You can use the C# dynamic type to make things easier. This technique also makes re-factoring simpler as it does not rely on magic-strings.
JSON
The JSON string below is a simple response from an HTTP API call, and it defines two properties: Id and Name.
{"Id": 1, "Name": "biofractal"}
C#
Use JsonConvert.DeserializeObject<dynamic>() to deserialize this string into a dynamic type then simply access its properties in the usual way.
dynamic results = JsonConvert.DeserializeObject<dynamic>(json);
var id = results.Id;
var name= results.Name;
If you specify the type of the results variable as dynamic, instead of using the var keyword, then the property values will correctly deserialize, e.g. Id to an int and not a JValue (thanks to GFoley83 for the comment below).
Note: The NuGet link for the Newtonsoft assembly is http://nuget.org/packages/newtonsoft.json.
Package: You can also add the package with nuget live installer, with your project opened just do browse package and then just install it install, unistall, update, it will just be added to your project under Dependencies/NuGet

Newtonsoft.Json accepts non-string values, such as a number or the literals true and false, for deserialization to properties of type string. Here's an example of JSON that Newtonsoft.Json successfully deserializes to the following class:

Similar to serialization, JsonConvert provides various options to customize the deserialization process. You can use attributes, custom converters, and specify error handling during deserialization. Here’s an example that demonstrates some of these features: using Newtonsoft.Json; using Newtonsoft.Json.Converters; using System; public class Person { [JsonProperty("full_name")] public string Name { get; set; } public int Age { get; set; } [JsonConverter(typeof(StringEnumConverter))] public Gender Gender { get; set; } } public enum Gender { Male, Female } public class Program { public static v

Comprehensive Guide to Using JSON and Newtonsoft.Json in .NET | by İbrahim Emre POLAT | Medium
June 14, 2024 - Newtonsoft.Json makes it simple to deserialize JSON strings into .NET objects. Let’s explore how to deserialize JSON into objects using Newtonsoft.Json. To deserialize JSON into a C# object, you can use the JsonConvert.DeserializeObject<T> method. Here's a basic example:

If you just need to get a few items from the JSON object, I would use Json.NET's LINQ to JSON JObject class. For example:
JToken token = JObject.Parse(stringFullOfJson);
int page = (int)token.SelectToken("page");
int totalPages = (int)token.SelectToken("total_pages");
I like this approach because you don't need to fully deserialize the JSON object. This comes in handy with APIs that can sometimes surprise you with missing object properties, like Twitter.

C# Json.NET - working with JSON with Newtonsoft Json.NET
In this article we work with Newtonsoft Json.NET library. In the standard library, we can alternatively use System.Text.Json. JsonConvert provides methods for converting between .NET types and JSON types. JsonConvert.SerializeObject serializes the specified object to a JSON string. JsonConvert.DeserializeObject deserializes the JSON to a .NET object. In the following example, we serialize an object to a JSON string.

They are located in the Newtonsoft.Json.Linq namespace. These objects allow you to use LINQ to JSON objects with objects that read and write JSON, such as the JsonSerializer. For example you can deserialize from a LINQ to JSON object into a regular .NET object and vice versa.

Serialization Guide
In Json.NET, dynamic properties are serialized and deserialized exactly the same as untyped objects: because dynamic isn't an actual type, Json.NET falls back to deserializing the JSON as LINQ to JSON objects. The second usage of dynamic in .NET are by the types that implement IDynamicMetaObjectProvider. This interface lets the implementer create dynamic objects that intercept the property and method calls on an object and use them. ExpandoObject is a good example of a dynamic object.
