HtmlTableRowCollection.CopyTo(Array, Int32) 方法

定義

將項目從 HtmlTableRowCollection 集合複製到指定的 Array 物件,從陣列中的指定索引處開始。

public:
 virtual void CopyTo(Array ^ array, int index);
public void CopyTo (Array array, int index);
abstract member CopyTo : Array * int -> unit
override this.CopyTo : Array * int -> unit
Public Sub CopyTo (array As Array, index As Integer)

參數

array
Array

HtmlTableRowCollection 接收複製項目的以零為起始的 Array

index
Int32

指定的陣列中要接受項目的第一個索引。

範例

下列程式碼範例示範如何使用 CopyTo 方法來建立陣列,其中包含與集合相同的內容 HtmlTableRowCollection 。 接著會逐一查看陣列以顯示集合的內容。

備註

使用這個方法,從陣列中的指定索引開始,將集合的內容 HtmlTableRowCollection 複製到指定的 System.Array 物件。

注意

參數 array 必須是以零起始 System.Array 的 。
