C# 在Selenium C中获取无头Chrome驱动程序时出错#

我在Selenium C#中使用无头chrome驱动程序时出错。我正在做自动化的网站，其中涉及的用户名和密码。没有无头镀铬，它的性能很好。但当我使用无头镀铬时。主要是给了我错误

{"no such element: Unable to locate element: {\"method\":\"css selector\",\"selector\":\"

当前投资组合可折叠>div>div>div>table>tbody>tr:n子项（6）>td:n子项（1）>div>a>span\“}\n （会话信息：headless chrome=64.0.3282.167..

在此处输入代码

我只在无头chrome中得到这个错误。下面是代码

 var driverService = ChromeDriverService.CreateDefaultService();
            driverService.HideCommandPromptWindow = true;
               ChromeOptions option = new ChromeOptions();
                option.AddArgument("--headless");
                option.AddArgument("--window-size=2160,3840");
            using (var driver = new ChromeDriver(driverService, option))
            {
                WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
                driver.Manage().Timeouts().PageLoad = TimeSpan.FromMinutes(2);
                driver.Navigate().GoToUrl("https://www.wikifolio.com/");
                label1.Text = "Browser is opened now";                
                    try
                    {

                        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMinutes(2);
                        IJavaScriptExecutor main = (IJavaScriptExecutor)driver;
                        Task.Delay(10000);

                    main.ExecuteScript("arguments[0].click();", driver.FindElement(By.XPath("//*[@id=\"page-content\"]/header/div[2]/div/div/nav/div[2]/a[1]")));

                    driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);
                        var username = driver.FindElement(By.CssSelector("input#Username"));
                        username.SendKeys("derhenker55@hotmail.com");

                        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);

                        var password = driver.FindElement(By.CssSelector("input#Password"));
                        Task.Delay(1000);
                        password.SendKeys("password");
                        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);

                        IJavaScriptExecutor loginclick = (IJavaScriptExecutor)driver;
                    Task.Delay(1000);
                    loginclick.ExecuteScript("arguments[0].click();", driver.FindElement(By.CssSelector("form > button.c-button")));

                    }
                    catch(Exception e)
                    {
                    }


            }

希望这有帮助！我运行它没有问题。告诉我这是否对您有帮助

我认为它在java中有所不同。
