One popular method for this data exchange is using JSON (JavaScript Object Notation). In this guide, we’ll walk through the process of deserializing a JSON array into C- objects, specifically focusing on how to work with a structure representing human body joint coordinates. The Problem: Understanding the JSON Structure For a project involving the detection of 3D coordinates of human body joints (bones), you may find yourself passing JSON data between languages like Python and C-. The given structure consists of two classes, Bone and Body. Here's the essential structure: [[See Video to Reveal this Text or Code Snippet]] The relevant JSON format contains an array of objects, where each object represents an instance of Bone. Example JSON Data [[See Video to Reveal this Text or Code Snippet]] The Solution: How to Deserialize JSON in C- To read this coordinate data in C-, we will use the popular library Newtonsoft.Json. Below, we’ll discuss the adjustments you need to make to your code to correctly deserialize and print this data. Step 1: Adjust the Bone Class We need to ensure that your Bone class can handle the data types correctly. Instead of using int for the coordinates, we should use double since the JSON provides floating-point numbers. [[See Video to Reveal this Text or Code Snippet]] Step 2: Deserialize the JSON Array Since your JSON data is an array of Bone objects, you should deserialize it as a collection of Bone. Here’s how you can do that: [[See Video to Reveal this Text or Code Snippet]] Summary of Key Steps: Adjust Data Types: Ensure that your coord array within Bone uses double instead of int. Deserialize Correctly: Use List<Bone> when deserializing the JSON to align with the structure of your JSON data, which represents an array of bones, not a single body object. Conclusion Deserializing a JSON array into C- objects can be straightforward with the right approach. By ensuring that your class definitions match your JSON structure and utilizing the power of Newtonsoft.Json, you can seamlessly transition from JSON to C- objects. Feel free to use the provided example code in your projects, and modify it according to your needs. Happy coding!
