Hi Richard,
can you please tell me how to pass query in above method for time span. i am writing like below but it is saying invalid query.

if (EventLog.Exists(LogName))
{
EventLogSession logsession = new EventLogSession();
logsession.ExportLogAndMessages(LogName, PathType.LogName, "*[TimeCreated[@SystemTime>='2017-11-28T02:49:35.000Z' and @SystemTime<='2017-11-28T03:50:51.999Z']]", subfolderpath, false, CultureInfo.CurrentCulture);

}
