예제

다음 코드 예제에서는 EventLogEntry 클래스의 사용을 보여 줍니다. 이 예제에서 문은 switch 콘솔 입력을 사용하여 지정된 이벤트 유형에 대한 이벤트 로그 항목을 검색합니다. 일치하는 항목이 발견되면 로그 항목 원본 정보가 콘솔에 표시됩니다.

설명

일반적으로 클래스를 사용할 때 직접 인스턴스를 EventLogEntryEventLog 만들지 않습니다. 클래스의 멤버에는 Entries 클래스 인덱스 멤버를 사용하여 읽을 때 반복하는 인스턴스 컬렉션 EventLogEntry 이 EventLogEntryCollection.Item[] 포함 EventLog 됩니다.
