ti ho fatto un piccolo esempio:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for BLL
/// </summary>
public class BLL
{
List<BLLItem> _list = new List<BLLItem>();
public BLL()
{
_list.Add(new BLLItem{Name="Marco", Surname="Leoncini"});
_list.Add(new BLLItem { Name = "aAessio", Surname = "Leoncini" });
}
public List<BLLItem> GetList()
{
return _list;
}
public void Update(BLLItem item, string mokValue)
{ }
}
public class BLLItem
{
public string Name { get; set; }
public string Surname { get; set; }
}
