How to Convert DataTable to JSON in C

In many development scenarios, you may find yourself needing to convert a DataTable into a JSON string. JSON (JavaScript Object Notation) has become a standard for data interchange, especially when working with web services and APIs. In this post, we'll explore different methods to achieve this conversion efficiently in C.

Why Convert DataTable to JSON?

DataTables are pivotal in various backend operations such as database queries and data manipulation. Converting DataTables to JSON is beneficial for:

Interoperability: JSON is widely accepted across different programming environments and platforms.

Integration with APIs: Most modern web APIs utilize JSON, making it essential for front-end and back-end data interchange.

Ease of Parsing: Developers often find it easier to parse JSON compared to other formats like XML.

Using Newtonsoft.Json Library

One of the most popular and straightforward ways to convert a DataTable to JSON in C is by using the Newtonsoft.Json library, also known as Json.NET. Here's a step-by-step guide to perform the conversion.

Step 1: Install Newtonsoft.Json
