public List<Contractor> getContractor()

        {

            IDatabase x = new Methods("SELECT x FROM XX");

            SqlDataReader Reader = (SqlDataReader)x.ExecuteReader();

 

            return (List<Contractor>)DatabaseToContractor(Reader);

 

        }


که کلاس Contractor می تونه به صورت زیر باشه



 

[DataContract()]

    public class Customer

    {



        private string _firstName;

        private DateTime _dateOfBirth;

        private DateTime _someOtherDate = DateTime.Now;

        private bool _isDirty = true;

     

        [DataMember]

        public string FirstName

        {

            get { return _firstName; }

            set { _firstName = value; }

        }



  private DateTime DateOfBirth

        {

            get { return _dateOfBirth; }

            set { _dateOfBirth = value; }

        }



        [DataMember(IsRequired=true)]

        private DateTime SomeOtherDate

        {

            get { return _someOtherDate; }

            set { _someOtherDate = value; }

        }



        public bool IsDirty

        {

            get { return _isDirty; }

            set { _isDirty = value; }

        }



    }


حالا شما می تونید List<Customer> تعریف کنید
