How to convert JSON String to Object in C#?

Question

Ravi Vishwakarma · Answer

In C#, you can convert a JSON string to an object using the System.Text.Json or
Newtonsoft.Json (JSON.NET) libraries.and 
Both libraries provide methods to deserialize JSON into C# objects.
Here's how you can do it using both libraries:
Using ‘System.Text.Json’
using System;
using System.Text.Json;
class Program
{
   static void Main()
   {
       // JSON string
       string json = "{\"Name\":\"John\",\"Age\":30,\"IsStudent\":true}";
       // Deserialize the JSON string to an object
       var obj = JsonSerializer.Deserializeandlt;MyClass>(json);
       // Access object properties
       Console.WriteLine($"Name: {obj.Name}");
       Console.WriteLine($"Age: {obj.Age}");
       Console.WriteLine($"IsStudent: {obj.IsStudent}");
   }
   // Define a class to match the structure of the JSON object
   public class MyClass
   {
       public string Name { get; set; }
       public int Age { get; set; }
       public bool IsStudent { get; set; }
   }
}
Using ‘Newtonsoft.Json’
using System;
using Newtonsoft.Json;
using System;
using Newtonsoft.Json;
namespace ConsoleApplication1
{
   public class JSONToObject
   {
       public static void Convert()
       {
           // JSON string
           string json = "{\"Name\":\"John\",\"Age\":30,\"IsStudent\":true}";
           // Deserialize the JSON string to an object
           var obj = JsonConvert.DeserializeObjectandlt;MyClass>(json);
           // Access object properties
           Console.WriteLine("Name: {0}", obj.Name);
           Console.WriteLine("Age: {0}", obj.Age);
           Console.WriteLine("IsStudent: {0}", obj.IsStudent);
       }
   }
   // Define a class to match the structure of the JSON object
   public class MyClass
   {
       public string Name { get; set; }
       public int Age { get; set; }
       public bool IsStudent { get; set; }
   }
}
Explanation
In both examples, a JSON string is provided, representing an object with properties Name, Age, and IsStudent.The JsonSerializer.Deserializeandlt;T> method (from System.Text.Json) or
JsonConvert.DeserializeObjectandlt;T> method (from Newtonsoft.Json) is used to convert the
JSON string into an instance of a specific C# class (MyClass in this case).The resulting object (obj) can then be used to access its properties as usual.
Library Selection
System.Text.Json is part of the .NET Core and .NET 5+ frameworks, providing high-performance JSON parsing and serialization.Newtonsoft.Json (JSON.NET) is a popular third-party library with extensive features and flexibility. It has been widely used in the .NET ecosystem for many years and provides excellent support for various scenarios.
