如何找到，如果本机的DLL文件编译为64位或x86？ [英] How to find if a native DLL file is compiled as x64 or x86?

问题描述

我想，以确定是否本地组件符合从有管理的code应用程序的x64或x86（ C＃）。

I want to determine if a native assembly is complied as x64 or x86 from a managed code application (C#).

我认为，必须在某个地方的PE头，因为操作系统加载器需要知道这个信息，但我怎么也找不到它。当然，我preFER做到在管理code，但如果有必要，我可以用本地C ++。

I think it must somewhere in the PE header since the OS loader needs to know this information, but I couldn't find it. Of course I prefer to do it in managed code, but if it necessary, I can use native C++.

推荐答案

您可以使用的 DUMPBIN 了。使用 /头或 /所有标记和它的第一个文件头上市。

You can use DUMPBIN too. Use the /headers or /all flag and its the first file header listed.

dumpbin /headers cv210.dll
