推荐答案

据我所知，这个lib是DirectShow的包装，因此可以在托管环境中使用. DirectShow主要包含有关播放的内容.要实现下一首和上一首，您需要具有某种f播放列表(可能将歌曲存储在arraylist中)，并且当用户按下下一首/上一首歌曲时，您只需从列表中获取下一首歌曲，然后使用quartzlib播放即可.

As far as i know this lib is a wrapper on directshow so that it can be used from managed world. The directshow has mainly stuff dealing with playback. to achieve next and previous you need to have some kind f playlist(perhaps store songs in arraylist) and when user presses the next/prev then you just fetch the next song from list and play using quartzlib.

可以使用简单的类来创建播放列表，该类可以具有函数下一个或上一个文件的returninf文件路径.然后可以将此路径推送到crystallib进行播放

The playlist can be created using simple class which can have functions returninf filepath of next or previous file. This path can then be pushed to quartzlib for playback

MusicDrawer-A-Simple-Music-player-using-WMP-SDK[^]

This is a music player I wrote some time back. This is using WMPSDK for playback but the playlist is created inside this application only.

So you can replace the MWMPEngine.cs class with your class that will use directshow using quartzlib and the playlist and other classes can be used/referred from here.

I have an exact same player written using managed directX around 2.5 years back. which is more preferred way of doing things from C# than using quartzlib. I suggest you have a look at Managed direct-X too unless your requirement is specifically stating the use of quartzlib. I will check my home computer''s hard-drive to see if I could find the directX version of this player.
