HotSpotCollection.Insert(Int32, HotSpot) 方法

定义

将指定的 HotSpot 对象插入到 HotSpotCollection 集合中的指定索引位置。Inserts a specified HotSpot object into the HotSpotCollection collection at the specified index location.

public:
 void Insert(int index, System::Web::UI::WebControls::HotSpot ^ spot);
public void Insert (int index, System.Web.UI.WebControls.HotSpot spot);
member this.Insert : int * System.Web.UI.WebControls.HotSpot -> unit
Public Sub Insert (index As Integer, spot As HotSpot)

参数

index
Int32

添加 HotSpot 对象的数组索引位置。The array index at which to add the HotSpot object.

spot
HotSpot

要添加到集合的 HotSpot 对象。The HotSpot object to add to the collection.

示例

下面的代码示例演示如何以编程方式将两个 CircleHotSpot 对象添加到 ImageMap 控件中。The following code example demonstrates how to programmatically add two CircleHotSpot objects to an ImageMap control. HotSpots属性用于访问 HotSpotCollection 集合。The HotSpots property is used to access the HotSpotCollection collection. Add方法将添加 Circle2 到集合中。The Add method adds Circle2 to the collection. Insert方法将添加 Circle1 到集合中第一个元素的前面 Circle2The Insert method adds Circle1 to the collection at the first element, in front of Circle2. 若要使此示例正常工作,必须为属性提供自己的图像 ImageUrl ,并适当地更新图像的路径,以便应用程序可以找到它。For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.
