C＃和C ++类继承混合 [英] C# and C++ class inheritance intermingling
问题描述
我有一个有趣的程序集，我想将它们放在一起：
I have an interesting stack of assemblies I want to put together:
-
通用程序集（C＃或C ++-CLI）
Common Assembly (C# or C++-CLI)
public class MyBase
{
public void MethodA()
{ ... }
private void MethodB()
{ ... }
protected virtual MethodC()
{ ... }
}
测试代码程序集（全部C ++-CLI）
Test Code Assemblies (all C++-CLI)
public class MySpecific : public MyBase{
protected: override MethodC();
};
测试模拟器（C＃）
Test Simulator (C#)
MySpecific obj = new MySpecific();
obj.MethodC();
而汇编1可能是C ++-CLI让事情变得更简单，我真的很想将汇编3保持在C＃中。这主要是一个练习，看是否可以在两个方向上都可以进行继承，但是我也有一个现实情况，该堆栈很有用。
While assembly 1 could be C++-CLI to keep things simpler, I'd really like to keep assembly 3 in C#. This is largely an exercise to see if inheritance could be done in either direction, but I also have a real-world case where this stack is useful.
我的第一个问题发现是C ++-CLI程序集无法编译，因为它无法将MyBase识别为类，即使我引用了程序集1以及看起来像是正确的命名空间也是如此。
The first problem I find is that the C++-CLI assembly does not compile because it doesn't recognize MyBase as a class, even though I have a reference to assembly 1 and what looks like the proper namespace.
如何编写可语言移植的类？
How do I write classes that are language-portable?
推荐答案
我认为您必须将MySpecific声明为托管类像这样的类：
I think you have to declare MySpecific as a managed class like this:
public ref class MySpecific : public MyBase { ... }
有关详细信息，请参见CLI / C ++文档。未经修改，您将无法使用旧的C ++代码，但我认为您应该牢记的所有内容。
See the CLI/C++ documentation for details. You will not be able to use old C++ code without modifications, but I think everything you have in mind should be possible.
