Question

Is it possible …??? I have 4 DropDownLists on my main page and the
user may select from any, all or some of
the DropDownLists. I am capturing their selection (or non-selection) using a SESSION
variable. What I would like to be able to do is pass the session
variable values to my Data Access Layer and build a WHERE clause
(maybe using StringBuilder) and then place that variable SOMEHOW into
my query expression. Is that possible??? Sorry, I’m a newbie. Thanks ~susan~

public class DLgetRestaurants
    {
        FVTCEntities db = new FVTCEntities();

        public List<RESTAURANT> getRestaurants(string cuisineName, string priceName, string cityName)

        [Build a string based on the values passed to the function]

        {
            var cuisineID = db.CUISINEs.First(s => s.CUISINE_NAME == cuisineName).CUISINE_ID;

            List<RESTAURANT> result = (from RESTAURANT in db.RESTAURANTs.Include("CITY").Include("CUISINE").Include("Price") 
                                       where **[USE STRINGBUIDER EXPRSSION HERE]**
                                       select RESTAURANT).ToList();


             return result;
        }
    }

I have done this in the past using the Dynamic Linq Library.
