我使用 TagLib 从 .mp3 文件中检索信息并使用 LINQ to XML 将其显示到 XML 文档中，这是正确的代码：

static class Program
{   
    [STAThread]
    static void Main()
    {
        TagLib.File file = TagLib.File.Create(@"path of one of my .mp3 files");
        XDocument xdoc = new XDocument(
            new XDeclaration("1.0", "utf-8", "yes"),
            new XElement("Music", new XAttribute("id", 001),
                new XElement("Album", file.Tag.Album),
                new XElement("AlbumArtist", file.Tag.AlbumArtists),
                new XElement("Title", file.Tag.Title),
                new XElement("Track", file.Tag.Track),
                new XElement("Genre", file.Tag.Genres),
                new XElement("Path", Path.GetFullPath("El Gozo (version acústica).mp3")))
            );
        xdoc.Save(@"C:\Users\ivan_000\Music\Data.xml");   
    }
}

但是现在我一直在尝试多种方法来开发相同的程序，其中有几个 .mp3 文件存储在同一个 XML 文档中，但它不起作用。

static void Main()
{

    TagLib.File file = TagLib.File.Create(@"C:\Users\ivan_000\Music\El Gozo  (version acústica).mp3");
    TagLib.File file2 = TagLib.File.Create(@"C:\Users\ivan_000\Music\En el Trono está.mp3");
    TagLib.File file3 = TagLib.File.Create(@"C:\Users\ivan_000\Music\Por Siempre.mp3");

    XDocument xdoc = new XDocument(
        new XDeclaration("1.0", "utf-8", "yes"),
        new XElement("Music", new XAttribute("id", 001),
        new XElement("Album", file.Tag.Album),
        new XElement("AlbumArtist", file.Tag.FirstAlbumArtist),
        new XElement("Title", file.Tag.Title),
        new XElement("Track", file.Tag.Track),
        new XElement("Genre", file.Tag.FirstGenre),
        new XElement("Path", Path.GetFullPath("El Gozo (version acústica).mp3"))),
        new XElement("Music", new XAttribute("id", 002),
        new XElement("Album", file2.Tag.Album),
        new XElement("AlbumArtist", file2.Tag.FirstAlbumArtist),
        new XElement("Title", file2.Tag.Title),
        new XElement("Track", file2.Tag.Track),
        new XElement("Genre", file2.Tag.FirstGenre),
        new XElement("Path", Path.GetFullPath("Por Siempre.mp3"))),
        new XElement("Music", new XAttribute("id", 003),
        new XElement("Album", file3.Tag.Album),
        new XElement("AlbumArtist", file3.Tag.FirstAlbumArtist),
        new XElement("Title", file3.Tag.Title),
        new XElement("Track", file3.Tag.Track),
        new XElement("Genre", file3.Tag.FirstGenre),
        new XElement("Path", Path.GetFullPath("Por Siempre.mp3")))
    );
    xdoc.Save(@"C:\Users\ivan_000\Music\Data.xml");   
}

XML 文档可能只有一个根元素。您正在尝试创建三个。将元素放在单个根元素中。

var musicDir = Environment.GetFolderPath(Environment.SpecialFolder.MyMusic);
var paths = Directory.EnumerateFiles(musicDir, @"*.mp3");
var doc = new XDocument(
    new XElement("root", // place the Music elements under root
        from x in paths.Select((p, i) => new { Path = p, Index = i })
        let file = TagLib.File.Create(x.Path)
        select new XElement("Music",
            new XAttribute("id", x.Index + 1),
            new XElement("Album", file.Tag.Album),
            new XElement("AlbumArtist", file.Tag.FirstAlbumArtist),
            new XElement("Title", file.Tag.Title),
            new XElement("Track", file.Tag.Track),
            new XElement("Genre", file.Tag.FirstGenre),
            new XElement("Path", x.Path)
        )
    )
);
doc.Save(Path.Combine(musicDir, "Data.Xml"));
