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)

参数

array
Array

一个从零开始的 Array,它接收 HtmlTableRowCollection 的复制项。A zero-based Array that receives the copied items from the HtmlTableRowCollection.

index
Int32

实现

示例

下面的代码示例演示如何使用 CopyTo 方法创建一个包含与集合相同的内容的数组 HtmlTableRowCollectionThe following code example demonstrates how to use the CopyTo method to create an array that contains the same contents as the HtmlTableRowCollection collection. 然后循环访问该数组,以显示集合的内容。The array is then iterated through to display the contents of the collection.
