How to parse JSON using RestSharp?

RestSharp is a popular HTTP client library for .NET that can also be used to parse JSON responses from web APIs. Here's an example of how to parse JSON using RestSharp:

  • Make a request to a web API that returns JSON data. Here's an example of how to do this using RestSharp:
using RestSharp; var client = new RestClient("https://example.com/api"); var request = new RestRequest("users", Method.GET); var response = client.Execute(request); if (response.IsSuccessful) { // JSON data is contained in response.Content }

In this example, we create a RestClient object to connect to the API at https://example.com/api. We then create a RestRequest object to request the users endpoint using the GET method.

We make the request using the client.Execute() method, which returns a IRestResponse object. We check the IsSuccessful property of the response to see if the request was successful.

  • Parse the JSON data in the response using a JSON parsing library like Newtonsoft.Json.
using Newtonsoft.Json; if (response.IsSuccessful) { var users = JsonConvert.DeserializeObject<List<User>>(response.Content); }

In this example, we assume that the JSON data in the response represents a collection of User objects. We use the JsonConvert.DeserializeObject() method from Newtonsoft.Json to deserialize the JSON data into a List<User> object.

Note that you will need to install the Newtonsoft.Json package using NuGet in order to use the JsonConvert class.

  • Use the parsed data in your application.
if (response.IsSuccessful) { var users = JsonConvert.DeserializeObject<List<User>>(response.Content); foreach (var user in users) { Console.WriteLine(user.Name); } }

In this example, we loop through the collection of User objects and output the name of each user to the console.

By using RestSharp and a JSON parsing library like Newtonsoft.Json, you can easily parse JSON responses from web APIs in your .NET applications.
