Assembly: System.Web (in system.web.dll)

public void CopyTo (
	GridViewRow[] array,
	int index
)
public void CopyTo (
	GridViewRow[] array, 
	int index
)
public function CopyTo (
	array : GridViewRow[], 
	index : int
)
Not applicable.

Parameters

array

A zero-based System.Array object that receives the copied items from the GridViewRowCollection object.

index

The first index in the specified System.Array object to receive the copied contents.

Use this method to copy the items in the GridViewRowCollection object into the specified System.Array object, starting at the specified index. The System.Array object can then be used to access the items in the collection.

NoteNote:

You must use a zero-based System.Array object for the array parameter.

The following example demonstrates how to use the CopyTo method to copy the items of collection into an array. The array is iterated through and the values of the first cell are displayed on the page.
