WizardStepCollection.CopyTo(WizardStepBase[], Int32) 方法

  • 參考

定義

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

從目標陣列的指定索引開始，複製 WizardStepCollection 集合的所有項目至 WizardStepBase 物件的相容一維陣列。

public:
 void CopyTo(cli::array <System::Web::UI::WebControls::WizardStepBase ^> ^ array, int index);
public void CopyTo (System.Web.UI.WebControls.WizardStepBase[] array, int index);
member this.CopyTo : System.Web.UI.WebControls.WizardStepBase[] * int -> unit
Public Sub CopyTo (array As WizardStepBase(), index As Integer)

參數

array
WizardStepBase[]

WizardStepBase 物件之以零起始的陣列，接收複製自集合之項目。

index
Int32

目標陣列中開始接收複製項目的位置。

範例

下列範例示範如何使用 CopyTo 方法，將 物件從集合複製到 WizardStepBase 陣列。 接著會逐一查看陣列，以顯示 ID 每個 WizardStepBase衍生物件的屬性。 請注意，在範例中， WizardSteps 控件的 Wizard 屬性是 類別 WizardStepCollection 的實例。

備註

CopyTo使用方法，將集合的內容複製到指定的以零起始的陣列中。 專案會從目標陣列的指定索引開始複製。 項目在陣列中之後，您可以使用數位語法來存取集合中的 WizardStepCollection 專案。

或者，您也可以使用 GetEnumerator 方法來建立列舉值，以用來存取集合中的專案。
