TableCellCollection.CopyTo(Array, Int32) 方法
定义
从 TableCellCollection 中的指定索引开始,将 Array 中的项复制到指定的 Array。Copies the items from the TableCellCollection to the specified Array, starting 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
Public Sub CopyTo (array As Array, index As Integer)
参数
- array
- Array
一个从零开始的 Array,它接收 TableCellCollection 的复制项。A zero-based Array that receives the copied items from the TableCellCollection.
实现
示例
下面的示例演示如何使用方法将 CopyTo 中的项复制 TableCellCollection 到指定的数组中。The following example demonstrates how to use the CopyTo method to copy the items from the TableCellCollection into the specified array.

注解
使用此方法可将的内容 TableCellCollection System.Array 从指定的索引处开始复制到指定的中。Use this method to copy the contents of the TableCellCollection into the specified System.Array starting at the specified index.
备注
array参数必须是从零开始的 System.Array 。The array parameter must be a zero-based System.Array.
