Selenium with C# Cheat Sheet

Driver Initialization

Locating Elements

Working with Files

using OpenQA.Selenium;

IWebElement fileInput = driver.FindElement(By.Id("file-upload"));
fileInput.SendKeys(@"path\to\your\file.txt");
driver.FindElement(By.Id("file-submit")).Submit();

using System.IO;

string[] lines = File.ReadAllLines(@"path\to\your\file.txt");

foreach (string line in lines)
{
   Console.WriteLine(line);
}

using System.IO;
using CsvHelper;

using (var reader = new StreamReader(@"path\to\your\csvfile.csv"))
using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
{
  var records = csv.GetRecords<dynamic>().ToList();
}

using OfficeOpenXml;
using System.IO;

FileInfo file = new FileInfo(@"path\to\your\excelfile.xlsx");

using (ExcelPackage package = new ExcelPackage(file))
{
  ExcelWorksheet worksheet = package.Workbook.Worksheets["Sheet1"];
  int rowCount = worksheet.Dimension.Rows;
  int colCount = worksheet.Dimension.Columns;

  for (int row= 1; row <= rowCount; row++) { 
    for (int col = 1; col <= colCount; col++) { 

      Console.Write(worksheet.Cells[row, col].Value.ToString() + "\t"); 

    } 
		
    Console.WriteLine(); 
  } 
}

Selenium Navigators

Working with Windows

string mainWindowHandle = driver.CurrentWindowHandle;

ReadOnlyCollection<string> allWindowHandles = driver.WindowHandles;

string windowHandle = driver.CurrentWindowHandle; 
driver.SwitchTo().Window(windowHandle);

driver.Close();

Working with Frames

driver.SwitchTo().Frame("frameName");

driver.SwitchTo().Frame(1);

IWebElement iframe = driver.FindElement(By.CssSelector("#modal>iframe")); 
driver.SwitchTo().Frame(iframe);

driver.SwitchTo().DefaultContent();

Working with Dropdowns (Select Elements)

var dropdown = driver.FindElement(By.Id("dropdown_id"));

var select = new SelectElement(dropdown);

select.SelectByText("Option Text");

select.SelectByValue("option_value");

select.SelectByIndex(1);

select.DeselectAll();

var selectedOptions = select.AllSelectedOptions;

var firstSelectedOption = select.SelectedOption;

Mouse Actions

var actions = new Actions(driver); 
actions.Click(element).Perform();

actions.DoubleClick(element).Perform();

actions.ContextClick(element).Perform();

actions.DragAndDrop(sourceElement, targetElement).Perform();

actions.MoveToElement(element).Perform();

Working with Alerts

IAlert alert = driver.SwitchTo().Alert();

alert.SendKeys("Selenium");

driver.SwitchTo().Alert().Dismiss();

string alertText = alert.Text;

Selenium Operations

driver.Navigate().GoToUrl("<URL>");

var buttonElement = driver.FindElement(By.CssSelector("<button_element_css_selector>")); 
buttonElement.Click();

var title = driver.Title; 
Console.WriteLine(title);

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); 
var element = wait.Until(ExpectedConditions.ElementIsVisible(By.Id("<element ID>")));

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); 
var element = wait.Until(ExpectedConditions.ElementToBeClickable(By.Id("<element ID>")));

driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10); // 10 seconds

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); 
var element = wait.Until(ExpectedConditions.ElementLocated(By.CssSelector(“<element_css_selector>”))); // 10 seconds

Thread.Sleep(5000); // 5 seconds or 5000 milliseconds

var screenshot = ((ITakesScreenshot)driver).GetScreenshot();
screenshot.SaveAsFile("screenshot.png", ScreenshotImageFormat.Png);

var inputElement = driver.FindElement(By.CssSelector("<input_element_css_selector>")); 
inputElement.Clear();

((IJavaScriptExecutor)driver).ExecuteScript(“document.querySelector(‘<element_css_selector>’).setAttribute(‘disabled’, ”);”);

((IJavaScriptExecutor)driver).ExecuteScript("document.querySelector('<element_css_selector>').removeAttribute('disabled');");
