Question

A very new programmer to MVC, JSON & LINQ – I have created an ActionResult that returns a JSONResult:

var formhistory = from p in _formsRepository.ReturnedForms
                          where p.DateAdded >= DateTime.Now.Date.AddDays(-15) && p.DateAdded <= DateTime.Now.Date
                          group p by new {p.Centre, p.Form, p.DateAdded}
                          into g
                          select new {
                                         g.Key.Centre,
                                         g.Key.Form,
                                         g.Key.DateAdded,
                                         Total = g.Sum(p => p.Quantity)
                                     };
return Json(formhistory, JsonRequestBehavior.AllowGet);

This gives me a nice JSON result set as follows:

[
  {"Centre":"Centre1","Form":"Advice","DateAdded":"\/Date(1331856000000)\/","Total":1067},
  {"Centre":"Centre1","Form":"Advice","DateAdded":"\/Date(1332460800000)\/","Total":808},
  {"Centre":"Centre1","Form":"Advice","DateAdded":"\/Date(1333062000000)\/","Total":559},
  {"Centre":"Centre1","Form":"Advice","DateAdded":"\/Date(1333666800000)\/","Total":1448}
]

My question is this: I’m trying to manipulate this JSON string so that instead of 2 key/value pairs for “Form” and “Total” I only have 1, i.e. “Form”:”Total”.

I realise this is probably a very basic question, but can anyone point me in the correct direction? (Apart from the door!)

Answer 1

select new {
   g.Key.Centre,
   //g.Key.Form,
   g.Key.DateAdded,
   Form = g.Sum(p => p.Quantity)
}

would give you a key “Form” whose value is the former “Total”. Is that what you want?
