DataTableFillerFill Method

public static void Fill(
	IDataReader dataSource,
	DataTable toFill,
	IFieldPersistenceInfo[] fieldsPersistenceInfo,
	IRetrievalQuery queryExecuted
)

Public Shared Sub Fill ( 
	dataSource As IDataReader,
	toFill As DataTable,
	fieldsPersistenceInfo As IFieldPersistenceInfo(),
	queryExecuted As IRetrievalQuery
)

DataReader isn't cleaned up afterwards. Call PersistenceCore.CleanupDataReader afterwards when you're done with the reader. This method is called in multiple situations: when toFill has all the columns needed, when toFill has no columns, when the resultset has more or less columns than required (e.g. stored proc resultset), and e.g. when everything matches perfectly. Therefore it has to check everything up front.
