如何在C#程序中使用C ++文件和类? [英] How do you use C++ files and classes in a C# program?

问题描述

我在这里遇到了麻烦，需要一些帮助.我有一个C ++文本经济型太空游戏，我曾经写过，现在我需要用图形和内容创建它的C#版本.但是我还不了解足够的C#来完全重写它.但是有人告诉我，有一种方法可以在C#程序中使用C ++文件和类，这将解决我的问题，直到我学到足够的知识才能完全用C#重写它们.但是这个朋友从未告诉过我该怎么做.这里有人可以帮我还是给我一些好的建议吗?我会很感激的，谢谢.

哦，顺便说一句，我使用的是Microsoft Visual Studio 2008，它是C ++和C#的.net版本.

I''m in a bit of a jam here and need some help. I''ve got a C++ text economic space game that I wrote a while back and I now need to create a C# version of it with graphics and stuff. But I do not know enough C# yet to completely rewrite it. But someone had told me that there is a way to use C++ files and classes in a C# program, and that that would solve my problem until I learned enough to completely rewrite them in C#. But this friend never told me how exactly to do that. Could someone here please help me or give me some good suggestions? I would sure appreciate it, thanks.

Oh, and by the way, I''m using Microsoft Visual Studio 2008 and it''s .net versions of C++ and C#.

推荐答案

实际上简单.
1.如果您的C ++代码是旧的非托管代码，请进行一些必要的修改，以使其与c ++.net代码兼容.
2.用它制作一个dll.
3.只需在新的c#.net项目中添加对该dll的引用.那里的所有代码都可以使用.

Actually it is very simple.
1. If your C++ code is old, unmanaged code, make a few necessary modifications in order for it to complile as c++.net code.
2. Make a dll out of it.
3. Simply add a reference to that dll in your new c#.net project. All of the code there will be accesible for use.

您需要为此使用DLLImport.

You need to use DLLImport for this.
