HotSpotCollection.Insert(Int32, HotSpot) 方法

  • 參考

定義

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

將指定的 HotSpot 物件插入 HotSpotCollection 集合中指定的索引位置。

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)

參數

index
Int32

要加入 HotSpot 物件的所在處陣列索引。

spot
HotSpot

要新增到集合的 HotSpot 物件。

範例

下列程式碼範例示範如何以程式設計方式將兩 CircleHotSpot 個 ImageMap 物件新增至 控制項。 屬性 HotSpots 是用來存取 HotSpotCollection 集合。 方法 Add 會加入 Circle2 至集合。 方法 Insert 會在 的第一個專案 Circle2 前面新增 Circle1 至集合。 若要讓這個範例正常運作，您必須提供屬性自己的映射 ImageUrl ，並適當地更新映射的路徑，讓應用程式可以找到它。
