  • 參考

定義

命名空間:
System.Web.UI.WebControls.WebParts
組件:
System.Web.dll

將 WebPartDisplayMode 物件加入至集合。

public:
 int Add(System::Web::UI::WebControls::WebParts::WebPartDisplayMode ^ value);
public int Add (System.Web.UI.WebControls.WebParts.WebPartDisplayMode value);
member this.Add : System.Web.UI.WebControls.WebParts.WebPartDisplayMode -> int
Public Function Add (value As WebPartDisplayMode) As Integer

參數

value
WebPartDisplayMode

要加入至集合的 WebPartDisplayMode。

傳回

Int32

整數值，表示 WebPartDisplayMode 在集合中的插入位置。

範例

此程式碼範例示範 類別的使用 WebPartDisplayModeCollection 。 如需執行範例所需的完整程式碼和指示，請參閱類別概觀的 WebPartDisplayModeCollection 一節。

下列程式碼區段發生在會覆寫 方法的衍生 WebPartManager 類別中 CreateDisplayModes ，並將自訂顯示模式新增至集合。

備註

您可以使用 Add 方法，將新的 WebPartDisplayMode 物件新增至現有的 WebPartDisplayModeCollection 物件。

您可以執行此動作的案例範例是當您建立自訂 WebPartDisplayMode 類別，並想要將它新增至頁面上支援的顯示模式集合。 若要這樣做，您必須繼承自 WebPartManager 類別並覆寫其 CreateDisplayModes 方法，先呼叫基底方法，然後使用 Add 方法將自訂顯示模式新增至集合。
