So I have 2 datatables with multiple columns and one is the main dt1 which I datascrape and it has multiple columns and rows which I need to check regarding rules which are in dt2. I also need to store these to some sort of collection if they meet the rules or not. How I should start working on this? Nested for each? Filter dt?

If Multiple Filter options is there then Filter DT can be used or for the Linq can be used for the Checking and store the required data in List.
