EventLogEntry Class
Assembly: System (in system.dll)
You usually will not create instances of EventLogEntry directly when working with the EventLog class. The Entries member of the EventLog class contains a collection of EventLogEntry instances, which you iterate over when reading by using the EventLogEntryCollection.Item class index member.
Windows 98, Windows Millennium Edition Platform Note: Event logs are not supported on Windows 98/Windows Millennium.
