예제

다음 예제에서는 선택한 항목을 열거하여 항목이 CheckedListBox.CheckedIndexCollection 있는 확인 상태를 확인합니다. 이 예제에서는 속성을 사용하여 CheckedIndices 해당 속성을 가져와 CheckedListBox.CheckedIndexCollectionCheckedItems 서 가져오는 방법을 CheckedListBox.CheckedItemCollection보여 줍니다.

첫 번째 루프는 항목의 GetItemCheckState 인덱스가 CheckState 지정된 경우 메서드를 사용하여 확인된 각 항목의 항목을 가져옵니다. 두 번째 루프도 사용 GetItemCheckState하지만 메서드를 ListBox.ObjectCollection.IndexOf 사용하여 항목의 인덱스도 검색합니다.
