C# 卷轴

搜索youtube后，我想向下滚动以匹配我要查找的视频，否则我会出错。假设我正在寻找的视频位于页面底部，我必须向下滚动，我无法成功。滚动到页面的末尾，但没有单击视频，这次它继续进入相同的循环

var chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true;

options.AddUserProfilePreference("profile.default_content_setting_values.images", 2);

options.AddArgument("disable-infobars");
options.AddArgument("--disable-extensions");
            
var driver = new ChromeDriver(chromeDriverService, options);
driver.Navigate().GoToUrl("https://www.youtube.com/");

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromMilliseconds(1500));
