在ASP.NET MVC中全局应用JSON Serializer设置

Question

当我的Entity Framework Navigation尝试序列化我的Kendo Grid中的集合时，View Model属性导致“循环对象引用”异常。我们正在使用Newtonsoft.JSON，所以我想（全局）在我的Application_Start()中将“ReferenceLoopHandling”设置为“Ignore”。

奇怪的是，ASP.NET似乎并不尊重设置...所以我仍然得到例外。

...有任何想法吗？

版本：

Microsoft.AspNet.Mvc（5.2.3.0）
Microsoft.AspNet.WebApi（5.2.3）
Newtonsoft.Json（10.0.3）

示例APPLICATION_START：转移到顶部或底部的调用不会改变结果......

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    LoadSiteMap();

    var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
    json.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
}

样品剃须标记：注意“BindTo”选项......

@(html.Kendo().Grid<RTUDeviceControlRoomAlarm>()
              .Columns(columns =>
              {
                  columns.Bound(x => x.Id)
                      .Visible(false);
                  columns.Bound(x => x.RTUDeviceId)
                      .Visible(false);
                  columns.Bound(x => x.Register)
                      .Title("Register")
                      .Width(50);
                  columns.Bound(x => x.Description)
                      .Title("Description")
                      .Width(100);
                  columns.Bound(x => x.LowLowLimitOFF)
                      .Title("LL Limit/OFF")
                      .Width(50);
                  columns.Bound(x => x.LowLowLimitON)
                      .Title("LL Limit/ON")
                      .Width(50);
                  columns.Bound(x => x.HiLimit)
                      .Title("Hi Limit")
                      .Width(50);
                  columns.Bound(x => x.HiHiLimit)
                      .Title("HH Limit")
                      .Width(50);
                  columns.Command(command => { command.Edit(); command.Destroy(); }).Width(70);
              })
              .Name("gridControlRoomAlarms")
              .ToolBar(toolbar => toolbar.Create())
              .Editable(editable => editable.Mode(GridEditMode.InLine))
              .Sortable()
              .Scrollable()
              .BindTo(Model.RTUDeviceControlRoomAlarms)
              .DataSource(dataSource => dataSource.Ajax()
                                                  .PageSize(50)
                                                  .Model(model => { model.Id(m => m.Id); })
                                                  .Create(update => update.Action("Create", "ControlRoomAlarm", new { Area = "Documents" }))
                                                  .Update(update => update.Action("Update", "ControlRoomAlarm", new { Area = "Documents" }))
                                                  .Destroy(update => update.Action("Destroy", "ControlRoomAlarm", new { Area = "Documents" }))
                                                  )
              .HtmlAttributes(new { @class = "", @style = "height: 400px;" }))

更新：也试过......

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
