使用 C++/CLR dll 时 C# 应用程序崩溃

Question

我有 3 个应用程序，一个是输出静态库的 native C++ 应用程序，一个是此静态库的 C++/CLR 包装器，最后一个是使用 C++/CLR 包装器的 C# Windows 窗体应用程序。

当项目为空时，一切都可以正常编译和运行，但是当我在 native C++ 应用程序中向我的类添加一些代码时，我在 C# winforms 应用程序中发生崩溃。

这是错误信息:

A first chance exception of type 'System.IO.FileNotFoundException' occurred in      
WindowsFormsApplication1.exe
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in  
WindowsFormsApplication1.exe

Additional information: Could not load file or assembly 'stenCLR.dll' or one of its 
dependencies. The specified module could not be found.

我确定 stenCLR.dll 在正确的文件夹中。

这是来自 visual studio 的完整错误日志:

Answer 1

我建议看一下 Dependency Walker和 Fusion Log Viewer .

Dependency Walker 会告诉您是否缺少您尝试加载的 DLL。

Fusion Log Viewer 会准确告诉您 DLL 试图从何处加载。

这些通常是调试库加载问题的最简单方法，因为它们使问题变得非常明显:)
