How to convert .NET object to JSON string • 2. How to convert a JSON string to .NET object • We will be using the following Employee class • public class Employee • { • public string firstName { get; set; } • public string lastName { get; set; } • public string gender { get; set; } • public int salary { get; set; } • } • Replace lt; with LESSTHAN symbol and gt; with GREATERTHAN symbol • The following example converts List lt;Employee gt; objects to a JSON string. Serialize() method of JavaScriptSerializer class converts a .NET object to a JSON string. JavaScriptSerializer class is present in System.Web.Script.Serialization namespace. • using System; • using System.Collections.Generic; • using System.Web.Script.Serialization; • namespace Demo • { • public partial class WebForm1 : System.Web.UI.Page • { • protected void Page_Load(object sender, EventArgs e) • { • Employee employee1 = new Employee • { • firstName = Todd , • lastName = Grover , • gender = Male , • salary = 50000 • }; • Employee employee2 = new Employee • { • firstName = Sara , • lastName = Baker , • gender = Female , • salary = 40000 • }; • List lt;Employee gt; listEmployee = new List lt;Employee gt;(); • listEmployee.Add(employee1); • listEmployee.Add(employee2); • JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer(); • string JSONString = javaScriptSerializer.Serialize(listEmployee); • Response.Write(JSONString); • } • } • } • Output : • [{ firstName : Todd , lastName : Grover , gender : Male , salary :50000},{ firstName : Sara , lastName : Baker , gender : Female , salary :40000}] • The following example converts a JSON string to List lt;Employee gt; objects. Deserialize() method of JavaScriptSerializer class converts a JSON string to List lt;Employee gt; objects. • string jsonString = [{\\ firstName\\ :\\ Todd\\ ,\\ lastName\\ :\\ Grover\\ ,\\ gender\\ :\\ Male\\ ,\\ salary\\ :50000},{\\ firstName\\ :\\ Sara\\ ,\\ lastName\\ :\\ Baker\\ ,\\ gender\\ :\\ Female\\ ,\\ salary\\ :40000}] ; • JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer(); • List lt;Employee gt; employees = (List lt;Employee gt;)javaScriptSerializer.Deserialize(jsonString, typeof(List lt;Employee gt;)); • foreach(Employee employee in employees) • { • Response.Write( First Name = + employee.firstName + lt;br/ gt; ); • Response.Write( Last Name = + employee.lastName + lt;br/ gt; ); • Response.Write( Gender = + employee.gender + lt;br/ gt; ); • Response.Write( Salary = + employee.salary + lt;br/ gt; lt;br/ gt; ); • }
