Selenium C＃找不到ID或标题

Question

I manage to open a firefox browser, go to http://www.google.com/ search for "Bath Fitter". When i see a bunch of links, i want to in fact click on an item of the top menu provided by Google, Images. Images is located next to Map Videos News... How can i have it click on Images?

Below is my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;   
using OpenQA.Selenium.Firefox;

namespace SeleniumHelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            IWebDriver driver = null;
            try
            {
                driver = new FirefoxDriver();
                driver.Navigate().GoToUrl("http://www.google.com/");
                driver.Manage().Window.Maximize();

                IWebElement searchInput = driver.FindElement(By.Id("gbqfq"));
                searchInput.SendKeys("Bath Fitter");
                searchInput.SendKeys(Keys.Enter);

                searchInput.FindElement(By.Name("Images"));
                searchInput.Click();
                driver.Close();

            }

            catch (Exception e)
            {
                Console.WriteLine("Exception ****" + e.ToString());

            }
        }
    }
}

Answer 1

More specifically you can also write your selector pointing from Top Navigation. This is the XPath.

.//*[@id='hdtb_msb']//a[.='Images']

try this;

driver.FindElement(By.XPath(".//*[@id='hdtb_msb']//a[.='Images']"));

EDIT: Even though the selectors above were correct your code was not working because of the second page was taking too long to load. There you need to wait for the the element to be in ready state and an implicit wait is needed. Change the code in your try block and replace with mine and try

driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.google.com/");
driver.Manage().Window.Maximize();

IWebElement searchInput = driver.FindElement(By.Id("gbqfq"));
searchInput.SendKeys("Bath Fitter");
searchInput.SendKeys(Keys.Enter);

//this is the magic
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
By byImage = By.XPath(".//*[@id='top_nav']//a[.='Images']");
IWebElement imagElement =
                    new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementExists(byImage));
imagElement.Click();

Answer 2

Try something like this...

IList<IWebElement> links = driver.FindElements(By.TagName("a"));
links.First(element => element.Text == "Images").Click();
