How to download .ts files in m3u8

Question

I want to download .ts links in m3u8 before they expire. I am able to open m3u8 file with vlc player but using mediatoolkit it does not download .ts links to download. I will merge the ts files into one video later. Please help I only know c#

public class M3U8Processor
{
    public static void DownloadSegmentsFromM3U8(string m3u8Content)
    {
        List<string> segmentUrls = ParseM3U8(m3u8Content);
        string savePath = Path.Combine(Directory.GetCurrentDirectory(), "records");
        DownloadSegments(segmentUrls, savePath);
    }

    private static List<string> ParseM3U8(string m3u8Content)
    {
        List<string> segmentUrls = new List<string>();
        string[] lines = m3u8Content.Split('\n'); // Split \n

        foreach (string line in lines)
        {
            if (!line.StartsWith("#EXT"))
            {
                segmentUrls.Add(line.Trim()); // Trim 
            }
        }

        return segmentUrls;
    }

    private static void DownloadSegments(List<string> segmentUrls, string savePath)
    {
        using (var engine = new Engine())
        {
            for (int i = 0; i < segmentUrls.Count; i++)
            {
                string segmentUrl = segmentUrls[i];
                bool isValidUrl = UrlValidator.IsUrlValid(segmentUrl);
                Console.WriteLine("isValidUrl: " + isValidUrl);
                string fileName = $"{i + 1}.ts";

                try
                {
                    var inputFile = new MediaFile { Filename = segmentUrl };
                    var outputFile = new MediaFile { Filename = Path.Combine(savePath, fileName) };
                    var options = new ConversionOptions { Seek = TimeSpan.FromSeconds(0) };
                    engine.Convert(inputFile, outputFile, options);

                    Console.WriteLine($"Segment {i + 1} downloaded and saved successfully.");
                }
                catch (Exception ex)
                {
                    Console.WriteLine($"Error downloading segment {i + 1}: {ex.Message}");
                }
            }
        }
    }
