  Get Circular reference serialized using Newtonsoft.json

  Dec 14, 2012 12:45 PM|LINK

  Hi All,

  I'm new to Web API and I've learned a lot throug forums and pluralsight-training. I'm developing a page to show large amount of data in a tabular form (project started with an Empty ASP.Net 4.0 Web Site, not a project or MVC application). 

  When I call apis which return data which has one or two properties in each row, it returns fine. But when I call an api which return large amount of data, a stack overflow exception is thrown. I assume this is due to circular references which I had problems withe before as well. Can someone please help me how to debug this or to solve this. I have the following global configurations setup.

  var config = GlobalConfiguration.Configuration;
          config.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
  
          config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
          
          config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Serialize;
          config.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
  
          // Code that runs on application startup
          // Code that runs on application startup
          RouteTable.Routes.MapHttpRoute(
              name: "DefaultApi",
              routeTemplate: "api/{controller}/{action}/{id}",
              defaults: new { id = System.Web.Http.RouteParameter.Optional }
          );

  Any help really appreciated.

  Thanks,
  Amila
