Select distinct rows in c# datatable on single column but return all columns

Question

DataView view = new DataView(dt);

If i have 2 columns "id" and "name" i need to get the distinct "id" but not the distinct "name" but i need to keep the column "name" in my datatable what shall i do?

Answer 1

DataView view = new DataView(table);
DataTable distinctValues = view.ToTable(true, "Column1", "Column2" ...);

If i have 2 columns "id" and "name" i need to get the distinct "id" but not the distinct "name" but i need to keep the column "name" in my datatable what shall i do?

OK, then i need grouping, not distinct.I could do it with Linq to DataSet: table.AsEnumerable().GroupBy(row => row.Field<int>("id")).Select(group =>group.First()).CopyToDataTable()
