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 -> unitPublic Sub CopyTo (array As Array, index As Integer)參數
- array
- Array
從 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。
實作
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 。
