Question

我有3个应用程序，一个是本机C ++应用程序，它输出一个静态库，一个是这个静态库的C ++ / CLR包装器，最后是一个使用C ++ / CLR包装器的C＃windows窗体应用程序。

当项目为空时，一切都编译并运行正常但是当我在本机C ++应用程序中向我的类添加一些代码时，我在C＃winforms应用程序中崩溃了。

以下是错误消息：

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位于正确的文件夹中。

以下是visual studio的完整错误日志：

Answer 1

我建议您查看Dependency Walker和Fusion Log Viewer。

Dependency Walker会告诉您是否有任何DLL正在尝试加载的DLL丢失。

Fusion Log Viewer会告诉您DLL的确切位置。

这些通常是调试库加载问题的最简单方法，因为它们使问题非常明显：）

Answer 2

一种可能性是你有一台64位机器，编译了'Any Cpu'或64bit的c＃应用程序，c ++本机库或C ++ / CLI是32位。在这种情况下，系统会查找64位库。

确保所有应用程序都是针对相同的体系结构x86或x64构建的。

使用C ++ / CLR dll时C＃app崩溃
