An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module
提问by mj1261829
I am developing a c# application and I get the following error at debug runtime:
我正在开发 ac# 应用程序，在调试运行时出现以下错误：
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module.
Additional information: Could not load file or assembly 'Autodesk.Navisworks.Timeliner.dll' or one of its dependencies. The specified module could not be found.
未知模块中发生类型为“System.IO.FileNotFoundException”的未处理异常。
附加信息：无法加载文件或程序集“Autodesk.Navisworks.Timeliner.dll”或其依赖项之一。指定的模块无法找到。
Autodesk.Navisworks.Timeliner.dll is in the debug folder of the application. I have repaired the .net framework (version 4) but it did not resolve it. Any ideas on how to resolve this issue? Thanks.
Autodesk.Navisworks.Timeliner.dll 位于应用程序的调试文件夹中。我已经修复了 .net 框架（版本 4）但它没有解决它。有关如何解决此问题的任何想法？谢谢。

First check - is the working directory the directory that the application is running in:
首先检查 - 工作目录是应用程序运行的目录：
- Right-click on your project and select Properties.
- Click the Debug tab.
- Confirm that the Working directory is either empty or equal to the bin\debug directory.
- 右键单击您的项目并选择属性。
- 单击调试选项卡。
- 确认工作目录为空或等于 bin\debug 目录。
If this isn't the problem, then ask if Autodesk.Navisworks.Timeliner.dll is requiring another DLL which is not there.
If Timeliner.dll is not a .NET assembly, you can determine the required imports using the command utility DUMPBIN.
如果这不是问题，则询问 Autodesk.Navisworks.Timeliner.dll 是否需要另一个不存在的 DLL。如果 Timeliner.dll 不是 .NET 程序集，您可以使用命令实用程序确定所需的导入DUMPBIN。
dumpbin /imports Autodesk.Navisworks.Timeliner.dll
If it is a .NET assembly, there are a number of tools that can check dependencies.
如果是 .NET 程序集，则有许多工具可以检查依赖项。

If you are running on a 64 bit system and trying to load a 32 bit dll you need to compile your application as 32 bit instead of any cpu. If you are not doing this it behaves exactly as you describe.
如果您在 64 位系统上运行并尝试加载 32 位 dll，您需要将应用程序编译为 32 位而不是任何 cpu。如果您不这样做，它的行为与您描述的完全一样。
If that isn't the case use Dependency Walkerto verify that the dll has its required dependencies.
如果不是这种情况，请使用Dependency Walker来验证 dll 是否具有其所需的依赖项。

For me it was occurring in a .net project and turned out to be something to do with my Visual Studio installation. I downloaded and installed the latest .net core sdk separately and then reinstalled VS and it worked.
对我来说，它发生在 .net 项目中，结果与我的 Visual Studio 安装有关。我单独下载并安装了最新的 .net core sdk，然后重新安装了 VS，它工作正常。
