Way to Deserialize JSON from HttpWebResponse

Question

I'm trying to figure out the best way to parse incoming JSON server-side in .NET 3.5. I am receiving "title" from HttpWebResponse in JSON Formate. so i have to retrieve each title and store in the database. so please provide the code for retrieving each title.

public class MyObject
{
    public ArrayList list { get; set; }
}

    var request = WebRequest.Create("https://api.dailymotion.com/videos?fields=description,thumbnail_medium_url%2Ctitle&search=Good+Morning");
    using (var twitpicResponse = (HttpWebResponse)request.GetResponse())
    {
        using (var reader = new StreamReader(twitpicResponse.GetResponseStream()))
        {
            JavaScriptSerializer js = new JavaScriptSerializer();
            string objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText, typeof(MyObject));
        }
    }

I am receiving Title in the myojb but how to retrieve Each Title from myojb.

use Dictionary in place of array list. OR you can deserialize it with object type first and then look at the data and create appropriate class — Prashant Lakhlani, Nov 07 '12 at 13:53

Use this piece of code snippet to get Title by using dynamic object.

.NET 4.0 and above

JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<dynamic>(reader.ReadToEnd());
foreach (var o in obj["list"])
{
    var title = o["title"];
}

.NET 3.5 and below

JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<Dictionary<string, object>>(reader.ReadToEnd());
foreach (var o in (ArrayList)obj["list"])
{
    if (o is Dictionary<string, object>)
        var title = (o as Dictionary<string, object>)["title"];
}

Using Linq:

JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<Dictionary<string, object>>(reader.ReadToEnd());
var titles = ((ArrayList)obj["list"]).Cast<Dictionary<string, object>>()
                 .Select(s => s["title"].ToString()).ToArray<string>();

.NET 3.5 not support dynamic object. Any alternative for the same — user1798345, Nov 07 '12 at 18:23

Serialize into a dynamic object

using (var reader = new StreamReader(twitpicResponse.GetResponseStream()))
{
    JavaScriptSerializer js = new JavaScriptSerializer();
    var objects = js.Deserialize<dynamic>(reader.ReadToEnd());
    foreach (var o in objects)
    {
        Console.WriteLine(o["title"]);
    }
}

I would use json.net. Its so easy to deserialize/serialize json data.

Have a look here:

How to post JSON to the server?
