Solution 3

Try..

C#

class clsbo
{
    public List<string> hobbies{ get; set; }
}

C#

clsbo objbo= new clsbo();
objbo.hobbies = new List<string>();
foreach (ListItem li in CheckBoxList1.Items)
{
  if(li.Selected)
  {
    if (li.Value != null && li.Value != "")
    {
        objbo.hobbies.Add(li.Value);
    }
   }
}
