how to make a service which reads and display data from sql table on client side in wcf

namespace datafromdbservice
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        dataret GetData(int id);       

        // TODO: Add your service operations here
    }

    // Use a data contract as illustrated in the sample below to add composite types to service operations.

    [DataContract]
    public class dataret
    {
       [DataMember]
        public string name
        {
            get { return name; }
            set { name = value; }
        }

        [DataMember]
        public int personid
        {
            get { return personid; }
            set { personid = value; }
        }
        [DataMember]
        public DateTime hiredate { get; set; }
        [DataMember]
        public DateTime enrolldate { get; set; }
        [DataMember]
        public string discriminator { get; set; }
    }
}
//service1.svc.cs

 public class Service1 : IService1
    {
        SqlCommand cmd;
