How Can JSON Be Deserialized Into A .net Object Using Newtonsoft (or Possibly LINQ To JSON)?

To deserialize JSON to a .NET object using Newtonsoft.Json (also known as Json.NET) in C#, you can use the JsonConvert.DeserializeObject<T>() method. Here’s an example:

First, make sure to add the Newtonsoft.Json NuGet package to your project.

using Newtonsoft.Json;

// Define your .NET object class
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

// JSON string to deserialize
string json = "{\"Name\":\"John\",\"Age\":30}";

// Deserialize JSON to a Person object
Person person = JsonConvert.DeserializeObject<Person>(json);

// Access deserialized properties
Console.WriteLine("Name: " + person.Name);
Console.WriteLine("Age: " + person.Age);

Output:

Name: John
Age: 30

If you are working with LINQ to JSON, you can also use the JToken.ToObject<T>() method to directly convert a JToken to a .NET object. Here’s an example:

using Newtonsoft.Json.Linq;

// JSON string to deserialize
string json = "{\"Name\":\"John\",\"Age\":30}";

// Parse the JSON string into a JToken
JToken jToken = JToken.Parse(json);

// Convert JToken to a Person object
Person person = jToken.ToObject<Person>();

// Access deserialized properties
Console.WriteLine("Name: " + person.Name);
Console.WriteLine("Age: " + person.Age);

Both methods will achieve the same result. Choose whichever approach suits your needs.
