定義
重要
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。
將模組集合的成員複製到 Array (從陣列的指定索引處開始)。
public:
void CopyTo(Array ^ dest, int index);
public void CopyTo (Array dest, int index);
member this.CopyTo : Array * int -> unit
Public Sub CopyTo (dest As Array, index As Integer)
參數
範例
下列程式碼範例示範 AllKeys 類別的 HttpModuleCollection 屬性和 GetKey 和 CopyTo 方法。 此範例會從目前 HttpContext 物件取得目前要求的應用程式物件。 然後,它會從應用程式實例擷取 HttpModuleCollection 物件,並顯示物件的名稱 IHttpModule 。
