Troubleshooting BadImageFormatException

我正在尝试编译我的解决方案，但收到有关 dll 的错误消息。我在另一个解决方案的 bin 文件夹中复制了那个 dll，但它没有编译它（第二个解决方案与那个 dll 无关，它不使用它）

我收到的错误是以下错误：

Server Error in '/browsertest1' Application.

Could not load file or assembly 'KT.AF.Engine.Core' or one of its dependencies. An attempt was made to load a program with an incorrect format.

描述：An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'KT.AF.Engine.Core' could not be loaded.


WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

看起来 DLL 文件已针对不同于您的解决方案构建的系统架构进行编译。

确保两件事：

您的项目设置为构建为“任何 CPU” - 这可以在 Visual Studio 的项目属性中找到。

IIS 已设置为允许在您的应用程序池中使用 32 位应用程序。
