Answer 1

Below method will search your needed keyword and insert all searched items into a new list and then returns new list.

private List serchForElement(string searchText, list ListOfitems)
{            
    searchText = searchText.ToLower();
    List Newlist = (from items in ListOfitems
                         where items.ToLower().Contains(searchText.ToLower())
                         select items).ToList(); 

return Newlist; }
