HtmlTableCellCollection.CopyTo(Array, Int32) 方法

定义

HtmlTableCellCollection 中的指定索引开始,将 Array 集合中的项复制到指定的 ArrayCopies the items from the HtmlTableCellCollection collection to the specified Array, beginning with the specified index in the Array.

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

参数

array
Array

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

index
Int32

指定 Array 中接收项的第一个索引。The first index in the specified Array to receive the items.

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HtmlTableCellCollection集合相同的内容的数组。The following code example demonstrates how to use the CopyTo method to create an array that contains the same contents as the HtmlTableCellCollection collection. 然后循环访问该数组, 以显示HtmlTableCellCollection集合的内容。The array is then iterated through to display the contents of the HtmlTableCellCollection collection.

注解

使用此方法可以从数组的指定索引HtmlTableCellCollection处开始, 将System.Array集合的内容复制到指定的中。Use this method to copy the contents of the HtmlTableCellCollection collection into the specified System.Array, starting at the specified index of the array.

备注

参数必须是从零开始System.Array的。 arrayThe array parameter must be a zero-based System.Array.
