EditorPartCollection.CopyTo(EditorPart[], Int32) 方法

  • 参考

定义

命名空间:
System.Web.UI.WebControls.WebParts
程序集:
System.Web.dll

将集合复制到 EditorPart 控件的数组。

public:
 void CopyTo(cli::array <System::Web::UI::WebControls::WebParts::EditorPart ^> ^ array, int index);
public void CopyTo (System.Web.UI.WebControls.WebParts.EditorPart[] array, int index);
member this.CopyTo : System.Web.UI.WebControls.WebParts.EditorPart[] * int -> unit
Public Sub CopyTo (array As EditorPart(), index As Integer)

参数

array
EditorPart[]

要包含被复制控件集合的 EditorPart。

index
Int32

在数组中放置集合内容的起始点。

示例

下面的代码示例演示如何使用 CopyTo 该方法创建自定义控件数组 EditorPart 。 有关运行示例所需的完整代码，请参阅类概述的示例 EditorPartCollection 部分。

事件中的 Button1_Click 代码创建控件数组 EditorPart ，将 LayoutEditorPart1 控件添加到数组，然后使用 CopyTo 该方法将控件从 EditorPartCollection 对象复制到数组。

在浏览器中加载页面时，可以通过在 “显示模式”下拉列表控件中选择“编辑”将页面切换到编辑模式。 可以在控件的标题栏中 TextDisplayWebPart 单击谓词菜单 (向下箭头) ，然后单击“ 编辑 ”以编辑控件。 编辑用户界面 (UI) 可见时，可以看到所有 EditorPart 控件。 如果单击“ 创建 EditorPartCollection ”按钮，你会注意到自定义数组中所有控件的标题列在页面底部附近。

注解

CopyTo如果想要创建自定义数组，该数组可以包含EditorPart对象中的EditorPartCollection控件、这些控件的子集或这些控件的超集，则此方法非常有用。
