CircleHotSpot 构造函数
定义
初始化 CircleHotSpot 类的新实例。Initializes a new instance of the CircleHotSpot class.
public:
CircleHotSpot();
public CircleHotSpot ();
Public Sub New ()
示例
下面的代码示例演示如何以编程方式创建两个 CircleHotSpot 对象,设置其属性,并将它们添加到 ImageMap 控件的 HotSpotCollection 。The following code example demonstrates how to programmatically create two CircleHotSpot objects, set their properties, and add them to the ImageMap control's HotSpotCollection. 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.
