我有一个任意的。net程序集列表。
我需要以编程方式检查每个DLL是否为x86构建(而不是x64或任何CPU)。这可能吗?

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
@echo off
echo.
echo Target architecture for all exes and dlls:
echo.
REM For each exe and dll in this directory and all subdirectories...
for %%a in (.exe, .dll) do forfiles /s /m *%%a /c "cmd /c echo @relpath" > testfiles.txt
for /f %%b in (testfiles.txt) do (
REM Dump corflags results to a text file
corflags /nologo %%b > corflagsdeets.txt
REM Parse the corflags results to look for key markers
findstr /C:"PE32+">nul .\corflagsdeets.txt && (
REM `PE32+` indicates x64
echo %%~b = x64
) || (
REM pre-v8 Windows SDK listed only "32BIT" line item,
REM newer versions list "32BITREQ" and "32BITPREF" line items
findstr /C:"32BITREQ : 0">nul /C:"32BIT : 0" .\corflagsdeets.txt && (
REM `PE32` and NOT 32bit required indicates Any CPU
echo %%~b = Any CPU
) || (

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。”
检查.NET程序集的目标平台的另一种方法是使用.NET Reflector检查程序集…
@ # ~ #€~ !我刚刚意识到新版本不是免费的!因此,更正一下,如果你有一个。net reflector的免费版本,你可以用它来检查目标平台。
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:
还有一种方法是在DLL上使用Visual Studio工具中的dumpbin,并寻找适当的输出:
dumpbin.exe /HEADERS <your DLL file path>
FILE HEADER VALUE
14C machine (x86)
4 number of sections
5885AC36 time date stamp Mon Jan 23 12:39:42 2017
0 file pointer to symbol table
0 number of symbols
E0 size of optional header
2102 characteristics
Executable
32 bit word machine
DLL
注意:上面的输出是一个32位DLL文件
dumpbin.exe的一个更有用的选项是/EXPORTS。它将显示DLL文件公开的函数
dumpbin.exe /EXPORTS <PATH OF THE DLL FILE>
