Selenium ChromeDriver C# (How it Works For Developers)

In this tutorial, we will dive into the powerful combination of Selenium ChromeDriver and Selenium WebDriver for automating tasks in the Google Chrome browser and IronPDF for converting web content into PDFs. This guide is tailored for beginners, aiming to provide a solid foundation in both technologies.

Selenium ChromeDriver is a key component in web automation, especially for Google Chrome users. It's a standalone server that enables automated control of Chrome version sessions, making it an essential tool for testing and automating web browsers with or without headless mode. With Selenium ChromeDriver, tasks like opening new tabs, navigating to URLs, and interacting with web elements become programmable and repeatable.

IronPDF offers the capability to transform online pages into PDF documents. Whether you're looking to capture the state of a web page for documentation, reporting, or archiving purposes, IronPDF provides a seamless solution. It integrates effortlessly with Selenium, allowing you to convert the automation results into a fixed format.

Setting Up Selenium ChromeDriver

Selenium ChromeDriver is essential for web automation in C#. This section guides you through the installation process and initial configuration, setting the foundation for automated Chrome browser interactions.

Installation Steps

NuGet Package: Install Selenium WebDriver and ChromeDriver through NuGet in Visual Studio. Search for 'Selenium.WebDriver' and 'Selenium.WebDriver.ChromeDriver' and add them to your project.

Matching Chrome Version: Ensure you have the correct and latest ChromeDriver version, which can automatically download the version matching your Chrome browser through NuGet.

Basic Configuration

System Path: After installation, ChromeDriver.exe is located in your project's bin folder. You may need to add this separate executable to your system's path.

Default Settings: In C#, instantiate a new ChromeDriver object which will enable automation. This launches a new Chrome browser instance with default configurations. This instantiation uses the default configuration version of ChromeDriver, which is sufficient for most basic automation tasks.

Example: Launching Chrome

using OpenQA.Selenium.Chrome;
public class ChromeAutomation
{
    public void StartChrome()
    {
        var driver = new ChromeDriver();
        driver.Navigate().GoToUrl("https://www.ironpdf.com");
    }
}

using OpenQA.Selenium.Chrome;
public class ChromeAutomation
{
    public void StartChrome()
    {
        var driver = new ChromeDriver();
        driver.Navigate().GoToUrl("https://www.ironpdf.com");
    }
}

Imports OpenQA.Selenium.Chrome
Public Class ChromeAutomation
	Public Sub StartChrome()
		Dim driver = New ChromeDriver()
		driver.Navigate().GoToUrl("https://www.ironpdf.com")
	End Sub
End Class

This code snippet demonstrates how to launch Chrome using Selenium WebDriver, a fundamental step in web automation.

Basic Automation with ChromeDriver

Once you have set up Selenium ChromeDriver in your C# project, the next step is to automate interactions with web pages. This basic automation will demonstrate how you can use ChromeDriver to navigate, search, and interact with elements on a web page.

Launching and Navigating in Chrome

Opening a URL: Use the Navigate().GoToUrl() method to open web pages.

Interacting with Web Elements: Locate elements using various methods like FindElement() and perform actions like clicking or entering text.

Example: Searching on a Web Page

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
public class WebSearch
{
    public void PerformSearch()
    {
        var driver = new ChromeDriver();
        driver.Navigate().GoToUrl("https://www.google.com");
        var searchBox = driver.FindElement(By.Name("q"));
        searchBox.SendKeys("Selenium ChromeDriver");
        searchBox.Submit();
    }
}

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
public class WebSearch
{
    public void PerformSearch()
    {
        var driver = new ChromeDriver();
        driver.Navigate().GoToUrl("https://www.google.com");
        var searchBox = driver.FindElement(By.Name("q"));
        searchBox.SendKeys("Selenium ChromeDriver");
        searchBox.Submit();
    }
}

Imports OpenQA.Selenium
Imports OpenQA.Selenium.Chrome
Public Class WebSearch
	Public Sub PerformSearch()
		Dim driver = New ChromeDriver()
		driver.Navigate().GoToUrl("https://www.google.com")
		Dim searchBox = driver.FindElement(By.Name("q"))
		searchBox.SendKeys("Selenium ChromeDriver")
		searchBox.Submit()
	End Sub
End Class

In this example, Chrome Driver navigates to Google, finds the search box, enters a query, and submits the search. This demonstrates a simple yet common automation task.

It is the output Google Chrome browser:

Web Page Navigation: Use Selenium ChromeDriver to navigate to and interact with web pages. This could involve filling out forms, navigating through search results, or accessing specific URLs.

Converting Web Content to PDF with IronPDF

Capturing Web Pages as PDFs: After navigating to the desired web content using ChromeDriver, use IronPDF to convert the current web page view into a PDF document.

Example: Web to PDF Conversion

using OpenQA.Selenium.Chrome;
using IronPdf;
public class WebPageToPdf
{
    public void ConvertToPdf(string url)
    {
        var driver = new ChromeDriver();
        driver.Navigate().GoToUrl(url);
        var renderer = new ChromePdfRenderer();;
        var PDF = renderer.RenderUrlAsPdf(url);
        PDF.SaveAs("WebContent.pdf");
        driver.Quit();
    }
}

using OpenQA.Selenium.Chrome;
using IronPdf;
public class WebPageToPdf
