Rainmeter NowPlaying in C＃

是否有可能在Rainmeter中使用C＃项目中的NowPlaying.dll（C++），如果是这样的话？如果没有Rainmeter正在运行，可以使用.dll吗？我想从Windows Media Player中获取当前歌曲的元数据。Rainmeter NowPlaying in C＃

这是headerfiles（PlayerWMP.h）之一：

#define __PLAYERWMP_H__ 

#include "Player.h" 
#include <wmp.h> 
#include <wrl/client.h> 

class PlayerWMP : public Player 
{ 
public: 
virtual ~PlayerWMP(); 

static Player* Create(); 

virtual void UpdateData(); 

virtual void Pause(); 
virtual void Play(); 
virtual void Stop(); 
virtual void Next(); 
virtual void Previous(); 
virtual void SetPosition(int position); 
virtual void SetRating(int rating); 
virtual void SetVolume(int volume); 
virtual void OpenPlayer(std::wstring& path); 
virtual void ClosePlayer();
