SearchValue = (from stp in SearchValue where stp.Description.Contains(_searchString) select stp).ToList<Serv>();

Answer 1

You have to use IndexOf + StringComparison.CurrentCultureIgnorecase :

SearchValue = SearchValue 
    .Where(sv => sv.Description.IndexOf(_searchString, StringComparison.CurrentCultureIgnoreCase) >= 0)
    .ToList();

Answer 2

You can use IndexOf which supports case-insensitive comparison:

SearchValue = (from stp in SearchValue
               where stp.Description.IndexOf(_searchString, 
                   StringComparison.InvariantCultureIgnoreCase) >= 0
               select stp).ToList<Serv>();

If you want a culture-aware comparison, you can use CurrentCultureIgnoreCase .
