We are not really able to see your goal here. It is possible using reflection to create generic method that will convert each data Table to a list of persistent classes but this wont give you any benefits. The problem here will be that the objects that you will transfer from the Data Tables wont be tracked by the object scope. You wont get any speed or optimizations in place and you wont be able to work with our objectscope at all. From our perspective it will make sense using data tables to move your data into the SQL Server (since you already have the database in place) and operate entirely using OpenAccess as this will bring you much benefits.
