面是一个批处理文件，它将针对当前工作目录和所有子目录中的所有DLL文件和EXE文件运行corflags.exe，解析结果并显示每个目标体系结构。

Depending on the version of corflags.exe that is used, the line items in the output will either include 32BIT, or 32BITREQ (and 32BITPREF). Whichever of these two is included in the output is the critical line item that must be checked to differentiate between Any CPU and x86. If you are using an older version of corflags.exe (pre Windows SDK v8.0A), then only the 32BIT line item will be present in the output, as others have indicated in past answers. Otherwise 32BITREQ and 32BITPREF replace it.

这假设corflags.exe在%PATH%. exe文件中。确保这一点的最简单方法是使用开发人员命令提示符。或者，您也可以从默认位置复制它。

如果下面的批处理文件是针对一个非托管DLL或EXE文件运行的，它将错误地显示为x86，因为Corflags.exe的实际输出将是一个类似于:

CF008:指定的文件没有有效的托管头

试着在CodePlex中使用这个项目中的CorFlagsReader。它没有对其他程序集的引用，可以按原样使用。

我喜欢ILSpy工具。它不仅显示了架构，还显示了目标框架:

// linq2db, Version=3.0.0.0, Culture=neutral, PublicKeyToken=e41013125f9e410a
// Global type: <Module>
// Architecture: AnyCPU (64-bit preferred)
// Runtime: v4.0.30319
// This assembly is signed with a strong name key.
// This assembly was compiled using the /deterministic option.
// Hash algorithm: SHA1

因此，可以确定它是。net Core 2.1， .NET Framework 4.6或任何其他版本:

cfeduke注意到调用GetPEKind的可能性。在PowerShell中进行这个操作可能会很有趣。

例如，下面是可以使用的cmdlet代码:https://stackoverflow.com/a/16181743/64257

另外，在https://stackoverflow.com/a/4719567/64257网站上提到“PowerShell社区扩展中也有Get-PEHeader cmdlet，可以用来测试可执行图像。”

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
Copyright (c) Microsoft Corporation.  All rights reserved.

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

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
