ImageList.Images プロパティ

このイメージリストの ImageList.ImageCollection を取得します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 Images As ImageCollection

Visual Basic (使用法)

Dim instance As ImageList
Dim value As ImageCollection

value = instance.Images

public ImageCollection Images { get; }

C++

public:
property ImageCollection^ Images {
    ImageCollection^ get ();
}

/** @property */
public ImageCollection get_Images ()

JScript

public function get Images
 () : ImageCollection

プロパティ値
イメージのコレクション。

解説

イメージのコレクションが作成されていない場合は、このプロパティを取得したときに作成されます。

使用例

ImageList を構築し、Images プロパティにイメージを追加し、ImageSize プロパティを設定して、Draw メソッドを使用するコード例を次に示します。この例を実行するには、Button1 という名前のボタンが配置されたフォームの中にこの例を配置します。この例では、c:\Windows\ に FeatherTexture.bmp および Gone Fishing.bmp が置かれていることを前提としています。これらのビットマップがシステムに存在しない場合、または他の場所に存在する場合は、必要に応じて例を変更してください。
