In this example is Bill object that hold billing data about Car object.

Serialize Object to String

Below is example code to serialize object to json string. At line 39 is code to convert object into json string with beautiful json format.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

using Newtonsoft.Json; using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Text; namespace JSON { class JSonExample { static void Main(string[] args) { List<Car> cars = new List<Car>(); float totalPrice = 0; Car car1 = new Car(); car1.brand = "Honda"; car1.color = "Bronze"; car1.price = 100; car1.id = 1; totalPrice = totalPrice + car1.price; Car car2 = new Car(); car2.brand = "Toyota"; car2.color = "Red"; car2.price = 90; car2.id = 1; totalPrice = totalPrice + car2.price; cars.Add(car1); cars.Add(car2); Bill bill = new Bill(); bill.billNo = "ABC123"; bill.cars = cars; bill.totalPrice = totalPrice; bill.address = new string[] { "Address1", "Address2"}; string json = JsonConvert.SerializeObject(bill, Formatting.Indented); Console.WriteLine(json); // Press any key to close window Console.ReadLine(); } } }

Output
