如何检查编程的托管程序集是否是86，64或值为anycpu？ [英] How to check programmatically whether a managed assembly is x86, x64 or AnyCPU?

问题描述

我需要确定编程程序集是否是86，64或值为anycpu？有几乎相同的<一href="http://stackoverflow.com/questions/270531/how-to-determine-if-a-net-assembly-was-built-for-x86-or-x64">question,但是该解决方案，它提供了

I need to determine programmatically whether an assembly is x86, x64 or AnyCPU? There is an almost identical question, but the solution that it provides

Assembly assembly = Assembly.LoadFrom(fileName);
PortableExecutableKinds peKind;
ImageFileMachine imageFileMachine;
assembly.ManifestModule.GetPEKind(out peKind, out imageFileMachine);

试图从32位进程（反之亦然）加载64位汇编时会失败。

fails when trying to load a 64-bit assembly from a 32-bit process (and vice versa).

是否有编程方式找出程序集的编译类型万无一失的方法是什么？

Is there a foolproof way of programmatically finding out the compilation type of an assembly?

编辑：基于@BenVoigt的建议，我创建了一个<一个href="http://www.angryhacker.com/blog/archive/2012/03/03/how-to-determine-whether-an-assembly-is-32-bit-64.aspx"相对=nofollow>小的命令行实用程序来检查DLL是否被托管与否，以及是否其在x86 / x64 /值为anycpu。我希望有人认为它有用。

Based on @BenVoigt suggestion, I created a small command line utility that checks whether the DLL is managed or not and whether its x86/x64/AnyCPU. I hope someone finds it useful.

但答案是不完整的，这表明使用 Assembly.LoadFrom 。这是一个可怕的想法，因为它将运行从组装code，此外，如果失败的位数不匹配的过程。

But the answers are incomplete, suggesting use of Assembly.LoadFrom. That's a terrible idea, since it will run code from the assembly, in addition to failing if the bitness doesn't match your process.

相反，你应该使用<一个href="http://msdn.microsoft.com/en-us/library/system.reflection.assembly.reflectiononlyloadfrom.aspx"><$c$c>Assembly.ReflectionOnlyLoadFrom.这使您可以读取的元数据，而无需实际加载任何code，因此没有必要为架构是正确的。

Instead, you should use Assembly.ReflectionOnlyLoadFrom. This lets you read the metadata without actually loading any code, and therefore there's no need for the architecture to be correct.
