Summary
In this module, you learned about JavaScript Object Notation (JSON), a lightweight, text-based data interchange format that is easy for humans and machines to read and write. The module covered the syntax of JSON, its basic data types, and JSON's use in storing and exchanging data across various applications. You learned about the C# programming language's built-in support for working with JSON data through the System.Text.Json namespace, including classes and methods for serializing and deserializing JSON data.
The main takeaways from this module include understanding the process of converting C# objects to JSON and vice versa, known as serialization and deserialization. You learned about the JsonSerializer.Serialize method in C#, which converts objects into JSON strings for easy storage or transmission. You also learned about the JsonSerializer.Deserialize method, which converts a JSON string back into an object. The module also covered the JsonSerializerOptions class and Data Transfer Objects (DTOs), essential tools for managing the serialization and deserialization of complex objects.
