propagator.AutoUpdate.FileSource.Filename = fileUpdateSource;

// Preview TLEs (optional)
// Preview() returns a one dimension string of tles
Array tles = propagator.AutoUpdate.FileSource.Preview();
Regex rx = new Regex(@"^(?[-]?\d+) (?[-]?\d+[.]?\d+) (?[-]?\d+)$");
foreach (object line in tles)
{
    Match m = rx.Match(line.ToString());
    Console.WriteLine("SCC: {0}, orbit epoch: {1}, rev number: {2}", m.Groups["ssc"], m.Groups["orbitepoch"], m.Groups["revnumber"]);
}

// Propagate
propagator.Propagate();

Set SGP4 to auto-update from online source
