visual-studio - c#怎么调用c++的类和函数

Answer 1

一种方式是托管 c++，但是有可能对代码更改较大，
另一种是链接

Answer 2

check out C++/CLI (aka managed C++). Write a wrapper that uses your native class as a member

最好给每一个用到的native concrete class 写一个对应的Interface，在Managed C++ 里用 INativeCore 而不是NativeCore ，来避免一些坑

// in your native core:

// define an interface wrapper for your native core
class INativeCore{
// ...
}
class NativeCore: public INativeCore{
// ... 
}

// in your C++/CLI code
ref public class ManagedClass{
private:
  INativeCore* pCore; // delegate all method calls to native core
public:
  void foo(){
  pCore->foo(); 
}
// ... other methods
}
