How to retrieve event log other than Application category?

Question

I'm trying to retrieve some event log in a category that is different from Application. For example, I want to get the info in "Microsoft-Windows-Application Server-Applications/Operational". Below it is my code

EventLog log = new EventLog("Microsoft-Windows-Application Server-Applications/Operational");
int index = log.Entries.Count - 1;
Debug.WriteLine(log.Entries[index].Message);

But it always shows the error:

The event log 'Microsoft-Windows-Application Server-Applications/Operational' on computer '.' does not exist.

If I simply use "Application", then I can get the log in Application category.

How to get log for "Microsoft-Windows-Application Server-Applications/Operational"?

Thanks

The EventLog class only lets you access Windows event logs. You will want to use instead the EventLogReader found in System.Diagnostics.Eventing.Reader namespace.

        EventLogQuery query = new EventLogQuery("Microsoft-Windows-Application Server-Applications/Operational", PathType.LogName, "*");
        EventLogReader reader = new EventLogReader(query);
        EventRecord eventRecord;
        while ((eventRecord = reader.ReadEvent()) != null)
        {
            Console.WriteLine(String.Format("{0} - {1}",
                eventRecord.TimeCreated,
                eventRecord.FormatDescription()));
        }
