예제

다음 코드 예제에서는 검색 IToolboxService 하려고 합니다 때 컨트롤 디자인 모드에 배치 됩니다. 이 IToolboxService 검색되면 코드는 각 도구 상자 범주의 이름을 가져오고 컨트롤의 표면에 각 이름을 그립니다.

설명

이 컬렉션은 도구 상자 범주 이름의 컬렉션을 저장하는 데 사용됩니다.

생성자

CategoryNameCollection(CategoryNameCollection)	지정된 컬렉션을 사용하여 CategoryNameCollection 클래스의 새 인스턴스를 초기화합니다.
CategoryNameCollection(String[])	지정된 이름 배열을 사용하여 CategoryNameCollection 클래스의 새 인스턴스를 초기화합니다.

속성

Count	ReadOnlyCollectionBase 인스턴스에 포함된 요소 수를 가져옵니다. (다음에서 상속됨 ReadOnlyCollectionBase)
InnerList	ReadOnlyCollectionBase 인스턴스에 포함된 요소의 목록을 가져옵니다. (다음에서 상속됨 ReadOnlyCollectionBase)
Item[Int32]	지정된 인덱스의 범주 이름을 가져옵니다.

메서드

Contains(String)	지정된 범주가 컬렉션에 포함되는지 여부를 지정합니다.
CopyTo(String[], Int32)	지정된 인덱스의 지정된 배열에 컬렉션 요소를 복사합니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetEnumerator()	ReadOnlyCollectionBase 인스턴스를 반복하는 열거자를 반환합니다. (다음에서 상속됨 ReadOnlyCollectionBase)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
IndexOf(String)	지정된 값의 인덱스를 가져옵니다.
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
