通过

CircleHotSpot 构造函数

  • 参考

定义

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

初始化 CircleHotSpot 类的新实例。

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，并将其添加到 ImageMap 控件的 HotSpotCollection。 若要使此示例正常工作，必须为 属性提供自己的映像 ImageUrl ，并相应地更新映像的路径，以便应用程序能够找到它。
