我正在尝试将 XML 文件反序列化为几个类对象:艺术家、专辑和歌曲

这是当前的设置:

static void Main(string[] args)
{
    var riseAgainst = DeSerializer(CreateElement());
    Console.WriteLine(string.Format("Band: {0}",riseAgainst.Name));
    Console.WriteLine("-----------------------------");
    Console.WriteLine(string.Format("Album: {0}",riseAgainst.Album.Name));
    Console.WriteLine("-----------------------------");
    Console.WriteLine("Song List:\r");
    
    foreach(var s in riseAgainst.Album.Songs)
    {
        Console.WriteLine(string.Format("Song: {0}", s));
    }
    Console.ReadLine();
}

static XElement CreateElement()
{
    return new XElement("Artist",
                new XElement("Name", "Rise Against"),
                new XElement("Album",
                    new XElement("Name", "Appeal to Reason"),
                    new XElement("Songs",
                        new XElement("Song", "Hero of War"),
                        new XElement("Song", "Savior"))
                )
            );
}

static Artist DeSerializer(XElement element)
{
    var serializer = new XmlSerializer(typeof(Artist));
    return (Artist)serializer.Deserialize(element.CreateReader());
}


public class Artist
{
    public string Name { get; set; }
    public Albums Album { get; set; }
}

public class Albums
{
    public string Name { get; set; }
    public Songs Songs { get; set; }
}

public class Songs
{
    public string Song { get; set; }
}

我目前遇到的问题是，如果有多个艺术家、专辑和/或歌曲，那么它只会填充第一个。我怎样才能让它填满专辑的所有内容，或者艺术家的所有歌曲......等等我尝试将它们设置为数组但它没有用。提前致谢。

最佳答案

我稍微修改了你的类(class)，现在艺术家有一个 List<Album>和相册有 List<Songs>

我不得不稍微修改生成的 xml 以确保它正确填充类。这是代码

static void Main(string[] args)
{
    var riseAgainst = DeSerializer(CreateElement());
        Console.WriteLine(string.Format("Band: {0}",riseAgainst.Name));
        Console.WriteLine("-----------------------------");
        Console.WriteLine(string.Format("Album: {0}",riseAgainst.Albums.First().Name));
        Console.WriteLine("-----------------------------");
        Console.WriteLine("Song List:\r");
        foreach(var s in riseAgainst.Albums.First().Songs)
        {
            Console.WriteLine(string.Format("Song: {0}", s.Name));
        }
        Console.ReadLine();



    static XElement CreateElement()
    {
        return new XElement("Artist",
                new XElement("Name", "Rise Against"),
                new XElement("Albums",
                    new XElement("Album",
                        new XElement("Name", "Appeal to Reason"),
                        new XElement("Songs",
                            new XElement("Song", new XElement("Name", "Hero of War")),
                            new XElement("Song", new XElement("Name", "Savior")))
                        ))
            );
    }

    static Artist DeSerializer(XElement element)
    {
        var serializer = new XmlSerializer(typeof(Artist));
        return (Artist)serializer.Deserialize(element.CreateReader());
    }
}

public class Artist
{
    public string Name { get; set; }
    public List<Album> Albums { get; set; }
}

public class Album
{
    public string Name { get; set; }
    public List<Song> Songs { get; set; }
}

public class Song
{
    public string Name { get; set; }
}

希望对您有所帮助。这不包括您想要不止一位艺术家的情况。
