プロパティ値

AListBox.SelectedIndexCollectionコントロールで現在選択されている項目のインデックスを格納します。A ListBox.SelectedIndexCollection containing the indexes of the currently selected items in the control. 項目が現在選択されていない場合、空ListBox.SelectedIndexCollectionが返されます。If no items are currently selected, an empty ListBox.SelectedIndexCollection is returned.

次のコード例は、使用する方法を示します、FindStringの項目の検索文字列のすべてのインスタンスを検索する方法、ListBoxします。The following code example demonstrates how to use the FindString method to search for all instances of the search text in the items of the ListBox. 例では、バージョンを使用して、FindStringメソッド内のすべての項目の継続的な検索を実行する開始検索インデックスを指定することができます、ListBoxします。The example uses the version of the FindString method that enables you to specify a starting search index from which to do a continual search of all items in the ListBox. 例では、タイミングを決定する方法も示しています、FindStringメソッドは、再帰的な検索を防ぐために項目の一覧の下部に達した後の一覧の先頭から検索を開始します。The example also demonstrates how to determine when the FindString method begins searching from the top of the list after it reaches the bottom of the list of items to prevent a recursive search. 項目が見つかると、ListBoxを使用して、選択したが、SetSelectedメソッド。Once items are found in the ListBox, they are selected using the SetSelected method.

注釈

複数選択のListBox、このプロパティで選択されているすべての項目のインデックスを含むコレクションを返します、ListBoxします。For a multiple-selection ListBox, this property returns a collection containing the indexes to all items that are selected in the ListBox. 単一選択のListBox、このプロパティの唯一の選択した項目のインデックスを含む 1 つの要素を含むコレクションを返します、ListBoxします。For a single-selection ListBox, this property returns a collection containing a single element containing the index of the only selected item in the ListBox. コレクションのアイテムを操作する方法の詳細については、次を参照してください。ListBox.SelectedIndexCollectionします。For more information about how to manipulate the items of the collection, see ListBox.SelectedIndexCollection.

ListBoxクラスには、さまざまな選択した項目を参照する方法が用意されています。The ListBox class provides a number of ways to reference selected items. 使用する代わりに、SelectedIndices単一選択で現在選択されている項目のインデックス位置を取得するプロパティListBox、使用することができます、SelectedIndexプロパティ。Instead of using the SelectedIndices property to obtain the index position of the currently selected item in a single-selection ListBox, you can use the SelectedIndex property. 現在選択されている項目を取得する場合、 ListBox、項目のインデックス位置ではなくを使用して、SelectedItemプロパティ。If you want to obtain the item that is currently selected in the ListBox, instead of the index position of the item, use the SelectedItem property. さらに、使用、SelectedItems複数選択で選択されたすべての項目を取得する場合はプロパティListBoxします。In addition, you can use the SelectedItems property if you want to obtain all the selected items in a multiple-selection ListBox.
