How to handle CopyToDataTable() when no rows?

Question

I have the code:

dt = collListItems.GetDataTable().AsEnumerable()
        .Where(a => Convert.ToString(a[\"Expertise\"]).Contains(expertise) && Co         


        

Answer 1

var results = from myRow in dtL1Users.AsEnumerable()
                                          where (Convert.ToInt32(myRow["No_x0020_of_x0020_L1_x0020_Remin"]) >= Convert.ToInt32(maxL1Escalation) && Convert.ToDateTime(myRow["L2_x0020_Last_x0020_Escalated_x0"]) < DateTime.Now.Date.AddDays(-Convert.ToInt32(reminderinterval)))
                                          select myRow;

                            foreach (var v in results)
                            {
                                collEligible = results.CopyToDataTable();
                                break;
                            }
