使用JSON.NET序列化公共属性

Question

I'm using JSON.NET implementation to serialize/deserialize .NET objects to JS and vice versa, all works fine until running GetWCFData() in the following:

using Newtonsoft.Json;
using Newtonsoft.Json.Converters;

    public class WebLookup
    {
        WCFService.WCFServiceClient svc;
        IsoDateTimeConverter DateConverter = new IsoDateTimeConverter();


        List<WCFContract.Language> Languages { get; set; }
        List<WCFContract.Group> Groups { get; set; }
        List<WCFContract.User> Users { get; set; }

        public WebLookup()
        {
            DateConverter.DateTimeFormat = "dd/MM/yyyy";
            DateConverter.DateTimeStyles = System.Globalization.DateTimeStyles.AssumeLocal;
        }

        public string GetWCFData()
        {
            svc = new WCFService.WCFServiceClient();
            WebLookup weblookup = new WebLookup();
            weblookup.Languages = svc.GetWCFLanguages().ToList();
            weblookup.Groups = svc.GetWCFGroups().ToList();
            weblookup.Users = svc.GetWCFUsers().ToList();

            return JsonConvert.SerializeObject(weblookup, DateConverter);
        } 

    }

Members Languages , Groups , and Users get populated successfully when calling the WCF service but JsonConvert.SerializeObject(lookup, DateConverter) always returns an empty JSON string to the client (web browser), this is strange as it usually works fine for me in other areas, the only difference is that here I have the populated WebLookup members declared as public properties in the class itself.

必须将Languages，Groups和Users属性声明为Public成员，才能通过JSON.NET或内置的JavaScriptSerializer进行序列化，但在您的代码中并非如此。
