[2.0] Table relationships between dataTables in ado.net how???

I read an xml document into a Dataset. The dataset has 3 Datatables.

I want the data that exists in 2 datatables.

I need some help in queying these two datatables and storing the desired results into oracle table.

Data in the "CashFlows" datatable ( 3 fields in the datatable):

I35 0 0
I40 1 0
I45 2 0

Data in the "CF" datatable (3 fields in the datatable):

2000 JasonSmith 0
3000 Jerymith 0
4000 Johnperry 1
5000 kkkkkkkkkk 1
7000 westwood 2

I want to link these two datatables, based on second field from "Cashflows" data table and third field in the "CF" datatable. so the desired resultset should be :

I35 2000 JasonSmith
I40 3000 Jersmith
I45 4000 Johnperry

Can some one point me / direct me how to do this ?

For the relationship you just create a DataRelation, specifying the parent and child tables and columns. There's no in-built class that will perform a join of two DataTables though. You can use methods of the parent DataRows to get their child rows but you'd have to construct the resulting table yourself.
