该模块应该包含一个程序集清单

Question

我在c#中有一个使用c ++库和一些dll的项目.当我运行它时效果很好.

该库是Awesomium,包含c ++库和c#包装器

当我从ASP.NET MVC 4项目创建对该项目的引用时,我收到以下错误:

异常详细信息:System.BadImageFormatException:无法加载文件或程序集'file:/// D:\ Projects\Development\ProGamers\GamingSite\bin\avcodec-52.dll'或其依赖项之一.该模块应该包含一个程序集清单.

我试过的事情:

1. 应对dll,但它仍然不起作用(该文件存在).

2. 在GAC中注册它但我在那里遇到了同样的错误.

3. 确保使用.NET Framework 4.0(而不是客户端配置文件)

4. 2个具有相同dll/exe名称的文件导致冲突 - 我没有.

5. 将解决方案的平台更改为AnyCPU/Mixed Platforms.

我发现,我在目标.NET Framework中使用了不同的InstallUtil.我正在构建一个.NET Framework 4.5,同时如果我使用的是.NET Framework 2.0版本,则会出现错误.为我的目标.NET Framework使用正确的InstallUtil,解决了这个问题!

Answer 2

BadImageFormatException根据我的经验,几乎总是与x86和x64编译的程序集有关.听起来你的C++程序集是为x86编译的,你在x64进程上运行.那是对的吗？

而不是AnyCPU/Mixed用作平台.尝试手动将其设置为,x86然后查看它是否会运行.

希望这可以帮助.

首先尝试使用 ILSpy 等反编译器打开该文件，您的 dll 可能已损坏。我在一个在线网站上遇到了这个错误，当我下载 dll 并尝试打开它时，它已损坏，可能是通过 ftp 上传它时发生了一些错误。
