NOTE: The array parameter must be a zero-based System.Array object.

The following example demonstrates how to use the CopyTo method to copy the contents of the DataColumnMappingCollection to an array of DataColumnMapping objects.

void copyTo ( DataTableMapping myTableMap ) {
   DataColumnMapping [ ] myArray = new DataColumnMapping [ 3 ];
   myTableMap.ColumnMappings.CopyTo ( myArray, 0 );

   foreach ( DataColumnMapping columnMap in myArray ) {
      myLabel.Text += columnMap.SourceColumn + "<br>";
   }
}

Sub copyTo ( ByVal myTableMap As DataTableMapping )
   Dim myArray ( 3 ) As DataColumnMapping
   myTableMap.Columns.CopyTo ( myArray, 0 )
   Dim columnMap As DataColumnMapping
   For Each columnMap In myArray
      myLabel.Text &= columnMap.HeaderText & "<br>"
   Next column 
End Sub
