설명

EventLogEntryCollection 인스턴스와 연결된 항목을 읽을 때 클래스를 EventLog 사용합니다. Entries 클래스의 EventLog 속성은 이벤트 로그에 있는 모든 항목의 컬렉션입니다.

새 항목이 기존 목록에 추가되므로 컬렉션을 단계별로 실행하면 원래 을 만든 후에 만든 항목에 EventLogEntryCollection액세스할 수 있습니다. 그러나 전체 목록을 확인한 후에는 새 항목으로 업데이트되지 않습니다.

속성

Count	이벤트 로그의 엔트리 수, 즉 EventLogEntry 컬렉션의 요소 수를 가져옵니다.
Item[Int32]	0부터 시작하는 인덱스를 기준으로 이벤트 로그에 있는 엔트리를 가져옵니다.

메서드

CopyTo(EventLogEntry[], Int32)	특정 배열 인덱스부터 시작하여 EventLogEntryCollection 요소를 EventLogEntry 인스턴스의 배열에 복사합니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetEnumerator()	EventLogEntryCollection 개체의 단순 반복을 지원합니다.
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)

명시적 인터페이스 구현

ICollection.CopyTo(Array, Int32)	특정 Array 인덱스부터 시작하여 컬렉션의 요소를 Array에 복사합니다.
ICollection.IsSynchronized	EventLogEntryCollection에 대한 액세스가 동기화되어 스레드로부터 안전하게 보호되는지를 나타내는 값을 가져옵니다.
ICollection.SyncRoot	EventLogEntryCollection 개체에 대한 액세스를 동기화하는 데 사용할 수 있는 개체를 가져옵니다.
