如何从C ++ COM迁移到C ++ CLI [英] How to migrate from C++ COM to C++CLI

问题描述

我有一个C ++ DLL通过COM暴露的东西。我想将其转换为暴露受管接口的C ++ / CLI。理想情况下，我只需添加CLI和逐个转换接口。到目前为止，我没有任何成功，所以我正在寻找一个具体的策略。

I have a C++ DLL that exposes stuff via COM. I want to convert it to C++/CLI that exposes a managed interface. Ideally I just add CLI and convert interfaces one by one. So far I haven't succeeded in anything, so I'm looking for a specific strategy.

更多细节：
很久以前，我创建了一个应用程序使用COM在C＃和C ++之间来回通信。我对COM感到不舒服，并且在C ++端需要注册和跳跃。

More detail: A long time ago, I created an app using COM to communicate back and forth between C# and C++. I'm sick of COM, and the registration and the hoop jumping needed on the C++ side.

我想使用C ++ / CLI，让整个事情工作托管代码与从C ++ / CLI到我正在使用的本机库的偶尔调用。

I want to use C++/CLI, and get the whole thing working as managed code with the occasional call from C++/CLI to native libraries I'm using.

任何人都可以建议一个温和的迁移路径，这样我可以有CLI和COM在我去的时候，通过类测试将事物转换成类？或者类似的东西。

Can anyone suggest a gentle migration path, such that I can have both CLI and COM going, and convert things over class by class testing as I go? Or something like that.

要清楚：我目前有本地C ++代码定义和实现COM接口。我有C＃代码使用COM属性导出类。所有这些东西都注册COM互操作，并有两个方向的呼叫。我希望将C ++切换到CLI，并切换到C ++中的托管类，而不是COM类。

To be clear: I currently have native C++ code defining and implementing COM interfaces. I have C# code using COM attributes to export classes. All this stuff gets registered for COM interop, and there are calls in both directions. I hope to switch the C++ to CLI and switch to managed classes in C++ rather than COM classes.

问题更新为Ramhound：无论如何，我跑进砖墙。打开/ clr在C + + DLL给我来自其他尝试连接到该C ++代码的东西的链接错误。 （不可读的ATL / COM消息，驱使我远离C ++）

Question updated for Ramhound: Anyway, I'm running into brick walls. Turning on /clr on a C++ dll gives me link errors from other stuff trying to connect to that C++ code. (Unreadable ATL/COM messages of the sort that drive me away from C++)
