Examples

The following example uses the CopyTo method to export the collection to an array of DataTableMapping objects. It then clears the collection, and returns true if the parameters are no longer persisting. This example assumes that a DataTableMappingCollection has already been created.

public void PushIntoArray()
{
    // ...
    // create DataTableMappingCollection collection mappings
    // ...
    DataTableMapping[] tables = {};
    mappings.CopyTo(tables, 0);
    mappings.Clear();
}

Public Sub PushIntoArray()
    ' ...
    ' create DataTableMappingCollection collection mappings
    ' ...
    Dim tables() As DataTableMapping
    mappings.CopyTo(tables, 0)
    mappings.Clear()
End Sub
