Convert DataTable to List

I have a working code but I would like to convert a block of code into a class a just call the classs. See code below.
DataTable results = dataAccess.Billing.GetDataTable(selectQuery);

                // Convert Table to List
                List<Service> serviceLines = new List<Service>();
                serviceLines = (from DataRow dr in results.Rows
                                select new Service()
                                {
                                    MemberNbr = dr["MEMBER_NBR"].ToString(),
                                    AffNbr = dr["AFF_NBR"].ToString(),
                                    AmtAllowP = Convert.ToDecimal(dr["AMTALLOW_P"]),
                                    AmtCharge = Convert.ToDecimal(dr["AMTCHARGE"])
                                }).ToList();

Can I remove this block of code and make a class or constant in another file so it is easy to maintain and just call it?
