Converting Object to JSON and JSON to C# Objects

In this blog we will see how we can convert C# objects to JSON and JSON to objects.

JSON is a faster and more lightweight data exchange pattern between servers and the clients.

Let us see in a demo how to convert an object to JSON and JSON Text into a C# object.

Nuget provides a plug-in called JSON.NET which provides the facility to convert this. 

 
Let us say we have a employee class as below:

public class Employee
{
    public int EmployeeID
    {
        get;
        set;
    }
    public string EmployeeName
    {
        get;
        set;
    }
    public string DeptWorking
    {
        get;
        set;
    }
    public int Salary
    {
        get;
        set;
    }
}

And we have a list of employee data; we will convert this into JSON text.

using System;
using System.Collections.Generic;
using Newtonsoft.Json;
namespace JSON
{
    class Program
    {
        static void Main(string[] args)
        {
            List < Employee > lstemployee = new List < Employee > ();
            lstemployee.Add(new Employee()
            {
                EmployeeID = 100, EmployeeName = "Pradeep", DeptWorking = "OnLineBanking", Salary = 10000
            });
            lstemployee.Add(new Employee()
            {
                EmployeeID = 101, EmployeeName = "Mark", DeptWorking = "OnLineBanking", Salary = 20000
            });
            lstemployee.Add(new Employee()
            {
                EmployeeID = 102, EmployeeName = "Smith", DeptWorking = "Mobile banking", Salary = 10000
            });
            lstemployee.Add(new Employee()
            {
                EmployeeID = 103, EmployeeName = "John", DeptWorking = "Testing", Salary = 7000
            });
            string output = JsonConvert.SerializeObject(lstemployee);
            Console.WriteLine(output);
            Console.ReadLine();
            List < Employee > deserializedProduct = JsonConvert.DeserializeObject < List < Employee >> (output);
        }
    }
}

Output 

 We saw how we converted an object to JSON and JSON to objects. Thanks for reading.
