JSON, Java Script Object Notation, a light weight object representation.
We can convert JSON string to C# object by using the following web site http://json2csharp.com/#
{ "firstName":"John", "lastName":"Doe", "dateOfBirth": { "year":"2000", "month":"12", "day":"20" } }
This JSON string can be represented by C# class in the following way.
public class DateOfBirth { public string year { get; set; } public string month { get; set; } public string day { get; set; } } public class RootObject { public string firstName { get; set; } public string lastName { get; set; } public DateOfBirth dateOfBirth { get; set; } }
Final code can be shown for Console application in the following way.
using System.Web.Script.Serialization; namespace Obj_4_4_Serialize_Deserialize_Data { //LISTING 4-79 Using the DataContractJsonSerializer public class DateOfBirth { public string year { get; set; } public string month { get; set; } public string day { get; set; } } public class RootObject { public string firstName { get; set; } public string lastName { get; set; } public DateOfBirth dateOfBirth { get; set; } } class Program { static void Main(string[] args) { System.Console.WriteLine("JavaScript Deserialize:"); string str = @"{""firstName"":""Mahbub"",""lastName"":""Rahman"",""dateOfBirth"":{""year"":""1901"",""month"":""4"",""day"":""30""}}"; RootObject classForm = new JavaScriptSerializer().Deserialize(str); System.Console.WriteLine("FirstName = {0} LastName = {1}", classForm.firstName, classForm.lastName); System.Console.WriteLine("Date of Birth = {0}/{1}/{2}", classForm.dateOfBirth.day, classForm.dateOfBirth.month, classForm.dateOfBirth.year); System.Console.WriteLine("JavaScript Serialize:"); RootObject root = new RootObject() { firstName = "John", lastName = "Doe", dateOfBirth = new DateOfBirth() { day = "20", month = "12", year = "2000" } }; string jsonstring = new JavaScriptSerializer().Serialize(root); System.Console.WriteLine(jsonstring); } } }
