在C＃.NET中运行C ++代码 [英] Run C++ code in C#.NET

问题描述

一位商业伙伴告诉我，我应该能够在
C＃.NET环境中运行C ++代码，因为C ++和C＃属于同一个系列。


他发给我下面的代码并要求我在C＃.NET环境中运行。我b $ b得到了很多编译错误，因为#include的东西不存在于

C＃中！谁能告诉我下面的代码是否应该在C＃.NET中运行？

A business associate told me that I should be able to run C++ code in
C#.NET environment because C++ and C# belong to the same family.

Your business associate was wrong.

Now, there is a version of C++ for the .NET framework, called C++/CLI, but
there are typical certain changes that need to be made to adapt a generic
C++ program to it.

这篇关于在C＃.NET中运行C ++代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
