You should be able to use the link below to shuffle your playlist.

Answer 2

Create a custom class:

public class FileItem
{
    public string FilePath { get; set; }
    public string ShortName { get; set; }
}

And then create a new instance of this class when you get a file from the OpenFileDialog, save the openFileDialog1.FileName to FilePath property, and then get the short file name using the Windows.IO.Path.GetFileName() method.

Rather than adding the file path to the ListBox directly from the OpenFileDialog, add this instance of your class.

And change the DisplayMember property of your ListBox to "ShortName", this way the "short name" of your file path will be displayed in the ListBox.
