e_driver.register（eventListener）;

Question

我以前使用Java在Selenium中使用了WebEventListner，但我的工作场所使用c＃。我在'register'e_driver.register（eventListener）;遇到错误

请帮忙一些C＃。

namespace TestFramework.Utils
{
    public class WebEventListener
    {
        public static void beforeNavigateTo(String url, IWebDriver driver)
        {
            Console.WriteLine("Before navigating to: '" + url + "'");
        }

        public static void afterNavigateTo(String url, IWebDriver driver)
        {
            Console.WriteLine("Navigated to:'" + url + "'");
        }
}

 [OneTimeSetUp]
        public void InitializeOnce()
        {
            PropertiesCollection.driver = BrowserFactory.PrepareBrowser(Config.browser);
            driver = PropertiesCollection.driver;

            e_driver = new EventFiringWebDriver(driver);
            eventListener = new WebEventListener();
            e_driver.register(eventListener);
            driver = e_driver;
        }

C＃的语法与Java根本不同。由于C# natively supports events的语法，EventFiringWebDriver的.NET实现利用了它们。此外，事件名称会有所不同，以使.NET开发人员对.NET绑定感到“自然”。您想要的内容如下：

public IWebDriver CreateEventFiringDriver(IWebDriver driver)
{
    // Assume driver is a valid IWebDriver instance.
    var eventDriver = new EventFiringWebDriver(driver);
    eventDriver.Navigating += NavigatingEventHandler;
    eventDriver.Navigated += NavigatedEventHandler;
    return eventDriver;
}

private void NavigatingEventHandler(object sender, WebDriverNavigationEventArgs e)
{
    Console.WriteLine("Before navigating to: '" + e.Url + "'");
}

private void NavigatedEventHandler(object sender, WebDriverNavigationEventArgs e)
{
    Console.WriteLine("Navigated to:'" + e.Url + "'");
}
