在 .NET 应用程序中添加对旧 DLL 的引用

Question

我正在尝试向我的 .NET 项目中添加对来自 Army.mil 的文件 corscon_v6.dll 的引用。

添加文件时提示：'corpscon_v6.dll 无法添加。请确保该文件是可访问的，并且它是一个有效的程序集或 COM 组件。接下来，我运行 Dependency Walker，发现 DLL 内部有两个问题：找不到 IESHIMS.DLL 和 WER.DLL。我已经搜索了这些 DLL，似乎不需要它们。我也害怕从其他站点下载任何类型的 DLL，因为我无法信任它们，而且许多站点都说不要这样做。

接下来，我运行 tlbimp.exe 来转换 DLL，但这也不起作用。这会返回一个错误：输入文件 'c:\temp\corpscon_v6.dll' 不是有效的类型库。我也尝试过对其进行 regsvr32 操作，但这会返回“未找到入口点错误”。考虑到我花在处理完全损坏的陆军兵团网站上的时间，我完全不知道如何让他们宏伟的 CORPSCON DLL 在我的项目中工作/

希望这会有所帮助。在检索答案之前，这一切都对我有用。 或许你能弄清楚这位老人对 C 的东西有什么不知道的地方。 祝你好运

导入 System.Runtime.InteropServices
