Remove duplicate in entry only one. I already tried Exists in Collection and List.Contains but seems doesn’t work.
Is your input type Datatable ? And do you want to delete duplicate rows from this Datatable ?
Correct. What im trying to do is identify this duplicate entries by storing to List.
If you want to delete duplicate entries from Datatable then try below expression.
yourDT.DefaultView.ToTable(True, Column1, column2,..)
