Namespace: System.Web.UI.WebControls
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.



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


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.


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.

  void AuthorsGridView_RowCreated(Object sender, GridViewRowEventArgs e)
    if (e.Row.RowType == DataControlRowType.Footer)
      Message.Text = "The authors are:<br />";
      // Copy the items in the Rows collection into an array.
      GridViewRow[] rowArray = new GridViewRow[AuthorsGridView.Rows.Count]; 
      AuthorsGridView.Rows.CopyTo(rowArray, 0);

      // Iterate though the array and display the value in the
      // first cell of the row.
      foreach(GridViewRow row in rowArray)
        Message.Text += row.Cells[0].Text + "<br />";
