如何在ASP.NET MVC中将C#属性指定给Json对象？

Question

++ Model

    public class Product{
        public int ProductId { get; set; }
        public string ProductName { get; set; }

        public DataTable dt = new DataTable();
        public Category Category = new Category();
    }

++Controller

    public JsonResult Index(){
        Product dto = new Product();
        dto.ProductId = 1;
        dto.ProductName = "Coca Cola";
        return Json(dto, JsonRequestBehavior.AllowGet);
    }

如何指定Json对象，我的意思是只需要ProductId、ProductName等不需要Json对象。

++Want

    {
        "ProductId": 1,
        "ProductName": "Coca Cola"
    }

在序列化或反序列化时，可以对要从对象中排除的每个属性使用system.web.script.serialization中的[ScriptIgnore]属性：

  using System.Web.Script.Serialization;

  public class Product{
        public int ProductId { get; set; }
        public string ProductName { get; set; }

        [ScriptIgnore]
        public DataTable dt = new DataTable();
        [ScriptIgnore]
        public Category Category = new Category();
    }
