使用 C++/CLR dll 时 C# 应用崩溃

本文关键字：应用 崩溃 dll C++ CLR 使用 | 更新日期: 2023-09-27 18:31:47

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

当项目为空时，一切都可以编译并运行良好，但是当我在本机C++应用程序中向我的类添加一些代码时，C# winforms应用程序中出现崩溃。

这是错误消息： 

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在正确的文件夹中。

这是来自视觉工作室的完整错误日志：

使用 C++/CLR dll 时 C# 应用崩溃

我建议看看Dependency Walker和Fusion Log Viewer。

依赖关系Walker会告诉你是否有任何DLL丢失你尝试加载的DLL。

Fusion Log Viewer 将告诉您尝试从何处加载 DLL。

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:)

一种可能性是你有一台 64 位机器，编译了 C# 应用程序为"任何 CPU"或 64 位，并且 c++ 本机库或 C++/CLI 是 32 位。在这种情况下，系统查找 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。
