Answer 1

Here is a sample to get the latest "Logon (4624)" and "Special Logon (4672)"

  var log = new EventLog
  {
    Source = "Microsoft Windows security auditing.",
    Log = "Security"
  };
  var latestLogon =
    log.Entries.Cast<EventLogEntry>()
      .Where(entry => entry.InstanceId == 4624 || entry.InstanceId == 4672)
      .OrderByDescending(i => i.TimeWritten)
      .FirstOrDefault();
