從 HtmlTableRowCollection 集合中複製項目到指定 Array 物件,從陣列中指定的索引開始。
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
一個以零為Array基礎的 ,會從 中接收複製的項目。HtmlTableRowCollection
- index
- Int32
指定陣列中的第一個索引,用來接收這些項目。
實作
範例
以下程式碼範例示範如何使用此 CopyTo 方法建立包含與集合相同內容 HtmlTableRowCollection 的陣列。 接著會遍歷陣列以顯示集合的內容。

備註
使用此方法將集合內容 HtmlTableRowCollection 從陣列中指定的索引開始複製到指定 System.Array 物件中。
Note
參數 array 必須是零為基礎 System.Array的 。
