Blending C # and C ++ Class Inheritance

Question

I have an interesting assembly stack that I want to build:

• General assembly (C # or C ++ - CLI)

  public class MyBase
  {
  public void MethodA()
  { ... }
  private void MethodB()
  { ... }
  protected virtual MethodC()
  { ... }
  }
  

• Test code subscribers (all C ++ - CLI)

  public class MySpecific : public MyBase{
  protected: override MethodC();
  };
  

• Test Simulator (C #)

  MySpecific obj = new MySpecific();
  obj.MethodC();
  

While assembly 1 can be C ++ - CLI, to simplify the task, I would really like to save assembly 3 in C #. This is basically an exercise to make sure inheritance can be done in any direction, but I also have a real case where this stack is useful.

The first problem that I find is that the C ++ - CLI assembly does not compile because it does not recognize MyBase as a class, although I have a reference to assembly 1 and what looks like its own namespace.

How to write classes that carry the language?

Answer 1

, MySpecific :

public ref class MySpecific : public MyBase { ... }

. CLI/++. ++ , , , , .

Answer 2

:

`#using "..\common\bin\debug\common.dll"`

, /clr- ( ++ ), , .

Answer 3

This will work fine, but you need to use the C ++ / CLI syntax if you work with managed types (i.e.: inherit from a C # class). So, in this case, the element in 2. should look bigger:

public ref class MySpecific : public MyBase { ... }

Make sure the file is compiled with / clr. Good.
