如何在Winrt应用程序中使用路径访问文件媒体播放列表和库功能 [英] How Do I Access Files Using Path In Winrt App For Media Playlist And Library Features

问题描述

见鬼！我是winrt的新手，我正计划开发一个winrt应用程序，用于播放音频/视频，创建播放列表和媒体库的简单媒体播放器。



As我想我会制作一个播放列表并在保存播放列表时序列化它。此播放列表类将保留可能位于硬盘中任何位置的音频/视频文件的路径。类似地，对于库，我将在数据库中存储文件信息和路径以供将来在数据库中访问。但事实证明我只能使用拣货员访问系统上的其他文件（少数文件除外）。



但我们知道有库和播放列表功能在win8中的winrt音乐应用程序，必须有一个合法有效的方法。



如果你能帮我解决这个问题，我将非常感谢你因为这对我来说非常重要



提前谢谢

Hell there! I am new to winrt and i was planning on developing a winrt app for a simple media player that would play audio/video, create playlist and have media library.

As i was thinking i would make a playlost class and serialize it when a playlist is saved. This playlist class would be holding path to the audio/video files that could be anywhere in the hard disk. Similarly for library i would store files info and path in the database for future access in the database. But as it turned out i can only access other files on system using pickers (except for few files).

But as we know that there is library and playlist features in the winrt music app in win8, there must be a legal and efficient way to do so.

I would be thankfull to you if u could help me out on this one because this is really important for me

Thanks in advance
