Easy Way To Convert JSON Into C# Class

Introduction

In this blog, we are going to learn how to convert a JSON object into C# class.

Conversion

For this example, we are using a fake RESTFul service. This fake RESTFul service is using JSON and will convert it to C# class. To use a fake RESTFul Service, search for “JsonPlaceholder” and open the first link.

Link - https://jsonplaceholder.typicode.com/

Now, we have to find the end points.

Scroll down on the JsonPlaceholder page and you will find the resources.
C#
These are all the end points. You can use them in your application. In this example, we are going to use /Posts end point. So, click on the link and you will see JSON result. Then, copy the link of end point.

After hitting the /Post end point, you can see the results shown below. This is a JSON object and we will convert this in C# class.

  1. [{  
  2.         "userId": 1,  
  3.         "id": 1,  
  4.         "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",  
  5.         "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto"  
  6.     }, {  
  7.         "userId": 1,  
  8.         "id": 2,  
  9.         "title": "qui est esse",  
  10.         "body": "est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla"  
  11.     }, {  
  12.         "userId": 1,  
  13.         "id": 3,  
  14.         "title": "ea molestias quasi exercitationem repellat qui ipsa sit aut",  
  15.         "body": "et iusto sed quo iure\nvoluptatem occaecati omnis eligendi aut ad\nvoluptatem doloribus vel accusantium quis pariatur\nmolestiae porro eius odio et labore et velit aut"  
  16.     }, {  
  17.         "userId": 1,  
  18.         "id": 4,  
  19.         "title": "eum et est occaecati",  
  20.         "body": "ullam et saepe reiciendis voluptatem adipisci\nsit amet autem assumenda provident rerum culpa\nquis hic commodi nesciunt rem tenetur doloremque ipsam iure\nquis sunt voluptatem rerum illo velit"  
  21.     }, {  
  22.         "userId": 1,  
  23.         "id": 5,  
  24.         "title": "nesciunt quas odio",  
  25.         "body": "repudiandae veniam quaerat sunt sed\nalias aut fugiat sit autem sed est\nvoluptatem omnis possimus esse voluptatibus quis\nest aut tenetur dolor neque"  
  26.     },  

So, we are going to use “Json2csharp”. Open this link and paste your end point here. You will see that this will automatically generate C# class from JSON.

C#

Result
  1. public class RootObject
  2. {
  3. public int userId { get; set; }
  4. public int id { get; set; }
  5. public string title { get; set; }
  6. public string body { get; set; }
  7. }

So, here you will see that the C# class is automatically generated by the JSON present in the URL.

You can also write JSON to convert it into C# class. Or you can paste the URL which contains JSON. Then, click "Convert" to generate C# class.
