How to Tell if a .NET Assembly Was Compiled as x86, x64 or Any CPU
提问by Tim Long
What's the easiest way to discover (without access to the source project) whether a .NET assembly DLL was compiled as 'x86', 'x64' or 'Any CPU'?
发现（无需访问源项目）.NET 程序集 DLL 是否编译为“x86”、“x64”或“Any CPU”的最简单方法是什么？
Update: A command-line utility was sufficient to meet my immediate needs, but just for the sake of completeness, if someone wants to tell me how to do it programmatically then that would be of interest too, I'm sure.
更新：命令行实用程序足以满足我的直接需求，但为了完整起见，如果有人想告诉我如何以编程方式执行此操作，那么这也很有趣，我敢肯定。

If you just want to find this out on a given dll, then you can use the CorFlagstool that is part of the Windows SDK:
如果您只想在给定的 dll 上找到这一点，那么您可以使用Windows SDK 中的CorFlags工具：
CorFlags.exe assembly.dll
If you want to do it using code, take a look at the GetPEKindmethod of the Moduleclass:
如果你想用代码来做，看看Module类的GetPEKind方法：
Assembly assembly = Assembly.LoadFrom("path to dll");
PortableExecutableKinds peKind;
ImageFileMachine imageFileMachine;
assembly.ManifestModule.GetPEKind(out peKind, out imageFileMachine)
You then need to examine the peKindto check its value. See the MSDN docsfor PortableExecutableKindsfor more info.
然后，您需要检查peKind以检查其值。请参阅MSDN文档的PortableExecutableKinds更多信息。

Thanks Adrian! I've rewritten the snippet in PowerShell so I could use it on the server.
谢谢阿德里安！我已经在 PowerShell 中重写了该代码段，以便可以在服务器上使用它。
#USAGE #1
# Get-Bitness (dir *.dll | select -first 1)
#USAGE #2
# Get-Bitness "C:\vs\projects\bestprojectever\bin\debug\mysweetproj.dll"
function Get-Bitness([System.IO.FileInfo]$assemblyFile)
{
$peKinds = new-object Reflection.PortableExecutableKinds
$imageFileMachine = new-object Reflection.ImageFileMachine
$a = [Reflection.Assembly]::LoadFile($assemblyFile.Fullname)
$a.ManifestModule.GetPEKind([ref]$peKinds, [ref]$imageFileMachine)
return $peKinds
}

Thanks Adrian and Peter! Here's a modified version of Peter's Get-Bitness that 1) takes a list of files to examine from the pipeline, and 2) doesn't die it if looks at a non-.NET DLL (e.g. if it looks at certain C++ DLLs):
谢谢阿德里安和彼得！这是 Peter's Get-Bitness 的一个修改版本，它 1) 从管道中获取要检查的文件列表，并且 2) 如果查看非 .NET DLL（例如，如果它查看某些 C++ DLL），它不会死：
# example usage: dir *.exe,*.dll | Get-PEKind
function Get-PEKind {
Param(
[Parameter(Mandatory=$True,ValueFromPipeline=$True)]
[System.IO.FileInfo]$assemblies
)
Process {
foreach ($assembly in $assemblies) {
$peKinds = new-object Reflection.PortableExecutableKinds
$imageFileMachine = new-object Reflection.ImageFileMachine
try
{
$a = [Reflection.Assembly]::LoadFile($assembly.Fullname)
$a.ManifestModule.GetPEKind([ref]$peKinds, [ref]$imageFileMachine)
}
catch [System.BadImageFormatException]
{
$peKinds = [System.Reflection.PortableExecutableKinds]"NotAPortableExecutableImage"
}
$o = New-Object System.Object
$o | Add-Member -type NoteProperty -name File -value $assembly
$o | Add-Member -type NoteProperty -name PEKind -value $peKinds
Write-Output $o
}
}
}
I'm new to PowerShell, so this may not be an example of best practices.
我是 PowerShell 的新手，因此这可能不是最佳实践的示例。
Alternatively, according to https://stackoverflow.com/a/4719567/64257there may also be a handy Get-PEHeader cmdlet in the PowerShell Community Extensions.
或者，根据https://stackoverflow.com/a/4719567/64257，PowerShell Community Extensions 中也可能有一个方便的 Get-PEHeader cmdlet 。

C# snippet, based on the Powershell answers:
C# 片段，基于 Powershell 答案：
var modules = assembly.GetModules();
var kinds = new List<PortableExecutableKinds>();
var images = new List<ImageFileMachine>();
foreach (var module in modules)
{
PortableExecutableKinds peKinds;
ImageFileMachine imageFileMachine;
module.GetPEKind(out peKinds, out imageFileMachine);
kinds.Add(peKinds);
images.Add(imageFileMachine);
}
var distinctKinds = kinds.Distinct().ToList();
var distinctImages = images.Distinct().ToList();
