TabPage.ImageIndex プロパティ
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As TabPage Dim value As Integer value = instance.ImageIndex instance.ImageIndex = value
/** @property */ public int get_ImageIndex () /** @property */ public void set_ImageIndex (int value)
タブに表示される TabControl.ImageList のイメージの 0 から始まるインデックス番号。既定値は -1 です。これはイメージがないことを示します。



1 つの TabPage がある TabControl を作成するコード例を次に示します。この例では、ImageIndex プロパティを使用して、myImages のどのイメージを tabPage1 のタブに表示するかを指定しています。
この例では、System.Drawing、System.ComponentModel、System.Windows.Forms、System.Resources の各名前空間を使用します。
