Question

i have created the folloiwng view model class

public class viewmodelclass
{
    public IEnumerable<Question> Questions { get; set; }
    public decimal Total { get; set; }
    public string Message { get; set; }

}

then i wrote the following method to create viewmodelclassobjects in my repository model class:-

public IQueryable<viewmodelclass> d (int number)
    { var q_t =  new viewmodelclass()
    {
            Message = "This question current;y have" + number,
            Total = number,
            Questions = from question123 in entities1.Questions
                               where question123.QuestionID >= number
                               select question123
        };
 return q_t;}

which will be called using the following method inside my controller class:-

 public ActionResult dd (int number = 0)
    { var q2 = elearningrepository.d(number);
        return View(q2);}

but i am receiving the following error on *return q_t*:-
Cannot implicitly convert type ‘Esystem.ViewModels.viewmodelclass’ to ‘System.Linq.IQueryable’. An explicit conversion exists (are you missing a cast?)
so how i can overcome this error ?

Answer 1

Modify the “d” method to return just the viewmodelclass

public viewmodelclass d (int number)
    { var q_t =  new viewmodelclass()
    {
            Message = "This question current;y have" + number,
            Total = number,
            Questions = from question123 in entities1.Questions
                               where question123.QuestionID >= number
                               select question123
        };
 return q_t;}

Modify your view to expect a viewmodelclass as its model.
you really don’t have to pass an IQueryable in this instance.
