Am using windows application
I have imported 50K rows from a CSV file to a datatable.  There may be some duplicate rows. I have one column "ISDUP" in the same datatable. i have to update the ISDUP column with True or False based on Duplicate row or not. When i find duplicate row i have to append the duplicate row in another datatable.

Here, the performence is most important thing.
