You can get EventLogs using EventLog.GetEventLogs() method:
class Program
{
static void Main(string[] args)
{
EventLog log = EventLog.GetEventLogs().First(o => o.Log == "Security");
log.EnableRaisingEvents = true;
log.EntryWritten += (s, e) => { Console.WriteLine(e.Entry.EntryType); };
Console.WriteLine(log.LogDisplayName);
Console.ReadKey();
}
}
