我在XDocument中有以下XML需要解析：

我可以根据标签判断曲目的数量，但除了曲目数量因专辑而异。这是我现有的用于解析XDocument的C＃代码：

   var albums = new List<Album>();
        try
        {
            albums = (from item in inputDoc.Descendants("ALBUM") //.Elements("GN_ID")

                      select new Album
                          {
                              AlbumId = (string)item.Element("GN_ID"),
                              ArtistName = (string)item.Element("ARTIST"),
                              AlbumName = (string)item.Element("TITLE"),
                              TrackCount = (int)item.Element("TRACK_COUNT"),
                              Year = (string)item.Element("DATE"),
                              Genre = (string)item.Element("GENRE"),
                              CoverArt = item.Elements("URL").First(u => u.Attribute("TYPE").Value == "COVERART").Value.ToString(),
                              Biography = item.Elements("URL").First(u => u.Attribute("TYPE").Value == "ARTIST_BIOGRAPHY").Value.ToString()

                          }).ToList();



        }

这是我正在阅读的结构：

namespace MusicApp.Model
{
    public class Album
    {
        public string ArtistName { get; set; }
        public string AlbumId { get; set; }
        public string AlbumName { get; set; }
        public int TrackCount { get; set; }
        public string Year { get; set; }
        public string Genre { get; set; }
        public string CoverArt { get; set; }
        public string Biography { get; set; }

        // Navigation properties
        public ICollection<Track> Tracks { get; set; }
    }
    public class Track
    {
        public string TrackId { get; set; }
        public int TrackNumber { get; set; }
        public string TrackName { get; set; }
        public string AlbumId { get; set; }
    }
}

但是我不知道如何解析曲目（假设没有事先知道在给定的回复中会有多少。有人可以帮我解决这个问题吗？

哦 - 当我在它的时候，我该如何转换“Ampersand-'s”？到一个撇号（除了string.replace（））。

提前致谢！

Answer 1

添加

Tracks = item.Elements("TRACK")
            .Select(t=> new Track{
                TrackNumber = (int)t.Element("TRACK_NUM"),
                TrackName = (string)t.Element("TITLE"),
                TrackId = (string)t.Element("GN_ID"),
            }).ToList()

代码......

所以整个代码将是

var albums = (from item in inputDoc.Descendants("ALBUM") 

            select new Album
            {
                AlbumId = (string)item.Element("GN_ID"),
                ArtistName = (string)item.Element("ARTIST"),
                AlbumName = (string)item.Element("TITLE"),
                TrackCount = (int)item.Element("TRACK_COUNT"),
                Year = (string)item.Element("DATE"),
                Genre = (string)item.Element("GENRE"),
                CoverArt = item.Elements("URL").First(u => u.Attribute("TYPE").Value == "COVERART").Value.ToString(),
                Biography = item.Elements("URL").First(u => u.Attribute("TYPE").Value == "ARTIST_BIOGRAPHY").Value.ToString(),
                Tracks = item.Elements("TRACK")
                        .Select(t=> new Track{
                            TrackNumber = (int)t.Element("TRACK_NUM"),
                            TrackName = (string)t.Element("TITLE"),
                            TrackId = (string)t.Element("GN_ID"),
                        }).ToList()
            }).ToList();

需要读取XDocument中的重复值
