询问预期条件

Question

   public static IWebElement WaitGetElement(IWebDriver driver, By by, int timeoutInSeconds, bool checkIsVisible = false)
    {
        WebDriverWait webDriverWait = new WebDriverWait(driver, TimeSpan.FromSeconds((double)timeoutInSeconds));
        IWebElement result;
        try
        {
            if (checkIsVisible)
            {
                result = webDriverWait.Until<IWebElement>(ExpectedConditions.ElementIsVisible(by));
            }
            else
            {
                result = webDriverWait.Until<IWebElement>(ExpectedConditions.ElementExists(by));
            }
        }
        catch (NoSuchElementException)
        {
            result = null;
        }
        catch (WebDriverTimeoutException)
        {
            result = null;
        }
        catch (TimeoutException)
        {
            result = null;
        }
        return result;
    }

I Think you are missing this particular Nuget package "SeleniumExtras.WaitHelpers.ExpectedConditions" https://www.nuget.org/packages/DotNetSeleniumExtras.WaitHelpers/3.11.0

You can download it from nuget library or with the link provided. Later as some comments tell you must put an "using" in the code.

I hope this helps
