Pass Parameter in MVC using a List

Question

I have an app for creating Exams. After creating a new question I would like to pass the question_id parameter to the questions_choices create action. I have created a list of questions choices to do 4 at a time (A, B, C, & D) in the action. I am having difficultly in passing the question_id into the list.

Controller:

    public ActionResult CreateNewChoice(int? id)
    {
        var questions_choices = new List<questions_choices>();

        for (int i = 0; i < 4; i++)
        {
            questions_choices.Add(new questions_choices());               
        }                 
        return View(questions_choices);
    }

I would like to implement something like this within the list but a little confused how.

questions_choices questions_choices = new questions_choices();
        questions_choices.questions_id = id;

Model

 public partial class questions_choices
{
    public long questions_choices_id { get; set; }
    public Nullable<int> questions_id { get; set; }
    public string questions_choices_value { get; set; }
    public string questions_choices_string { get; set; }  
}

If a put the two together I have issues with the variable being declared twice.

you mean you want to assign 1,2,3,4 to questions_id seperately? — Usman

you can try something like this

 public ActionResult CreateNewChoice(int? id)
    {
        var questions_choices = new List<questions_choices>();

        for (int i = 0; i < 4; i++)
        {
            questions_choices.Add(new questions_choices(){questions_id = id});               
        }                 
        return View(questions_choices);
    }

it will assign id of the parameter to the questions_id to all 4 questions

    public ActionResult CreateNewChoice(int? id)
    {
    var questions_choices = new List<questions_choices>();
    questions_choices Objquestion;
    for (int i = 0; i < 4; i++)
    {
        Objquestion = new questions_choices();
        Objquestion.questions_id = id;
        questions_choices.Add(Objquestion);               
    }                 
    return View(questions_choices);
    }
