create key-value pair Borland C++

Question

I'm trying create some Dictionary in Borland 2010 C++.

TDictionary__2<AnsiString, AnsiString> *d = new TDictionary__2<AnsiString, AnsiString>();

I got error: [BCC32 Error] Generics.collections.hpp(542): E2347 Parameter mismatch in read access specifier of property Items

what I do wrong?

C++Builder can only consume instances of Delphi-based Generics types, like TDictionary, that originate from Delphi code. Unfortunately, it cannot instantiate Delphi-based Generics types. If you are not trying to interact with Delphi code, then you should use the STL's std::map class instead:

#include <map>

std::map<AnsiString, AnsiString> d;
