我正在尝试使用 C API 中的 C# 代码。C API 实际上可从 Java 应用程序中获得。

我创建了一个 C++/CLI 包装器来调用一个简单的 C# 函数，并使用一个简单的 C++ 控制台应用程序验证了它的工作原理。我还编写了 C++ dll，它可以与随 Java 程序发布的 C API 一起成功运行。尽管当我尝试使用同一个程序来调用 C++/CLI 包装器时，主机 Java 程序会立即退出而没有任何错误。然后我尝试实例化 C++/CLI 对象并在 try/catch 块中调用成员函数，但它仍然立即退出。这是我的代码：

try
{
CutLoggerGraphWrapper obj;
obj.SetRdoc(1.234);
}
catch (exception & e)
{
    AllocConsole();
    freopen("CONIN$", "r", stdin);
    freopen("CONOUT$", "w", stdout);
    freopen("CONOUT$", "w", stderr);
    cout << e.what() << endl;
    FreeConsole();
}

当我将 Visual Studio 中的调试会话附加到 Java 应用程序 (javaw.exe) 时，它会在“CutLoggerGraphWrapper obj”行出现故障。

我尝试将我的 dll 放置在多个位置，包括与 Java 应用程序 dll 位于同一文件夹中，然后放置在 PATH 环境变量中列出的文件夹中。我在想它可能没有加载包装器或 C# dll。这并没有改变什么。我无法从 Visual Studio 的输出中理解问题所在。这是来自输出窗口的消息。有什么建议么？

我找到了解决问题的方法，原来是 C++/CLI 包装器和 C# dll 的位置。我必须在 (appdirectory)/jre/bin 中找到 dll。在看到同一目录中的一些 microsoft dll 后，我得出了这个结论。
