使用Selenium WebDriver C＃在下拉列表中选择每个选项

Question

I'm not able to select options in a drop down list. I think I need to have .Select or SelectElement , but there is no such option.

Sample code:

IWebDriver ffbrowser = new FirefoxDriver();
ffbrowser.Navigate().GoToUrl("http://www.amazon.com/");
ffbrowser.Manage().Window.Maximize();

Thread.Sleep(500);

IWebElement ddl = ffbrowser.FindElement(By.Name("url"));
int numofitems = ddl.FindElements(By.TagName("option")).Count;

for (int i = 1; i < numofitems; i++)
{
    ffbrowser.select("TagName = option", "index = i");
}

The "select" in "ffbrowser.select" is reported as an error:

Error 1 'OpenQA.Selenium.IWebDriver' does not contain a definition for 'select' and no extension method 'select' accepting a first argument of type 'OpenQA.Selenium.IWebDriver' could be found (are you missing a using directive or an assembly reference?)

My project references include Selenium.WebDriverBackedSelenium , Thoughtworks.Selenium.Core , WebDriver , WebDriver.Support

and I have

using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Support.UI;

Answer 1

Depending what version of Selenium WebDriver you are using you can use the SelectElement class, which will be included in OpenQA.Selenium.Support.UI .
For example:

SelectElement selector = new SelectElement(element);
selector.SelectByIndex(1);

Where the element is your drop down box.

Answer 2

Here is an example to better illustrate how to get all the items in a drop down list and to select an item from the drop down list.

A sample Html code for drop down list

<select>
  <option>Milk</option>
  <option>Coffee</option>
  <option>Tea</option>
</select>

Code below gets all the items from the drop down list above and selects item 'Coffee'.Logic of the code is as follows

Step 1. Create an interface of the web element tag Step 2. Create an IList with all the child elements of web element tag Step 3. Select the Drop List item "Coffee"

using System;
using System.Collections.Generic;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Support.UI;

namespace SeleniumTests
{
    class DropDownListSelection
    {
        static void Main(string[] args)
        {
            IWebDriver driver = new FirefoxDriver(); 
            driver.Navigate().GoToUrl("http://DropDownList.html");
            IWebElement element = driver.FindElement(By.XPath("//Select"));
            IList<IWebElement> AllDropDownList =    element.FindElements(By.XPath("//option"));
            int DpListCount = AllDropDownList.Count;
            for (int i = 0; i < DpListCount; i++)
            {
                if (AllDropDownList[i].Text == "Coffee")
                 {
                    AllDropDownList[i].Click();
                 }
            }
            Console.WriteLine(DpListCount);
            Console.ReadLine();
        }
    }
}

Answer 3

You can also use:

new SelectElement(driver.FindElement(By.Id("")).SelectByText(""));

Or:

new SelectElement(driver.FindElement(By.Id("")).SelectByValue(""));

Answer 4

Use the below simple sample code:

String Input="Value to Select"; 
String xPathVal="@["id=Samplexpath"]"; 
IWebElement TargetElement = driver.FindElement(By.XPath(xPathVal)); 
SelectElement dropdown = new SelectElement(TargetElement); 
dropdown.SelectByText(Input.Trim());

Answer 5

This works perfectly ...

SelectElement selector = new SelectElement(element);
selector.SelectByIndex(1);

Where the element is your drop down box.
