how to store and retrieve Linq List into session variable in c#

This is how i am storing my linq list into session. How would I retrive it back from session

 DataClassesDataContext myContext = new DataClassesDataContext();

        var QuestionList = myContext.sp_GetQuestionsByChapterID(Session["QuizID"].ToString()).ToList();

        Session["QuestionsList"] = QuestionList;

I have tried something like this to retrive it back from session

var QuestionList=  Session["QuestionsList"] ;
int QuestionID = (int)QuestionList[CurrentPos].QuestionID;

this is giving me an error
"Cannot apply indexing with [] to an expression of type 'object'"

What would be the type of "QuestionList" ? Is it "List<Question>" ?

If "QuestionList" is "List<Question>", you can retrieve as follows

List<Question> questions = (List<Question>)Session["QuestionsList"];
int questionID = questions[CurrentPos].QuestionID;

thanks for comment
I store QuestionList  in var like this, var QuestionList  but using it as an arraylist. Can we convert the session into arraylist?

You can cast it like this:

ArrayList questionList =  (ArrayList)Session["QuestionsList"];
