How to retreive values of a dataset from BLL

Hello Experts,

I am working on job search web application written in asp.net 3.5 C#, which is a multitier application, I am facing a problem on how to access values return by a dataset in my Business logic layer which runs Stored Procedure and returns me emailaddress....

Here's my business logic file..

Subscribers.cs

namespace JobSite.BOL
{
    public class Subscribers
    {
        public Subscribers()
        {
        }
        private int strSubscriberID;
        private string strEmailAddress;
        private string strname;
        private string strCompany;
        private DateTime dtDateTimeStamp = DateTime.Now;


        public int SubscriberID
        {
            get
            {
                return strSubscriberID;
            }
            set
            {
                strSubscriberID = value;
            }
        }
        public string EmailAddress
        {
            get
            {
                return strEmailAddress;
            }
            set
            {
                strEmailAddress = value;
            }
        }

        public string name
        {
            get
            {
                return strname;
            }
            set
            {
                strname = value;
            }
        }

        public string Company
        {
            get
            {
                return strCompany;
            }
            set
            {
                strCompany = value;
            }
        }
        public DateTime DateTimeStamp
        {
            get
            {
                return dtDateTimeStamp;
            }
            set
            {
                dtDateTimeStamp = value;
            }
        }


        public int InsertSubscribers(Subscribers s)
        {
            DBAccess db = new DBAccess();
            //SqlParameter p = new SqlParameter();
            db.AddParameter("@EmailAddress", s.EmailAddress);
            db.AddParameter("@name", s.name);
            db.AddParameter("@Company", s.Company);
            db.AddParameter("@DateTimeStamp", s.DateTimeStamp);

            //db.AddParameter(p);
            return db.ExecuteNonQuery("NL_SubscribersInsert");

        }

       

//returns subscribers emailaddress
//***********************************************************
        public static DataSet GetSubscribersEmail()
        {
            DBAccess db = new DBAccess();
            return db.ExecuteDataSet("NL_Subscribers_SelectEmail");
        }

CODE Behind

Jobs.cs

protected void ObjectDataSource1_Inserted(object sender, ObjectDataSourceStatusEventArgs e)
    {
//***********************************************************
        string subscrEmail;

//ERRORRRRRRR       

JobSiteStarterKit.BOL.Subscribers subscription = Subscribers.GetSubscribersEmail();
//***********************************************************   

     
        if (e.Exception == null)
        {
            int id = (int)e.ReturnValue;
         
        MailMessage mailMessage = new MailMessage();
        mailMessage.From = new MailAddress("test@asp.com");
//***********************************************************       
mailMessage.To.Add(new MailAddress(subscrEmail.EmailAddress));

//***********************************************************
        mailMessage.Priority = MailPriority.High;
        mailMessage.IsBodyHtml = false;
        mailMessage.Subject = " New jobs uploaded example.com";
        mailMessage.Body = "this is a job alert";
        //Display confirmation message
       
        mailMessage.Body = "Please click the link below to view the job http://www.test.com/jobs.aspx?id=" + id + "";
        SmtpClient smtpClient = new SmtpClient();
        smtpClient.Send(mailMessage);
        }
