The following 2 examples make use of either

  1. JavaScriptSerializer under System.Web.Script.Serialization Or
  2. Json.Decode under System.Web.Helpers

Example 1: using System.Web.Script.Serialization

using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Web.Script.Serialization;

namespace Tests
{
    [TestClass]
    public class JsonTests
    {
        [TestMethod]
        public void Test()
        {
            var json = "{\"user\":{\"name\":\"asdf\",\"teamname\":\"b\",\"email\":\"c\",\"players\":[\"1\",\"2\"]}}";
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            dynamic jsonObject = serializer.Deserialize<dynamic>(json);

            dynamic x = jsonObject["user"]; // result is Dictionary<string,object> user with fields name, teamname, email and players with their values
            x = jsonObject["user"]["name"]; // result is asdf
            x = jsonObject["user"]["players"]; // result is object[] players with its values
        }
    }
}

Usage: JSON object to Custom C# object

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Web.Script.Serialization;
using System.Linq;

namespace Tests
{
    [TestClass]
    public class JsonTests
    {
        [TestMethod]
        public void TestJavaScriptSerializer()
        {
            var json = "{\"user\":{\"name\":\"asdf\",\"teamname\":\"b\",\"email\":\"c\",\"players\":[\"1\",\"2\"]}}";
            User user = new User(json);
            Console.WriteLine("Name : " + user.name);
            Console.WriteLine("Teamname : " + user.teamname);
            Console.WriteLine("Email : " + user.email);
            Console.WriteLine("Players:");
            foreach (var player in user.players)
                Console.WriteLine(player);
        }
    }

    public class User {
        public User(string json) {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            var jsonObject = serializer.Deserialize<dynamic>(json);
            name = (string)jsonObject["user"]["name"];
            teamname = (string)jsonObject["user"]["teamname"];
            email = (string)jsonObject["user"]["email"];
            players = jsonObject["user"]["players"];
        }

        public string name { get; set; }
        public string teamname { get; set; }
        public string email { get; set; }
        public Array players { get; set; }
    }
}

Example 2: using System.Web.Helpers

using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Web.Helpers;

namespace Tests
{
    [TestClass]
    public class JsonTests
    {
        [TestMethod]
        public void TestJsonDecode()
        {
            var json = "{\"user\":{\"name\":\"asdf\",\"teamname\":\"b\",\"email\":\"c\",\"players\":[\"1\",\"2\"]}}";
            dynamic jsonObject = Json.Decode(json);

            dynamic x = jsonObject.user; // result is dynamic json object user with fields name, teamname, email and players with their values
            x = jsonObject.user.name; // result is asdf
            x = jsonObject.user.players; // result is dynamic json array players with its values
        }
    }
}

Usage: JSON object to Custom C# object

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Web.Helpers;
using System.Linq;

namespace Tests
{
    [TestClass]
    public class JsonTests
    {
        [TestMethod]
        public void TestJsonDecode()
        {
            var json = "{\"user\":{\"name\":\"asdf\",\"teamname\":\"b\",\"email\":\"c\",\"players\":[\"1\",\"2\"]}}";
            User user = new User(json);
            Console.WriteLine("Name : " + user.name);
            Console.WriteLine("Teamname : " + user.teamname);
            Console.WriteLine("Email : " + user.email);
            Console.WriteLine("Players:");
            foreach (var player in user.players)
                Console.WriteLine(player);
        }
    }

    public class User {
        public User(string json) {
            var jsonObject = Json.Decode(json);
            name = (string)jsonObject.user.name;
            teamname = (string)jsonObject.user.teamname;
            email = (string)jsonObject.user.email;
            players = (DynamicJsonArray) jsonObject.user.players;
        }

        public string name { get; set; }
        public string teamname { get; set; }
        public string email { get; set; }
        public Array players { get; set; }
    }
}

This code requires adding System.Web.Helpers namespace found in,

%ProgramFiles%\Microsoft ASP.NET\ASP.NET Web Pages{VERSION}\Assemblies\System.Web.Helpers.dll

Or

%ProgramFiles(x86)%\Microsoft ASP.NET\ASP.NET Web Pages{VERSION}\Assemblies\System.Web.Helpers.dll

Hope this helps!
