Question

I have a controller action which returns StudentID.

[HttpPost()]
    public ActionResult DisplayStudents()
    {
        StudentDataContext db = new StudentDataContext ();

        var StudentID = (from s in db.vwStudents.Where(s => s.StudentID != null)
                          group s by s.StudentID into g
                          select g.Key).ToList();

         return Json(new {StudentID});

    }

I want to return “StudentName” from the same view as well, but parse the final result and return “StudentID – StudentName” for e.g. “JD11212 – John Deat”

Is there a way where I can group two columns “StudentID” and “StudentName” in one and return that?

Answer 1

...
group s by new {s.StudentID, s.StudentName} into g
...

This will create a new anonymous type {StudentID, StudentName} which should be what you are looking for.
