在C#中开发MP3播放器时，如何选择字典或数组来处理元数据？

How about a generic list?

通用列表怎么样?

// define song object.
public class Song 
{
    public string FileLocation { get; set; }
    public string FileName { get; set; }
    public string Artist { get; set; }
    public string Album { get; set; }
    public string TrackTitle { get; set; }
    public string AlbumArtwork { get; set; }
}

// create list of songs.
List sOngs= new List();

// add new song to list.
songs.Add(new Song {
        FileLocation = "/filepath/sade.mp3",
        FileName = "Sade", 
        Artist = "Sade", 
        Album = "Sade", 
        TrackTitle = "Smooth Operator", 
        AlbumArtwork "TBD"
});

// access first song in list.
Song sOng= songs[0];

// access property of song.
string trackTitle = song.TrackTitle;

Of course you could break this down into an even more object-oriented design by making the song properties complex objects as well. For example:

当然,通过使歌曲属性也成为复杂的对象,你可以将其分解为更加面向对象的设计。例如:

public class Album
{
    public string Name
    public DateTime ReleaseDate
    public string Artwork { get; set; }
}

public class Artist
{
    public string Name
    public List Albums
}

public class Song 
{
    public string FileLocation { get; set; }
    public string FileName { get; set; }
    public Artist Artist { get; set; }
    public string TrackTitle { get; set; }
}

And then, for example, access the album properties like this:

然后,例如,访问相册属性,如下所示:

string firstAlbumName = song.Artist.Albums[0].Name;

There doesn't seem to be anything there that would influence storage, do I would say "a list of classes", i.e. a List or similar, with

似乎没有什么会影响存储,我会说“类列表”,即List 或类似的,与

public class Track {
    public string Path {get;set;}
    ...
    public string Title {get;set;}
    public string ArtworkPath {get;set;}
}

If the volume is high, you might want to look at databases rather than in-memory storage. SQL Server (Express or Compact) for example, are both free. This may allow for more specialised indexing without much effort, plus pre-built persistence.

如果卷很高,您可能需要查看数据库而不是内存存储。例如,SQL Server(Express或Compact)都是免费的。这可以允许更加专业化的索引而不需要太多努力,以及预先构建的持久性。

The best way to store your data is in a database, there are different types a small free database to choose from. For example sqlite is nice. You can use sql for fast access of of the data (searching, grouping, etc).

存储数据的最佳方式是在数据库中,有不同类型的小型免费数据库可供选择。例如sqlite很好。您可以使用sql快速访问数据(搜索,分组等)。
