Actualizado:

RestSharp is a popular open-source .NET library for making HTTP requests in C#. It simplifies the process of working with RESTful APIs, providing a straightforward and flexible way to communicate with web services. In this article, we'll explore the crucial features of RestSharp and IronPDF and demonstrate how you can extract data and generate a PDF.

Why RestSharp?

In modern, multi-tier applications, different services need to communicate with each other very often, and RestSharp offers a simple and efficient way by encapsulating all the complexities. This simplifies the software development process greatly.

Install RestSharp

RestSharp is available as a NuGet package and can be installed in your C# project. You can do this using the NuGet Package Manager Console or the Visual Studio NuGet Package Manager UI.

Install-Package RestSharp

Making Simple GET Requests

Let's start with a simple example of making a GET request to a RESTful API using RestSharp. Suppose we want to retrieve information from a public ASP.NET core API that returns user data:

using RestSharp;
namespace rest_sharp_demo
{
    class Program
    {
        static void Main()
        {
            // Base URL for the REST API
            var baseUrl = "https://jsonplaceholder.typicode.com/users";

            // Create a RestClientOptions with default credentials
            var options = new RestClientOptions(baseUrl) { UseDefaultCredentials = true };
            var client = new RestClient(options);

            // Create a RestRequest for the GET method
            var request = new RestRequest();

            // Execute the request and get the response
            var response = client.Get(request);

            // Check if the request was successful
            if (response.IsSuccessful)
            {
                // Output the response body content
                Console.WriteLine(response.Content);
            }
            else
            {
                // Handle the error
                Console.WriteLine($"Error: {response.ErrorMessage}");
            }
        }

        // Additional method to log data
        public void LogData(string msg)
        {
            Console.WriteLine(msg);
        }
    }
}
using RestSharp;
namespace rest_sharp_demo
{
    class Program
    {
        static void Main()
        {
            // Base URL for the REST API
            var baseUrl = "https://jsonplaceholder.typicode.com/users";

            // Create a RestClientOptions with default credentials
            var options = new RestClientOptions(baseUrl) { UseDefaultCredentials = true };
            var client = new RestClient(options);

            // Create a RestRequest for the GET method
            var request = new RestRequest();

            // Execute the request and get the response
            var response = client.Get(request);

            // Check if the request was successful
            if (response.IsSuccessful)
            {
                // Output the response body content
                Console.WriteLine(response.Content);
            }
            else
            {
                // Handle the error
                Console.WriteLine($"Error: {response.ErrorMessage}");
            }
        }

        // Additional method to log data
        public void LogData(string msg)
        {
            Console.WriteLine(msg);
        }
    }
}
Imports RestSharp

RestSharp also supports asynchronous requests and responses using the async API methods.

Handling Response Data

RestSharp provides convenient methods for deserializing response content into C# objects. Let's extend our example to deserialize the JSON response data into a list of user objects:

// Deserialize JSON response into a list of User objects
var users = JsonSerializer.Deserialize<List<User>>(response.Content);

// Output user information
foreach (var user in users)
{
    Console.WriteLine($"User ID: {user.Id}, Name: {user.Name}, Email: {user.Email}");
}
// Deserialize JSON response into a list of User objects
var users = JsonSerializer.Deserialize<List<User>>(response.Content);

// Output user information
foreach (var user in users)
{
    Console.WriteLine($"User ID: {user.Id}, Name: {user.Name}, Email: {user.Email}");
}
' Deserialize JSON response into a list of User objects
Dim users = JsonSerializer.Deserialize(Of List(Of User))(response.Content)

' Output user information
For Each user In users
	Console.WriteLine($"User ID: {user.Id}, Name: {user.Name}, Email: {user.Email}")
Next user
$vbLabelText   $csharpLabel

In this example, we have defined a User class with properties corresponding to the JSON fields. We have used JsonSerializer.Deserialize from the System.Text.Json namespace.

public class User
{
    [JsonPropertyName("company")]
    public Company Company { get; set; }

    [JsonPropertyName("id")]
    public int Id { get; set; }

    [JsonPropertyName("phone")]
    public string Phone { get; set; }

    [JsonPropertyName("website")]
    public string Website { get; set; }

    [JsonPropertyName("name")]
    public string Name { get; set; }

    [JsonPropertyName("username")]
    public string Username { get; set; }

    [JsonPropertyName("email")]
    public string Email { get; set; }

    [JsonPropertyName("address")]
    public Address Address { get; set; }
}
public class User
{
    [JsonPropertyName("company")]
    public Company Company { get; set; }

    [JsonPropertyName("id")]
    public int Id { get; set; }

    [JsonPropertyName("phone")]
    public string Phone { get; set; }

    [JsonPropertyName("website")]
    public string Website { get; set; }

    [JsonPropertyName("name")]
    public string Name { get; set; }

    [JsonPropertyName("username")]
    public string Username { get; set; }

    [JsonPropertyName("email")]
    public string Email { get; set; }

    [JsonPropertyName("address")]
    public Address Address { get; set; }
}
Public Class User
	<JsonPropertyName("company")>
	Public Property Company() As Company

	<JsonPropertyName("id")>
	Public Property Id() As Integer

	<JsonPropertyName("phone")>
	Public Property Phone() As String

	<JsonPropertyName("website")>
	Public Property Website() As String

	<JsonPropertyName("name")>
	Public Property Name() As String

	<JsonPropertyName("username")>
	Public Property Username() As String

	<JsonPropertyName("email")>
	Public Property Email() As String

	<JsonPropertyName("address")>
	Public Property Address() As Address
End Class

Output

All the user IDs and names are displayed in the output.

RestSharp C# (How It Works For Developer): Figure 1 - Console Output displaying all the User IDs and Names.

The entire code is available in Git at this link.

Content Type

RestSharp supports sending XML or JSON body requests. The AddJsonBody or AddXmlBody methods of the RestRequest instance can be used to add JSON or XML body. RestSharp will set the content type automatically. It handles JSON or XML responses automatically.

// Serialize the user object to JSON
var jsonBodyString = JsonSerializer.Serialize(newUser);

// Create a RestRequest for the POST method with the JSON request data
var requestData = new RestRequest().AddJsonBody(jsonBodyString);
var response = client.ExecutePost(requestData);
// Serialize the user object to JSON
var jsonBodyString = JsonSerializer.Serialize(newUser);

// Create a RestRequest for the POST method with the JSON request data
var requestData = new RestRequest().AddJsonBody(jsonBodyString);
var response = client.ExecutePost(requestData);
' Serialize the user object to JSON
Dim jsonBodyString = JsonSerializer.Serialize(newUser)

' Create a RestRequest for the POST method with the JSON request data
Dim requestData = (New RestRequest()).AddJsonBody(jsonBodyString)
Dim response = client.ExecutePost(requestData)
$vbLabelText   $csharpLabel

Sending Data with POST Requests

RestSharp also supports sending data in the request body, which is common when creating or updating resources. Let's modify our example to demonstrate a POST request API:

using RestSharp;
using System.Text.Json;

namespace rest_sharp_demo
{
    class Program
    {
        static void Main()
        {
            var client = new RestClient("https://jsonplaceholder.typicode.com/users");

            // New user object
            var newUser = new User
            {
                Name = "John Doe",
                Email = "john.doe@example.com"
            };

            // Serialize the user object to JSON
            var jsonBody = JsonSerializer.Serialize(newUser);

            // Create a RestRequest for the POST method with the JSON request body
            var request = new RestRequest().AddJsonBody(jsonBody);

            // Execute the POST request
            var response = client.ExecutePost(request);

            // Check if the request was successful
            if (response.IsSuccessful)
            {
                // Output the response content
                Console.WriteLine(response.Content);
            }
            else
            {
                Console.WriteLine($"Error: {response.ErrorMessage}");
            }
        }
    }
}
using RestSharp;
using System.Text.Json;

namespace rest_sharp_demo
{
    class Program
    {
        static void Main()
        {
            var client = new RestClient("https://jsonplaceholder.typicode.com/users");

            // New user object
            var newUser = new User
            {
                Name = "John Doe",
                Email = "john.doe@example.com"
            };

            // Serialize the user object to JSON
            var jsonBody = JsonSerializer.Serialize(newUser);

            // Create a RestRequest for the POST method with the JSON request body
            var request = new RestRequest().AddJsonBody(jsonBody);

            // Execute the POST request
            var response = client.ExecutePost(request);

            // Check if the request was successful
            if (response.IsSuccessful)
            {
                // Output the response content
                Console.WriteLine(response.Content);
            }
            else
            {
                Console.WriteLine($"Error: {response.ErrorMessage}");
            }
        }
    }
}
Imports RestSharp
Imports System.Text.Json

Namespace rest_sharp_demo
	Friend Class Program
		Shared Sub Main()
			Dim client = New RestClient("https://jsonplaceholder.typicode.com/users")

			' New user object
			Dim newUser = New User With {
				.Name = "John Doe",
				.Email = "john.doe@example.com"
			}

			' Serialize the user object to JSON
			Dim jsonBody = JsonSerializer.Serialize(newUser)

			' Create a RestRequest for the POST method with the JSON request body
			Dim request = (New RestRequest()).AddJsonBody(jsonBody)

			' Execute the POST request
			Dim response = client.ExecutePost(request)

			' Check if the request was successful
			If response.IsSuccessful Then
				' Output the response content
				Console.WriteLine(response.Content)
			Else
				Console.WriteLine($"Error: {response.ErrorMessage}")
			End If
		End Sub
	End Class
End Namespace
$vbLabelText   $csharpLabel

In this example, we create a new User object, serialize it to JSON, and include it in the request body using the AddJsonBody method. The server receives the JSON data and processes the request accordingly.

Authentication

RestSharp also supports sending requests with authentication. The RestClientOptions can include authentication parameters.

var options = new RestClientOptions("https://auth.net")
{
    Authenticator = new HttpBasicAuthenticator(_clientId, _clientSecret)
};
var options = new RestClientOptions("https://auth.net")
{
    Authenticator = new HttpBasicAuthenticator(_clientId, _clientSecret)
};
Dim options = New RestClientOptions("https://auth.net") With {.Authenticator = New HttpBasicAuthenticator(_clientId, _clientSecret)}
$vbLabelText   $csharpLabel

Here we are using basic client ID secret authentication, which is sent in every request.

Error Handling

RestSharp can handle errors that occur during URL requests, such as timeout, authentication, or authorization errors. RestSharp doesn't throw an exception if the request fails automatically. It needs to be configured manually.

The following error handling configurations can be done:

  • FailOnDeserializationError: Setting this property to true will tell RestSharp to consider failed deserialization as an error and set the ResponseStatus to Error accordingly.
  • ThrowOnDeserializationError: Setting this property to true will tell RestSharp to throw when deserialization fails.
  • ThrowOnAnyError: Throws an exception if any errors occur when making a request or during deserialization.
var restClientOptions = new RestClientOptions(url)
{
    ThrowOnAnyError = true
};
var client = new RestClient(restClientOptions);
var restClientOptions = new RestClientOptions(url)
{
    ThrowOnAnyError = true
};
var client = new RestClient(restClientOptions);
Dim restClientOptions As New RestClientOptions(url) With {.ThrowOnAnyError = True}
Dim client = New RestClient(restClientOptions)

Introducing IronPDF

IronPDF is a C# PDF library from Iron Software that helps to read and generate PDF documents. It can convert easily formatted documents with style information to PDF. IronPDF can easily generate PDFs from HTML content; it can download the HTML from a URL and then generate PDFs.

A key feature of IronPDF is HTML to PDF conversion, preserving all your layouts and styles. It turns web content into PDFs, making it ideal for reports, invoices, and documentation. HTML files, URLs, and HTML strings can be easily converted to PDFs.

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Create a PDF renderer using Chrome
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }
}
using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Create a PDF renderer using Chrome
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }

Here we are first generating an HTML string from the users list with all the formatting required for the reports. Then we use IronPDF to generate a PDF document. We use the RenderHtmlAsPdf method to convert the HTML string to a PDF document. The generated document is as below:

RestSharp C# (How It Works For Developer): Figure 4 - Output PDF

The document has a small watermark for trial licenses, which can be removed using a valid license.

Licensing (Free Trial Available)

For the above code to work, a license key is required. This key needs to be placed in appsettings.json as follows:

{
    "IronPdf.LicenseKey": "your license key"
}

A trial license is available for developers upon registering, and no credit card is required for a trial license. One can provide their email ID and register for a free trial.
