BadImageFormatException during .Net assembly load issue
I am trying to run a exe file which loads a assembly and extracts its version. The file is working fine on win xp but while running it on win 7 it crashes giving the following exception.
我正在尝试运行一个加载程序集并提取其版本的 exe 文件。该文件在 win xp 上运行良好，但在 win 7 上运行时崩溃，出现以下异常。
Unhandled Exception: System.BadImageFormatException: Could not load file or asse

an incorrect format.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\M
icrosoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure lo
gging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus
ion!EnableLog].
Has anybody faced this problem? What could be the probable solution to this problem?
有没有人遇到过这个问题？这个问题的可能解决方案是什么？

This can have several causes, the most likely is that you are trying to load a 32bit managed dll on a 64 bit machine, or vice versa.
这可能有多种原因，最有可能的原因是您尝试在 64 位计算机上加载 32 位托管 dll，反之亦然。
It can also mean that a dll you are dynamically loading is not a native dll, or that the dll file is corrupted.
这也可能意味着您正在动态加载的 dll 不是本机 dll，或者 dll 文件已损坏。
It may mean that you have a dll which is using a higher version of the .Net framework than some other dll that is using it, if you rebuilt a particular component with a different version for example.
这可能意味着您的 dll 使用的 .Net 框架版本比其他使用它的 dll 版本更高，例如，如果您使用不同版本重建特定组件。
This questioncovers similar ground, as does this onewhich also suggests a way to force your 64bit app to run in 32bit mode so it can load the 32bit dependency.

Please check if you are running a 64bit Windows and the dll ist 32bit ONLY (sometimes special versions for 64bit Windows are available)
请检查您是否正在运行 64 位 Windows 并且 dll 仅 32 位（有时可以使用 64 位 Windows 的特殊版本）
