次のコード例を作成、 ListView 3 つのコントロールListViewItem指定されたオブジェクトと 3 つListViewItem.ListViewSubItem項目ごとに指定されたオブジェクト。The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.ListViewSubItem objects specified for each item. 例でも作成ColumnHeader詳細ビューで、サブ項目を表示するオブジェクト。The example also creates ColumnHeader objects to display the subitems in details view. 2 つImageListオブジェクトが作成用のイメージを提供するコード例も、ListViewItemオブジェクト。Two ImageList objects are also created in the code example to provide images for the ListViewItem objects. これらImageListオブジェクトに追加されます、LargeImageListSmallImageListプロパティ。These ImageList objects are added to the LargeImageList and SmallImageList properties. 例では、作成するのには、次のプロパティを使用して、ListViewコントロール。The example uses the following properties in creating the ListView control.

この例にコードを追加することが必要です、Formコンス トラクターまたはフォーム上の別の方法の例で作成したメソッドを呼び出します。This example requires that you have added the code to a Form and call the method created in the example from the constructor or another method on the form. また、例ではイメージがという名前が必要ですMySmallImage1MySmallImage2MyLargeImage1、およびMyLargeImage2C: ドライブのルート ディレクトリにありますThe example also requires that images named MySmallImage1, MySmallImage2, MyLargeImage1, and MyLargeImage2 are located in the root directory of drive C.
