How to return multiple values using json?

This is my script:

function UpdateFields() {

var StudentId = parseInt($('#@Html.IdFor(m => m.StudentId)').val());

var ProjectId= parseInt($('#@Html.IdFor(m => m.ProjectId)').val());

var Par = {

'StudentId ': StudentId ,

'ProjectId': ProjectId

};

$.ajax({

url: '@Url.Action("New")',

data: Par,

type: 'GET',

success: function (data) {

$('#@Html.IdFor(m => m.StudentId )').val(data);

$('#@Html.IdFor(m => m.ProjectId)').val(data);

error: function (request, status, error) {alert('error');

});

This is my action in my controller

public ActionResult New(StudentNewViewModel model)

{

model.LoadFromFields(SCPProvider, model.StudentId , model.ProjectId);

return Json(model.StudentId , JsonRequestBehavior.AllowGet);

}

My question is how can i return both StudentId and ProjectId with Json? so that these two fields can be updated dynamically when changes on form are made.

Use ViewModel class and include both the classes containing properties
StudentId and ProjectId.

Public Class VM
{

PUBLIC STUDENT student {get;set;}

public PROJECT project {get;set;}
}
