部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
將集合中 WizardStepCollection 的所有項目從目標陣列指定的索引開始,複製到相容的一維物件陣列 WizardStepBase 。
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[]
一個以零為基礎的物件陣列 WizardStepBase ,接收從集合複製的項目。
- index
- Int32
目標陣列中開始接收複製項目的位置。
範例
以下範例示範如何使用此 CopyTo 方法將集合中的物件複製 WizardStepBase 到陣列。 接著會遍歷陣列以顯示 ID 每個 WizardStepBase-導出物件的屬性。 請注意,在範例中, WizardSteps 控制的性質 Wizard 是類別的 WizardStepCollection 實例。

備註
使用該 CopyTo 方法將集合內容複製到指定的零為基礎陣列。 項目從目標陣列指定的索引開始複製。 當項目進入陣列後,你可以使用陣列語法來存取集合中的 WizardStepCollection 項目。
作為替代方案,你也可以使用此 GetEnumerator 方法建立一個列舉器,用來存取收藏中的項目。
