定義

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

初始化 CircleHotSpot 類別的新執行個體。

public:
 CircleHotSpot();
public CircleHotSpot ();
Public Sub New ()

範例

下列程式代碼範例示範如何以程式設計方式建立兩個 CircleHotSpot 對象、設定其屬性，並將其新增至 ImageMap 控件的 HotSpotCollection。 若要讓這個範例正常運作，您必須提供屬性自己的映像 ImageUrl ，並適當地更新映像的路徑，讓應用程式可以找到它。
