DateTime Format change after JSON parsing in c# [duplicate]

There are multiple methods to extract the date from the DateTime variable.

First: You can use the [DataType(DataType.Date)] annotation above the DateTime property in your model.

Second: You can use ToString() method to capture the date from the DateTime variable.

The code snippet for the second method is below.

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;

namespace ExportDTtoJSON
{
    class Program
    {
        static void Main(string[] args)
        {
            List<Person> p = new List<Person>();
            p.Add(new Person
            {
                FirstName = "Ahmad",
                DOB = new DateTime(2021, 1, 1).ToString("yyyy/mm/dd")
            });
            p.Add(new Person
            {
                FirstName = "Khan",
                DOB = new DateTime(2022, 3, 4).ToString("yyyy/mm/dd")
             });

            var jsonObject = Newtonsoft.Json.JsonConvert.SerializeObject(p);
        }
    }

    public class Person
    {
        public string FirstName { get; set; }
        public string DOB { get; set; }
    }
}

jsonObject has the JSON data, and you can apply your logic to that.
