__declspec(delphiclass) 을 지정해주는 것만으로는 실행파일에 클래스에 대한 개별적인
RTTI 정보가 생성이 되기는 하지만, RTTI 구현 레이어에서 참조되는 RTTI 테이블 구조 자체를
생성해 주는 것은 아니더군요.

아래 처럼 ... 따로 RTTI 속성을 지정해 주면 됩니다.

<소스코드>

#pragma explicit_rtti methods(public, protected)

class __declspec( delphiclass  ) CCC : public TObject
{
public:
    virtual CCC(){};
    __classmethod String __fastcall MyClassName();
};

System::String __fastcall CCC::MyClassName()
{
    return UTF8ToString(*PShortString(*PPointer(System::PByte(this) + vmtClassName)));
}

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    TRttiContext context;
    TRttiType *type = context.GetType(__classid(CCC));
    DynamicArray<TRttiMethod*>theMethods = type->GetMethods();

    for( int i = 0; i < theMethods.Length; i++ ) {
        TRttiMethod *method = theMethods[i];
        OutputDebugStringW(method->Name.c_str());
    }
}

다음은 의도한대로 제대로 출력되고 있는 Debug 덤프 입니다.
