尽管链接到具有导出符号的.lib文件，仍然从管理链接到非托管C ++的链接错误

尽管有关于使用和链接到C ++ / CLI包装器dll中的非托管C ++代码的各种帖子，我无法解决这些链接问题。

Despite following various posts on using and linking to unmanaged C++ code from a C++/CLI wrapper dll, I cannot resolve these link issues.

我有一个非托管的本地C ++ dll与一个简单的类，导出/导入符号

I have a unmanaged native C++ dll with a simple class, exporting/importing symbols accordingly

// MyClass.h
#ifdef _EXPORTING
   #define DLL_PUBLIC __declspec(dllexport)
#else
   #define DLL_PUBLIC __declspec(dllimport)
#endif

class DLL_PUBLIC MyClass { . . . };

我可以看到.dll和.lib链接器文件生成后生成。

And I can see .dll and .lib linker file being generated after building.

然后我有一个托管的C ++ / CLI包装项目（也是一个dll），链接到Linker-> Input-> Additional Dependencies设置中的MyClass.lib。在包装器项目中还包括MyClass的.h文件，我可以看到sln可以看到MyClass.h文件。

Then I have the managed C++/CLI wrapper project (also a dll), which links to the MyClass.lib in the Linker->Input->Additional Dependencies setting. Also included the .h file from MyClass in the wrapper project, and I can see the sln can see MyClass.h file.

// MyClassAdaptor.h

#include "MyClass.h"

namespace WrapperLayer
{
    public ref class MyClassAdaptor 
    { 
      . . . 
    private:
        MyClass* _myclass;  
    }; 
}

可能缺少什么？
