ASP.NET MVC w/ Newtonsoft passing objects from Controller to View

Question

I am trying to find the cleanest way to pass a object (recordset list) from the MVC 4 Controller to the View as a Json object.

Controller:

    var mem = BLL.Presenters.Account.GetAll().ToList();
    return View(mem);

View:

<script type="text/javascript">
    // Load data from view 
    var globalData = @(Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model)))
</script>

The javascript object has globalData which contains JSON.

Looking at the View, I am calling the Newtonsoft.Json.JsonConvert.SerializeObject, which I rather have in the Controller.

When I move the JsonConvert.SerializeObject to the Contoller:

   var mem = BLL.Presenters.Account.GetAll().ToList();
   var json = Newtonsoft.Json.JsonConvert.SerializeObject(mem);
   return View(json);

I get the error: Illegal characters in path.

How can I pass along a json object (already Serialize) from the Controller to the View using Newtonsoft.Json ?

I'd say your first approach is actually fine and more flexible e.g. if you ever added more data. — Yishai Galatzer

The compiler is misinterpretting your json (string) model as the name of a view and invoking the wrong overload of View. If you cast the model to object, you should be good to go:

return View((object)json)

return View(json); is actually calling method View(string viewName).

You need to put the json to the ViewData/ViewBag or ViewModel.
