從Java應用程序使用C API包裝器時出現異常

我想從C API使用C＃代碼。 C API實際上可以從Java應用程序中獲得。從Java應用程序使用C API包裝器時出現異常

我創建了一個C++/CLI包裝器來調用一個簡單的C＃函數，並驗證了它可以使用簡單的C++控制檯應用程序工作。我還編寫了C++ dll，可以與使用Java程序發佈的C API成功工作。儘管當我嘗試使用相同的程序調用C++/CLI包裝時，主機Java程序立即退出，但沒有任何錯誤。然後，我嘗試實例化C++/CLI對象並在try/catch塊中調用成員函數，但它仍然立即退出。這裏是我的代碼：

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(); 
}

當我附上在Visual Studio調試會話的Java應用程序（javaw.exe的），它的故障對「CutLoggerGraphWrapper目標文件」行。

我已經嘗試將我的dll放在幾個位置，包括與Java應用程序dll相同的文件夾，然後放在PATH環境變量中列出的文件夾中。我以爲它可能不會加載包裝或C＃DLL。這沒有改變任何東西。我無法理解Visual Studio輸出中可能出現的問題。這是來自輸出窗口的消息。有什麼建議麼？

我找到了我的問題的解決方案，它原來是C++/CLI包裝器和C＃dlls的位置。我必須在（appdirectory）/ jre/bin中找到dll。我在同一個目錄中看到一些微軟的dll後得出了這個結論。

「appdirectory」是正在使用的JRE的路徑。例如：'C：\ Program Files（x86）\ Java \ jdk1.7.0_45 \'。把DLL放在'\ jre \ bin \'中。 – Josh
