Hi,

Can you try the following?

old_dt.AsEnumerable().GroupBy(Function(r) Tuple.Create(r("column1"),r("column2"))).Select(Function(g) g.First).CopyToDataTable

OR

old_dt.AsEnumerable().GroupBy(Function(r) Tuple.Create(r("column1").ToString,r("column2").ToString)).Select(Function(g) g.First).CopyToDataTable

Regards,
