C# 需要读取XDocument中的重复值

我需要解析XDocument中的以下XML：

<RESPONSES>

我可以根据标签来判断曲目的数量，但除此之外，曲目的数量会因专辑而异。下面是我解析XDocument的现有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();



        }

下面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; }
    }
}

但我不知道如何解析这些轨迹，因为无法提前知道给定响应中会有多少轨迹。有人能帮我解决这个问题吗

哦，当我在做这件事的时候，我如何转换符号和APO；替换为除string.replace以外的撇号

提前谢谢

只需添加

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()

到您的代码

因此，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();

谢谢LB-这很好用！剩下的一个问题是：如何在曲目中填充AlbumId，这是返回Album->AlbumId的外键？哦，当我在做这件事的时候，我如何转换符号和APO；替换为字符串以外的撇号。@user3171260 a如果您已经执行了stringitem.ElementGN_ID，只需在轨迹块中重复它。b代表&apos；你不必做任何特别的事。xml解析器可以处理它。
