I need a regex that scans the page for magnet links and gets the magnet links in matches collection...

What I have tried:

private void downloadPage(string pageLink)
        {
            string s = (new System.Net.WebClient()).DownloadString(pageLink);

            while (!string.IsNullOrWhiteSpace(s))
            {
                if (s.StartsWith(@"magnet:?xt=urn:btih:"))
                {
                    for (int d = 20; d < s.Length; d++)
                    {
                        if (s[d] == '"')
                        {
                            System.Diagnostics.Process.Start(s.Substring(0, d));
                            s = s.Substring(d);
                            break;
                        }
                    }
                }
                else
                {
                    s = s.Substring(1);
                }
            }
        }

This link extracts URLs from a page. It should not be that difficult to modify it to do what you want: Extracting all links from a HTML page[^]
