嗨，当我尝试将我的模型从控制器传递到视图时出现问题，我不确定它是什么：

控制器（StatsController）：

  [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
    public ActionResult InterStats(int manufacturerId, int countryId, DateTime startDate, DateTime endDate)
    {

        //Get all manufacturerwidgets for manufacturer
        var manufacturerWidget = _manufacturerWidgetsRepository.GetManufacturerWidgetByManufacturerAndCountry(manufacturerId, countryId);
        var interReportJson = new InterReportJson();
        var interRecordList = new List<InterRecord>(); // a list of my anonymous type without the relationships
        interReportJson.InterRecordList = new List<InterRecord>();
        var count = 1;
        foreach (var mw in manufacturerWidget)
        {
            var widgetName = mw.Description;

            //Get the product stats data
            var imps = _productStatsRepository.GetSumImpressionsProductStatsForManufacturerCountryDate(
                mw.Id, countryId, startDate, endDate);


            var clicks = _productStatsRepository.GetSumClicksProductStatsForManufacturerCountryDate(
                mw.Id, countryId, startDate, endDate);

            float ctr = 0;
            if (imps != 0 && clicks != 0)
            {
                ctr = ((clicks / (float)imps) * 100);
            }



            //  Create the data for the report
            var interRecord = new InterRecord
            {
                WidgetName = widgetName,
                Impressions = imps,
                Interactions = clicks,
                Ctr = ctr,
                Count = count
            };




           interReportJson.InterRecordList.Add(interRecord);

            count++;
        }

        interReportJson.Counter = count;




        return PartialView(new InterReportJson());
    }

                        $("tr:even").css("background-color", "#eeeeee");
                        $("tr:odd").css("background-color", "#ffffff");

我在 Model.InterRecordList 上遇到错误，因为它认为它为空 - 我已经检查了控制器并且模型正在正确填充，但是当它到达视图时它已经失去了所有的价值。

我确定我遗漏了一些明显的东西，但任何帮助将不胜感激！

看来您不小心创建了一个新对象：

PartialView(new InterReportJson());

您可能的意思是使用现有的：PartialView(interReportJson);
