Datatable Delete Row based on Linq or Datatable.select

Hi All

I have a datatable with values
FAX Column name
“”
100
250
300
260
340
450
400
When we given the datatable .select based on removing data row

Dt3=DT2.Select(“FAX<>’’”).CopyToDatatable()

It Is getting sorted in ascending order
100
250
260
300
340
400
450

When we givn in linq query((From p In Dt2.Select
Where Not String.IsNullOrEmpty(String.Join(“string.Empty”,p.ItemArray))
Select p).ToArray.CopyToDataTable
FAX
100
250
300
260
340
450
400

May I know the difference between Linq query and datatable.select

I want to know why in select query It has to sort the data?

Thanks

Datatable.Select has a default ascending sort whereas LinQ doesnt inherently have it (you would use the Order By function)
