I have a datatable with two columns FromDate and ToDate , which are in string format.
I want to check if there are any duplicate records in my table.i.e
From Date To Date
----------------------
9/01/2012 9/16/2012
8/23/2012 8/24/2012
8/25/2012 8/25/2012
8/5/2012 8/6/2012
8/26/2012 8/27/2012
9/15/2012 9/23/2012
The table contains duplicate records as their date range is mapping for
From Date To Date
----------------------
9/01/2012 9/16/2012
9/15/2012 9/23/2012
It should return false.
