DataTable - Remove Duplicate Row

[Palaniyappan (Forum Leader)]

Hi
this expression could help you with
datatable = datatable.AsEnumerable().GroupBy(Function(a) a.Field(of string)(“yourcolumnnname”).ToString).Select(Function(b) b.First()).CopyToDatatable()

if you are not getting asenumberable then kindly have a view on this thread

AsEnumerable is not a member of 'System.Data.Datatable'

When trying to use the AsEnumerable() method on a data table, i receive a error stating that AsEnumerable is not a member of ‘System.Data.Datatable’. I’ve seen someone else with this problem and their solution was to use temporary data table activities in their project to load in the System.Data.DataSetExtension library. However this has not worked for me. Any help would be greatly appreciated. Thank you.
