String.GetEnumerator 메서드
이 문자열의 개별 문자에서 반복될 수 있는 개체를 검색합니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Function GetEnumerator As CharEnumerator
‘사용 방법
Dim instance As String
Dim returnValue As CharEnumerator
returnValue = instance.GetEnumerator
public CharEnumerator GetEnumerator ()
public:
CharEnumerator^ GetEnumerator ()
public CharEnumerator GetEnumerator ()
public function GetEnumerator () : CharEnumerator
반환 값
CharEnumerator 개체입니다.
설명
이 메서드는 컬렉션 멤버에서 반복하도록 IEnumerator 인터페이스를 지원하는 프로그래밍 언어에 필요합니다. 예를 들어, Microsoft Visual Basic 및 C# 프로그래밍 언어에서 foreach 문은 이 메서드를 호출하여 String의 이 인스턴스에 포함된 문자에 대한 읽기 전용 액세스를 제공하는 CharEnumerator 개체를 반환합니다.
예제
다음 코드 예제에서는 GetEnumerator 메서드를 사용하여 각 System.Char를 입력 문자열에 표시합니다.
