        trackList.Add(new Track { TrackID = 5678,Name = "I'm Gonna Be (1000 Miles)",Artist = "The Proclaimers(II)",Album = "Finest(II)", PlayCount = 20,SkipCount = 2});
        trackList.Add(new Track { TrackID = 9101,Name = "I'm Gonna Be (2000 Miles)",Artist = "The Proclaimers(III)",Album = "Finest(II)", PlayCount = 40,SkipCount = 3});

        //How to sort based on column name:Album 
        //something like this below.
        trackList.Sort(trackList([0 4]);
        //How to remove rows after search items in a column based on some criteria
        trackList.RemoveAll(Album => Album.Contains("(II)"));
         //How to Populate resuts in a listbox
         //listBox1.DataSource = trackList();
    }
    public class Track
    {
        public int TrackID { get; set; }
        public string Name { get; set; }
        public string Artist { get; set; }
        public string Album { get; set; }
        public int PlayCount { get; set; }
        public int SkipCount { get; set; }
    }

  1. 如何根据列名称进行排序：相册

  2. 查找列中的项目并删除这些行。

  3. 结果应放在列表框中，也可以创建新列表。

排序和删除 C# 多维列表中的行

您可以使用 LINQ：

trackList = trackList
    .Where(t => !t.Album.Contains("(II)"))
    .OrderBy(t => t.Album)
    .ToList();

顺便说一句，这不是一个多维列表，而是一个List<Track>.
