C# 无法创建转换为JSON的文件

我想做一些图表，基于我使用CodeFirst的类结果

我有课堂成绩

控制器的设计与实现

[HttpGet]
        public async Task<IActionResult> Results(string id)
        {
            if (string.IsNullOrEmpty(id))
            {
                return NotFound();
            }
            Patient patient = await _userManager.FindByIdAsync(id) as Patient;
            if (patient == null)
            {
                return NotFound();
            }
            List<IGrouping<string, Result>> results = _context.Results.Where(x => x.PatientId == id).GroupBy(z => z.GameName).ToList();
            ViewBag.Test = JsonConvert.SerializeObject(results);
            return View(results);
        }

请帮助我解决模型更改中的此错误，如：

   public class ResultChartModel
    {
        public string Surname { get; set; }

        public List<Result> Results { get; set; }
    }

到

希望能对你有所帮助。

他不懂这个新的JavaScriptSerializerHow我来解决它？@TravisBincle。很抱歉我犯了一个严重的错误。它是ASP.NETMVC而不是ASP.NETCore。所以我更新了我的答案。并使用Newtonsoft.Json。谢谢，错误消失了，但我的页面是空的。为什么会这样？我更新了我的查看页面，可能有问题吗？哦，那我失败了，我加了括号，非常感谢！
