It looks like you're encountering an OpenQA.Selenium.WebDriverArgumentException in your Selenium WebDriver code. This error often occurs due to issues with the arguments passed to WebDriver methods or invalid state transitions.

Here are a few things to check and adjust in your code:

  1. URL Format: Ensure the URL you're trying to navigate to includes the protocol (http:// or https://). For example, change "google.com" to "https://www.google.com".

  2. WebDriver Initialization: Make sure that the ChromeDriver is properly initialized and the correct version is used. Compatibility issues between the ChromeDriver and the installed Chrome browser can also cause such errors. Ensure that both are up-to-date and compatible.

  3. Exception Handling: Wrap your code in try-catch blocks to better handle and diagnose exceptions.

  4. Wait for Elements: Make sure the elements you're trying to interact with are fully loaded and visible before interacting with them.

Here's a revised version of your code with these considerations:

static async Task SingleVideo0()
{
    try
    {
        using (IWebDriver driver = new ChromeDriver())
        {
            driver.Navigate().GoToUrl("https://www.google.com");

            WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));

            // Adjust this line according to the actual class name or selector
            var playButtons = wait.Until(_driver => _driver.FindElements(By.ClassName("video-play-button")));

            foreach (var playButton in playButtons)
            {
                playButton.Click();
                await Task.Delay(2000); // Use Task.Delay for async
            }
        }
    }
    catch (WebDriverException ex)
    {
        Console.WriteLine($"WebDriver exception occurred: {ex.Message}");
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Exception occurred: {ex.Message}");
    }
}

Additional Tips:

  • ChromeDriver Version: Ensure your ChromeDriver is compatible with your version of Chrome. You can download the latest version from here.
  • NuGet Packages: Make sure you are using the latest versions of Selenium.WebDriver and Selenium.WebDriver.ChromeDriver from NuGet.

If you continue to face issues, providing the full error message and stack trace can help with more precise troubleshooting.
