Deserialize JSON array(or list) in C#
This code works for me:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Script.Serialization;
namespace Json
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(DeserializeNames());
Console.ReadLine();
}
public static string DeserializeNames()
{
var jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}";
JavaScriptSerializer ser = new JavaScriptSerializer();
nameList myNames = ser.Deserialize<nameList>(jsonData);
return ser.Serialize(myNames);
}
//Class descriptions
public class name
{
public string last { get; set; }
}
public class nameList
{
public List<name> name { get; set; }
}
}
}
Download Json.NET from here http://james.newtonking.com/projects/json-net.aspx
name deserializedName = JsonConvert.DeserializeObject<name>(jsonData);
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,
"genre": "Drama",
"genreList": [
"Drama"
],
"genres": [
{
"personName": "Drama"
}
],
"id": 1204,
"language": "Hindi",
"name": "The Great Target",
"productId": 1204,
"productMasterId": 1203,
"productMasterName": "The Great Target",
"productName": "The Great Target",
"productTypeId": 1,
"productTypeName": "Movie",
"rating": 3,
"releaseyear": "2005",
"showGoodName": "Movies ",
"views": 8333
},
{
"channelType": "",
"duration": "2:30:30",
"episodeno": 0,
"genre": "Romance",
"genreList": [
"Romance"
],
"genres": [
{
"personName": "Romance"
}
],
"id": 1144,
"language": "Hindi",
"name": "Mere Sapnon Ki Rani",
"productId": 1144,
"productMasterId": 1143,
"productMasterName": "Mere Sapnon Ki Rani",
"productName": "Mere Sapnon Ki Rani",
"productTypeId": 1,
"productTypeName": "Movie",
"rating": 3,
"releaseyear": "1997",
"showGoodName": "Movies ",
"views": 6482
},
{
"channelType": "",
"duration": "2:34:07",
"episodeno": 0,
"genre": "Drama",
"genreList": [
"Drama"
],
"genres": [
{
"personName": "Drama"
}
],
"id": 1520,
"language": "Telugu",
"name": "Satyameva Jayathe",
"productId": 1520,
"productMasterId": 1519,
"productMasterName": "Satyameva Jayathe",
"productName": "Satyameva Jayathe",
"productTypeId": 1,
"productTypeName": "Movie",
"rating": 3,
"releaseyear": "2004",
"showGoodName": "Movies ",
"views": 9910
}
],
"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>
/// Summary description for Class3
/// </summary>
public class Class3
{
public List<ListWrapper_Main> ResultList_Main { get; set; }
public class ListWrapper_Main
{
public List<ListWrapper> 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_cls> 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<Class3.ListWrapper_Main> movieInfos = ser.Deserialize<List<Class3.ListWrapper_Main>>(final_sb.ToString());
foreach (var itemdetail in movieInfos)
{
foreach (var itemdetail2 in itemdetail.ResultList)
{
Response.Write("channelType=" + itemdetail2.channelType + "<br/>");
Response.Write("duration=" + itemdetail2.duration + "<br/>");
Response.Write("episodeno=" + itemdetail2.episodeno + "<br/>");
Response.Write("genre=" + itemdetail2.genre + "<br/>");
string[] genreList_arr = itemdetail2.genreList;
for (int i = 0; i < genreList_arr.Length; i++)
Response.Write("genreList1=" + genreList_arr[i].ToString() + "<br>");
foreach (var genres1 in itemdetail2.genres)
{
Response.Write("genres1=" + genres1.personName + "<br>");
}
Response.Write("id=" + itemdetail2.id + "<br/>");
Response.Write("imageUrl=" + itemdetail2.imageUrl + "<br/>");
//Response.Write("imageurl=" + itemdetail2.imageurl + "<br/>");
Response.Write("language=" + itemdetail2.language + "<br/>");
Response.Write("name=" + itemdetail2.name + "<br/>");
Response.Write("productId=" + itemdetail2.productId + "<br/>");
Response.Write("productMasterId=" + itemdetail2.productMasterId + "<br/>");
Response.Write("productMasterName=" + itemdetail2.productMasterName + "<br/>");
Response.Write("productName=" + itemdetail2.productName + "<br/>");
Response.Write("productTypeId=" + itemdetail2.productTypeId + "<br/>");
Response.Write("productTypeName=" + itemdetail2.productTypeName + "<br/>");
Response.Write("rating=" + itemdetail2.rating + "<br/>");
Response.Write("releaseYear=" + itemdetail2.releaseYear + "<br/>");
//Response.Write("releaseyear=" + itemdetail2.releaseyear + "<br/>");
Response.Write("showGoodName=" + itemdetail2.showGoodName + "<br/>");
Response.Write("views=" + itemdetail2.views + "<br/><br>");
//Response.Write("resultSize" + itemdetail2.resultSize + "<br/>");
// Response.Write("pageIndex" + itemdetail2.pageIndex + "<br/>");
}
Response.Write("resultSize=" + itemdetail.resultSize + "<br/><br>");
Response.Write("pageIndex=" + itemdetail.pageIndex + "<br/><br>");
}
'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...
