Serializing data/objects using XML is quite a standard way over the Web. But, XML has it’s own set of disadvantages owing to which I tried serializing objects in JSON format. It seems .NET has in-built support for doing the same. One simply needs to use the JavaScriptSerializer class available within ‘System.Web.Script.Serialization’ namespace.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Script.Serialization; /*Add System.Web.Extension library*/

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            JavaScriptSerializer sz = new JavaScriptSerializer();

            List<Employee> empList = new List<Employee>() 
                { new Employee("gaurav", 1), 
                    new Employee("gauz", 2) };

            Console.WriteLine(sz.Serialize(empList));
            Console.ReadLine();
        }
    }

    class Employee
    {
        public string name;
        public int id;

        public Employee() { }

        public Employee(string Name, int ID)
        {
            this.id = ID;
            this.name = Name;
        }
    }
}
