JSON string to object and vice versa

 Simple example (you need .NET 3.5):

The main class is DataContractJsonSerializer

 ...

using System.Runtime.Serialization;

using System.Runtime.Serialization.Json;

namespace JSonExample

{

    [DataContract]

    public class Person

    {

        [DataMember(Name = "Name")]

        public string Name { get; set; }

        [DataMember(Name = "Age")]

        public int Age { get; set; }

    }

   

    class Program

    {

        static void Main(string[] args)

        {

            var customer = new Person {Age = 25, Name = "Albert"};

            string jSon = JSONSerializer<Person>.Serialize(customer);

            //{"Age":25,"Name":"Albert"}

            var deserializedCustomr = JSONSerializer<Person>.DeSerialize(jSon);

        }

    }

    public static class JSONSerializer<T> where T : class

    {

        /// <summary>

        /// Serializes an object to JSON

        /// </summary>

        public static string Serialize(T instance)

        {

            var serializer = new DataContractJsonSerializer(typeof(T));

            using (var stream = new MemoryStream())

            {

                serializer.WriteObject(stream, instance);

                return Encoding.Default.GetString(stream.ToArray());

            }

        }

        /// <summary>

        /// DeSerializes an object from JSON

        /// </summary>

        public static T DeSerialize(string json)

        {

            using (var stream = new MemoryStream(Encoding.Default.GetBytes(json)))

            {

                var serializer = new DataContractJsonSerializer(typeof(T));

                return serializer.ReadObject(stream) as T;

            }

        }

    }

}
