在C#中使用MFC C Dll [英] use of MFC C Dll in C#

问题描述

大家好

我有一个基于GUI的c代码.
我想将其转换为dll，然后使用此dll
在C#中.
我已经在c#中使用了c dll，但是该dll的代码不是基于GUI的.
通过将所有代码简单地编写到c中的类文件中并使用__declspec内部的函数，我可以创建DLL并在c#中使用

但是我的问题是如何在创建c的dll中创建基于gui的代码，然后使用
在C#中.



如何在c#plz帮助中使用MFC C dll

在此先感谢

Hi All

i have a code of c which is GUI based .
I want to convert it into the dll and then use this dll
in c#.
I already use c dll in c# but the code of that dll is not GUI based .
By simply writing that all code in a class file in c and using function inside __declspec I CREATE THE DLL and use in c#

But my problem is how to create gui based code in creating dll of c and then use
in c#.



How use MFC C dll in c# plz Help

Thanks in advance

推荐答案

原则上可以做到，但实际上没有任何实际意义.您最好编写纯.NET UI并使用C ++中的一些语义代码，也许根本不用MFC.

无论如何，如果要在.NET汇编中使用C ++代码，则只有两种方法.

第一种方法:使用P/Invoke.您可以学习它:
http://en.wikipedia.org/wiki/P/Invoke [ http://msdn.microsoft.com/en-us/library/Aa712982 [ ^ ].

此CodeProject文章也可能有用:基本P/调用 [

In principle, you can do it, but it makes no practical sense, really. You better write pure .NET UI and use some semantic code from C++, perhaps without MFC at all.

Anyway, you if want to use C++ code in .NET assembly, there are just two approaches.

First approach: use P/Invoke. You can learn it:
http://en.wikipedia.org/wiki/P/Invoke[^],
http://msdn.microsoft.com/en-us/library/Aa712982[^].

This CodeProject article can also be useful: Essential P/Invoke[^].

Second approach is based on using C++/CLI. You can either re-write your C++ code into C++/CLI or create a mixed-mode (managed+unmanaged) project combining C++/CLI with your legacy C++ code. You can then wrap your C++ code in C++/CLI ("ref") classes or structures and make them public. You can reference such mixed-mode assembly just like a normal .NET assembly in your C# project.
