Question

 private void button1_Click(object sender, EventArgs e)
    {
        var trackList = new List<Track>();
        trackList.Add(new Track{ TrackID = 1234, Name = "I'm Gonna Be (500 Miles)", Artist = "The Proclaimers(I)", Album = "Finest(I)", PlayCount = 10, SkipCount = 1 });
        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});
        trackList.Add(new Track { TrackID = 1213,Name = "I'm Gonna Be (4000 Miles)",Artist = "The Proclaimers(IV)",Album = "Finest(IV)", PlayCount = 80,SkipCount = 4});

        //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; }
    }

如何根据列名进行排序：相册
在列中查找项目并删除这些行。
结果应放在列表框中，或者可以创建新列表。

Answer 1

您可以使用LINQ：

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

顺便说一下，它不是多维列表，而是List<Track>。
