c# - C#播放列表实现

Question

我正在寻找一个简单的 C# 解决方案来管理播放列表。不是实际的播放功能，只是添加、删除、重新排序等等。

这样的代码存在吗？

Answer 1

假设您的播放列表中有这样的项目：

public class PlaylistItem { 
    public String Artist { get; set; }
    public String Album { get; set; }
    public String Song { get; set; }
    public TimeSpan Length { get; set; }
    public String SongFile { get; set; }
}

然后List<PlaylistItem>应该做：

var mySong = new PlayListItem { 
    Artist = "LMFAO", 
    Album = "Sorry for Party Rocking", 
    Song = "Sexy and I Know It", 
    Length = new TimeSpan(0,0,0,0,3,19,0), 
    SongFile = "C:\LMFAO.mp3" };
var myPlaylist = new List<PlaylistItem>();

// Add an item:
myPlayList.Add(mySong);

// Remove an item:
myPlayList.Remove(mySong);

// Reorder (assuming you've added some other items):
var song = myPlayList[0];
myPlayList[0] = myPlayList[1];
myPlayList[1] = song;

ETC...

如果您愿意，您甚至可以子类List<T>化以添加您自己的信息，例如当前正在播放的歌曲：

public class Playlist : List<PlaylistItem> {
    public Int32 CurrentSong { get; set; }
}
