Asp.Net Web Services ดึงข้อมูลจาก database แทน list ทำยังไงครับ

namespace WebApplication1
{
    /// <summary>
    /// Summary description for RemoteService
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    [System.Web.Script.Services.ScriptService]
    public class RemoteService : System.Web.Services.WebService
    {
        [WebMethod]
        public IEnumerable<Event> GetEvents(DateTime? start, DateTime? end)
        {
            DateTime now = DateTime.Now;
 
            return new List<Event>
            {
                new Event       //// ตรงนี้อยากให้ดึงออกมาจาก database แทน ครับ ทำได้หรือไม่ครับ
                {
                    EventId = 1001,
                    CalendarId = 1,
                    Title = "Vacation",
                    StartDate = now.AddDays(-20).AddHours(10),
                    EndDate = now.AddDays(-10).AddHours(15),
                    IsAllDay = false,
                    Notes = "Have fun",
                    MyCustomField1 = 1
                }
            };
        }
 
        [WebMethod]
        public Event Save(Event e)
        {
            // save to database
            // ...
 
            // update EventId with real db-assigned id                               
            // e.g e.EventId = 1; 
            return e;
        }
 
 
        [WebMethod]
        public void Update(Event e)
        {
            // update database
            // ...
        }
 
        [WebMethod]
        public void Delete(Event e)
        {
            // delete from database
            // ...
        }
    }
