In This Topic

Copies DbLoaderColumn objects from the DbLoaderColumnCollection to the specified array.

Visual Basic
C#

'Declaration
 
Public Sub CopyTo( _
   ByVal array() As DbLoaderColumn, _
   ByVal index As Integer _
)

public void CopyTo( 
   DbLoaderColumn[] array,
   int index
)

Parameters

array: The array into which to copy the DbLoaderColumn objects.
index: The zero-based index of the array.

Example

The following example exports the DbLoaderColumnCollection to an array of Devart.Data.PostgreSql.PgSqlLoaderColumn 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 PgSqlLoaderColumnCollection myColumns
  // ...
  PgSqlLoaderColumn[] myColumnArray = new PgSqlLoaderColumn[(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 PgSqlLoaderColumnCollection myColumns
  ' ...
  Dim myColumnArray(2 * myColumns.Count - 1) As PgSqlLoaderColumn
  myColumns.CopyTo(myColumnArray, 0)
  myColumns.CopyTo(myColumnArray, myColumns.Count)
  myColumns.Clear()
  Return True
End Function 'DoubleYourColumns
