Remove one event from eventlog (or cast EventRecord to EventLogEntry)

Question

My code sifts through events from a remote PC to test whether there are some 6008 (unexpected reboot) events.

I'm using code like:

EventLog log = new EventLog("System",remoteMachine);
EventLogEntryCollection entries = log.Entries;
var entries_filtered = entries.Cast<EventLogEntry>().Where (x => x.EventID=6008);
foreach (EventLogEntry entry in entries) {//my logic here}

During the process, I don't like the way that every event is logged ('reading event'), and so I've come up with two solutions:

1. Find a way to delete events with some features, so I can delete my reading events

2. Before reading, copy the evtx file and read event from this file.

But in this case, I need to use something like:

EventLogReader elr = new EventLogReader("C:\\myevents.evtx");    
EventRecord a = elr.ReadEvent();

I need to find a way to cast the EventRecord to a EventLogEntry or the EventReader to a EventLogEntryCollection to remove the need to change the entire logic beneath.

Any ideas for the two cases?

Thanks
