Answer 1

I was having the similar issue and solved by understanding the Classes in asp.net C#

I want to read following JSON string :

[
    {
        "resultList": [
            {
                "channelType": "",
                "duration": "2:29:30",
                "episodeno": 0,

                "genreList": [
                    "Drama"
                ],
                "genres": [
                    {
                        "personName": "Drama"
                    }
                ],

        ],
        "resultSize": 1171,
        "pageIndex": "1"
    }
]

My asp.net c# code looks like following

First, Class3.cs page created in APP_Code folder of Web application

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections;
using System.Text;
using System.IO;
using System.Web.Script.Serialization;
using System.Collections.Generic;

/// 

/// Summary description for Class3
/// 
public class Class3
{

    public List ResultList_Main { get; set; }

    public class ListWrapper_Main
    {
        public List ResultList { get; set; }

        public string resultSize { get; set; }
        public string pageIndex { get; set; }
    }

    public class ListWrapper
    {
        public string channelType { get; set; }
        public string duration { get; set; }
        public int episodeno { get; set; }
        public string genre { get; set; }
        public string[] genreList { get; set; }
        public List genres { get; set; }
        public int id { get; set; }
        public string imageUrl { get; set; }
        //public string imageurl { get; set; }
        public string language { get; set; }
        public string name { get; set; }
        public int productId { get; set; }
        public int productMasterId { get; set; }
        public string productMasterName { get; set; }
        public string productName { get; set; }
        public int productTypeId { get; set; }
        public string productTypeName { get; set; }
        public decimal rating { get; set; }
        public string releaseYear { get; set; }
        //public string releaseyear { get; set; }
        public string showGoodName { get; set; }
        public string views { get; set; }
    }
    public class genres_cls
    {
        public string personName { get; set; }
    }

}

Then, Browser page that reads the string/JSON string listed above and displays/Deserialize the JSON objects and displays the data

JavaScriptSerializer ser = new JavaScriptSerializer();


        string final_sb = sb.ToString();

        List movieInfos = ser.Deserialize>(final_sb.ToString());

        foreach (var itemdetail in movieInfos)
        {

            foreach (var itemdetail2 in itemdetail.ResultList)
            {
                Response.Write("channelType=" + itemdetail2.channelType + "
");
                Response.Write("duration=" + itemdetail2.duration + "
");
                Response.Write("episodeno=" + itemdetail2.episodeno + "
");
                Response.Write("genre=" + itemdetail2.genre + "
");

                string[] genreList_arr = itemdetail2.genreList;
                for (int i = 0; i < genreList_arr.Length; i++)
                    Response.Write("genreList1=" + genreList_arr[i].ToString() + "
");

                foreach (var genres1 in itemdetail2.genres)
                {
                    Response.Write("genres1=" + genres1.personName + "
");
                }

                Response.Write("id=" + itemdetail2.id + "
");
                Response.Write("imageUrl=" + itemdetail2.imageUrl + "
");
                //Response.Write("imageurl=" + itemdetail2.imageurl + "
");
                Response.Write("language=" + itemdetail2.language + "
");
                Response.Write("name=" + itemdetail2.name + "
");
                Response.Write("productId=" + itemdetail2.productId + "

                Response.Write("productMasterId=" + itemdetail2.productMasterId + "

                Response.Write("productMasterName=" + itemdetail2.productMasterName + "

                Response.Write("productName=" + itemdetail2.productName + "

                Response.Write("productTypeId=" + itemdetail2.productTypeId + "
");
                Response.Write("productTypeName=" + itemdetail2.productTypeName + "
");
                Response.Write("rating=" + itemdetail2.rating + "
");
                Response.Write("releaseYear=" + itemdetail2.releaseYear + "
");
                //Response.Write("releaseyear=" + itemdetail2.releaseyear + "
");
                Response.Write("showGoodName=" + itemdetail2.showGoodName + "
");
                Response.Write("views=" + itemdetail2.views + "

");
                //Response.Write("resultSize" + itemdetail2.resultSize + "
");
                //  Response.Write("pageIndex" + itemdetail2.pageIndex + "
");


            }



            Response.Write("resultSize=" + itemdetail.resultSize + "

");
            Response.Write("pageIndex=" + itemdetail.pageIndex + "

");

        }

'sb' is the actual string, i.e. JSON string of data mentioned very first on top of this reply

This is basically - web application asp.net c# code....

N joy...
