Description:

Provides high-performance and low-allocating types that serialize objects to JavaScript Object Notation (JSON) text and deserialize JSON text to objects, with UTF-8 support built-in. Also provides types to read and write JSON text encoded as UTF-8, and to create an in-memory document object model (DOM), that is read-only, for random access of the JSON elements within a structured view of the data.

Commonly Used Types:

System.Text.Json.JsonSerializer

System.Text.Json.JsonDocument

System.Text.Json.JsonElement

System.Text.Json.Utf8JsonWriter

System.Text.Json.Utf8JsonReader

Create a Model class named Class1.cs

using System;

namespace MvcSerialization.Models

{

    public class Class1

    {

        public string ProductName { get; set; }

        public DateTimeOffset MfgDate { get; set; }

        public int Price { get; set; }

        public string Description { get; set; }

    }

}

In the HomeController.cs, write the following code.

using MvcSerialization.Models;

using System;

using System.Text.Json;

using System.Web.Mvc;

namespace MvcSerialization.Controllers

{

    public class HomeController : Controller

    {

        // GET: Home

        public string Index()

        {

            Class1 obj = new Class1();

            obj.ProductName = "Paracetamol";

            obj.MfgDate = DateTime.Now;

            obj.Price = 12;

            obj.Description = "This drug is used to treat mild to moderate pain from headaches, menstrual periods, toothaches, backaches, osteoarthritis, or flu aches and pains.";

            string jsonString = JsonSerializer.Serialize(obj);

            return jsonString;

        }

    }

}

{"ProductName":"Paracetamol","MfgDate":"2021-04-29T17:26:47.3562527+05:30","Price":12,"Description":"This drug is used to treat mild to moderate pain from headaches, menstrual periods, toothaches, backaches, osteoarthritis, or flu aches and pains."}
