설명
클래스를 ConfigurationSectionCollection 사용하여 개체 컬렉션을 ConfigurationSection 반복합니다. 속성 또는 속성을 사용하여 이 개체 컬렉션에 SectionsSections 액세스할 수 있습니다.
클래스는 ConfigurationSectionCollection 클래스를 확장하는 ConfigurationSection 사용자 지정 형식을 만드는 데도 사용됩니다.
속성
| Count |
이 ConfigurationSectionCollection 개체에 있는 섹션의 수를 가져옵니다. |
| Count |
NameObjectCollectionBase 인스턴스에 포함된 키/값 쌍의 수를 가져옵니다. (다음에서 상속됨 NameObjectCollectionBase) |
| IsReadOnly |
NameObjectCollectionBase 인스턴스가 읽기 전용인지 여부를 나타내는 값을 가져오거나 설정합니다. (다음에서 상속됨 NameObjectCollectionBase) |
| Item[Int32] |
지정된 ConfigurationSection 개체를 가져옵니다. |
| Item[String] |
지정된 ConfigurationSection 개체를 가져옵니다. |
| Keys |
이 ConfigurationSection에개체에 있는 모든 ConfigurationSectionCollection 개체에 대한 키를 가져옵니다. |
| Keys |
NameObjectCollectionBase.KeysCollection 인스턴스의 모든 키를 포함하는 NameObjectCollectionBase 인스턴스를 가져옵니다. (다음에서 상속됨 NameObjectCollectionBase) |
메서드
명시적 인터페이스 구현
| ICollection.CopyTo(Array, Int32) |
대상 배열의 지정된 인덱스에서 시작하여 전체 NameObjectCollectionBase을 호환되는 1차원 Array에 복사합니다. (다음에서 상속됨 NameObjectCollectionBase) |
| ICollection.IsSynchronized |
NameObjectCollectionBase 개체에 대한 액세스가 동기화되어 스레드로부터 안전하게 보호되는지 여부를 나타내는 값을 가져옵니다. (다음에서 상속됨 NameObjectCollectionBase) |
| ICollection.SyncRoot |
NameObjectCollectionBase 개체에 대한 액세스를 동기화하는 데 사용할 수 있는 개체를 가져옵니다. (다음에서 상속됨 NameObjectCollectionBase) |
확장 메서드
| Cast<TResult>(IEnumerable) |
IEnumerable의 요소를 지정된 형식으로 캐스팅합니다. |
| OfType<TResult>(IEnumerable) |
지정된 형식에 따라 IEnumerable의 요소를 필터링합니다. |
| AsParallel(IEnumerable) |
쿼리를 병렬화할 수 있도록 합니다. |
| AsQueryable(IEnumerable) |
IEnumerable을 IQueryable로 변환합니다. |
