열거자가 다음 요소로 이동한 경우 true가 반환되고, 컬렉션의 끝을 지난 경우 false가 반환됩니다.
구현
예외
열거자가 만들어진 후에 컬렉션이 수정되었습니다.
예제
다음 코드 예제에서는 OidEnumerator 클래스를 사용하는 방법을 보여 줍니다.

설명
컬렉션 및 첫 번째 호출은 첫 번째 요소 앞 위치는 열거자를 만든 후의 MoveNext 메서드는 컬렉션의 첫 번째 요소를 통해 열거자를 이동 합니다. 에 대 한 후속 호출 MoveNext 지난 후속 항목 컬렉션의 열거자를 이동 합니다.
컬렉션의 끝이 전달 된 후 호출 MoveNext 반환 false합니다.
열거자는 컬렉션은 변경으로 유효 합니다. 변경에 추가 하는 등 컬렉션을 수정 하거나 유효 하지 않으며 다음 호출을 열거자가 요소를 삭제 하는 경우 MoveNext throw는 InvalidOperationException합니다.
