   ByVal array() As DbLoaderColumn, _
   ByVal index As Integer _
)

Parameters

array: The array into which to copy the DbLoaderColumn objects.

Example

The following example exports the DbLoaderColumnCollection to an array of Devart.Data.Oracle.OracleLoaderColumn objects, doubles the size of the array by using CopyTo and returns the collection. It then clears the collection, and returns true if the columns are no longer persisting. This example assumes that a DbLoaderColumnCollection has already been created.

csharp

public bool DoubleYourColumns() {
  // ...
  // create OracleLoaderColumnCollection myColumns
  // ...
  OracleLoaderColumn[] myColumnArray = new OracleLoaderColumn[(2*myColumns.Count) - 1];
  myColumns.CopyTo(myColumnArray, 0);
  myColumns.CopyTo(myColumnArray, myColumns.Count);
  myColumns.Clear();
  return true;
}

Visual Basic

Public Function DoubleYourColumns() As Boolean
  ' ...
  ' create OracleLoaderColumnCollection myColumns
  ' ...
  Dim myColumnArray(2 * myColumns.Count - 1) As OracleLoaderColumn
  myColumns.CopyTo(myColumnArray, 0)
  myColumns.CopyTo(myColumnArray, myColumns.Count)
  myColumns.Clear()
  Return True
End Function 'DoubleYourColumns
