c# - 无法读取简单的 xml 文件

Question

我知道这看起来像是一个愚蠢的简单问题，但我还是会问的。我一直在尝试阅读这个 xml 文件:

<Songs>
<song>
  <TrackID>1666</TrackID>
  <Name>What's the Matter Here?</Name>
  <Artist>10,000 Maniacs</Artist>
  <AlbumArtist>10,000 Maniacs</AlbumArtist>
  <Composer>Natalie Merchant/Robert Buck</Composer>

我正在使用这段代码来阅读上面的内容:

    private static void LoadSongsFromITunes(string xmlFile)
    {
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.IgnoreComments = true;
        settings.IgnoreWhitespace = true;
        string album=null ;
        string artists=null ;
        string genres=null ;
        string  year=null ;
        string duration=null ;

        try
        {
            using (XmlReader reader = XmlReader.Create(xmlFile, settings))
            {
                string xmlContent;

                while (reader.Read())
                {
                    if (reader.NodeType != XmlNodeType.Element) continue;
                    xmlContent = "";
                    string name=null;
                    if (reader.Name == "Name")
                    {
                        name = reader.ReadString().ToString();
                    }
                    if (reader.Name == "Artist")
                    {
                        artists = reader.ReadString().ToString();
                    }
                    if (reader.Name == "Album")
                    {
                        album = reader.ReadString().ToString();
                    }
                    if (reader.Name == "Genre")
                    {
                        genres = reader.ReadString().ToString();
                    }
                    if (reader.Name == "Year")
                    {
                        year = reader.ReadString();
                    }
                    if (reader.Name == "Duration")
                    {
                        duration  = reader.ReadString().ToString();
                    }
                    Console.WriteLine(name);
                }
            }
        }
        catch
        {

        }

但是，读取器似乎只返回 null。我已经通过调试器跨过了代码，但我不太明白这段代码有什么问题。P.S:有人可以提供更好的方法吗？比如使用 xml 链接之类的？

LINQ 到 XML:

var doc = XDocument.Parse(xml);

var result = doc
    .Root.Elements("song")
    .Select(e => 
        new { Name = (string)e.Element("Name"), Artist = (string)e.Element("Artist") });

foreach (var val in result)
{
    Console.WriteLine(val);
}
