将 XElement 反序列化为类

Question

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; }
}

我当前遇到的问题是，如果有多个艺术家、专辑和/或歌曲，那么它只会填充第一个。我怎样才能做到这一点，以便它填充专辑中的所有内容，或艺术家的所有歌曲......等等我尝试将它们设置为数组，但它不起作用。提前致谢。

Answer 1

我对你的类进行了一些修改，所以现在 Artist 有一个 List 并且 Album 有 List

我必须稍微修改生成的 xml 以确保它正确地填充了类。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; }
}

希望有帮助。这不包括您想要多个艺术家的情况。
