将对象序列化为Json

Question

I'm attempting to serialize an object as Json. The error returned by the code below is "An instance of type string cannot be assigned to a variable of type JsonResult". Can someone explain what I've done wrong? I thought serialize() accepts an object and that's what I am passing it.

    public class SummaryStats
    {
        public int rating_number { get; set; }
        public string rating_label { get; set; }
        public string rating_view { get; set; }
        public int max_stars { get; set; }
        public int star_1_rating { get; set; }
        public int star_2_rating { get; set; }
        public int star_3_rating { get; set; }
        public int star_4_rating { get; set; }
        public int star_5_rating { get; set; }
    }
    public JsonResult GetSummaryStats()
    {
        SummaryStats stats = new SummaryStats();
        stats.star_1_rating = 1;
        stats.star_2_rating = 1;
        stats.star_3_rating = 1;
        stats.star_4_rating = 11;
        stats.star_5_rating = 20;



        JavaScriptSerializer json = new JavaScriptSerializer();
        JsonResult output = json.Serialize(stats);

        return output;

    }

Answer 1

Assuming this is within a Controller derivative, just do:

return Json(stats);

The rest is handled for you.

Answer 2

Try Serializing your class :

[Serializable()]        
public class SummaryStats
{
...
}
