Parsing JSON data with C#

Try JSON.Net, if you have not seen this it should help you.

Json.NET library makes working with
JSON formatted data in .NET simple.
Key features include a flexible JSON
serializer to for quickly converting
.NET classes to JSON and back again,
and LINQ to JSON for reading and
writing JSON.

Deserialization discussed here.

The quickest method of converting
between JSON text and a .NET object is
using the JsonSerializer. The
JsonSerializer converts .NET objects
into their JSON equivalent and back
again.

The basic code structure for deserialization is below – Target still needs to be filled out to capture the rest of the parsed data items with the appropriate type. The file mentioned json.txt contains your data from the URL above.

using System;
using System.IO;
using Newtonsoft.Json;

public class NameAndId
{
    public string name;
    public int id; 
}

public class Data
{
    public NameAndId[] data;
}

public class Target
{
    public string id;
    public NameAndId from;
    public Data likes;
}

public class Program
{
    static void Main(string[] args)
    {
        string json = File.ReadAllText(@"c:\temp\json.txt");
        Target newTarget = JsonConvert.DeserializeObject<Target>(json);
    }
}

Here is the first part of the JSON stream for reference:

{
   "id": "367501354973",
   "from": {
      "name": "Bret Taylor",
      "id": "220439"
   },
   "message": "Pigs run from our house in fear. Tonight, I am wrapping the pork tenderloin in bacon and putting pancetta in the corn.",
   "updated_time": "2010-03-06T02:57:48+0000",
   "likes": {
      "data": [
         {
            "id": "29906278",
            "name": "Ross Miller"
         },
         {
            "id": "732777462",
            "name": "Surjit Padham"
         },
