Question

public class JsonCategoriesDisplay
    {
        public JsonCategoriesDisplay() { }

        public int CategoryID { set; get; }
        public string CategoryTitle { set; get; }
    }

    public class ArticleCategoryRepository
    {
        private DB db = new DB();  

        public IQueryable<JsonCategoriesDisplay> JsonFindAllCategories()
        {
            var result = from c in db.ArticleCategories                         
                         select new JsonCategoriesDisplay
                         {
                             CategoryID = c.CategoryID,
                             CategoryTitle = c.Title                            
                         };

            return result;
        }

          ....
    }

public class ArticleController : Controller
    {
        ArticleRepository articleRepository = new ArticleRepository();
        ArticleCategoryRepository articleCategoryRepository = new ArticleCategoryRepository();


        public string Categories()
        {
            var jsonCats = articleCategoryRepository.JsonFindAllCategories().ToList();

            //return Json(jsonCats, JsonRequestBehavior.AllowGet);

            return new JavaScriptSerializer().Serialize(new { jsonCats});
        }

    }

This results with following:

{"jsonCats":[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]}

If I use line that is commented and place JsonResult instead of returning string, I get following result:<

[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]

But, I need result to be formatted like this:

{'2':'Politika','3':'Informatika','4':'Nova
kateorija','5':'Testna kategorija'}

Is there a simple way to accomplish this or I will need to hardcode result?

Answer 1

Have a look at the Json.Net library

The Json.NET library makes working
with JavaScript and JSON formatted
data in .NET simple. Quickly read and
write JSON using the JsonReader and
JsonWriter or serialize your .NET
objects with a single method call
using the JsonSerializer.

I have successfully used it within a .net mvc project.
