问题描述

我有一套用C ++编写的类源，我想使用C＃中的那些，可以

我只是把它们变成了一个常规DLL并导出这些和DllImport这些来自C＃的
没有问题？


这很容易吗？

解决方案

您不能将DllImport用于类，只能使用普通的C风格函数。

因此，你应该实现一种Facade API作为托管代码和非托管面向对象的C ++代码之间的桥梁。


你也可以公开你的通过COM的C ++类 - 这将在一定程度上保留非托管库的

面向对象，但是

也需要更多的努力。

程序集并使其对C＃可见吗？

Hi,

I have a set of classes source in C++ and I want to use those from C#, can
I just make these into a regular DLL and export these and DllImport these
from C# with no problems?

Is it that easy?

解决方案

Hi,

You cannot use DllImport with classes, only with plain C-style functions.
Therefore, you should probably implement a kind of facade API serving as a
bridge between the managed code and the unmanaged object-oriented C++ code.

You can also expose your C++ classes through COM - this would retain the
object-orientness of your unmanaged library to a certain degree, but would
also require more effort.

Cant I make a mixed mode assembly?

I mean I have the class source here (Its not mine) and can I make a new .NET
assembly in C++ and make it visible to C# that way?

I just need the fastest way to get access to these classses in C#
I really dont care for the complexity or s.hitness of the library I have to
use. I just have a few days to get it visible in C# :D
