How Can I Give The The Bodyfat From { Var Jsondata= @Html.Raw(Json.Encode(Viewbag.List))} To Data:

public ActionResult DashBoard()
      {
          var user = repository.Get<ApplicationUser>(m => m.UserName == User.Identity.Name);

          ViewBag.List = repository.GetMany<TestResult>(m => m.TestInfoID == 3 && m.Username == User.Identity.Name).Select(n => new { TestDate = n.TestDate.ToString("yyyy-MM-dd"), BMI = Converter.CalculateBMI(user.Weight, true, user.Height, true).ToString("#.##"), BodyFat = Convert.ToDouble(n.Result).ToString("#.##"), FatWeight = Converter.CalculateFatWeight(user.Weight, Convert.ToDouble(n.Result)).ToString("#.##"), MuscleWeight = Converter.CalculateMuscleMass(user.Weight, Convert.ToDouble(n.Result)).ToString("#.##") });
