如何选择一个选项从下拉使用 Selenium WebDriver C # ？

我正在尝试我的网络测试选择一个选项。一个例子可以在这里找到: http://www.tizag.com/phpT/examples/formex.php

除了选择一个选项部分，一切都很好。如何选择一个选项的价值或标签？

我的准则:

using OpenQA.Selenium.Firefox;
using OpenQA.Selenium;
using System.Collections.ObjectModel;
using System.Text.RegularExpressions;
using System.Threading;
using System.Diagnostics;
using System.Runtime.InteropServices;


class GoogleSuggest
{
static void Main()
{
IWebDriver driver = new FirefoxDriver();


//Notice navigation is slightly different than the Java version
//This is because 'get' is a keyword in C#
driver.Navigate().GoToUrl("http://www.tizag.com/phpT/examples/formex.php");
IWebElement query = driver.FindElement(By.Name("Fname"));
query.SendKeys("John");
driver.FindElement(By.Name("Lname")).SendKeys("Doe");
driver.FindElement(By.XPath("//input[@name='gender' and @value='Male']")).Click();
driver.FindElement(By.XPath("//input[@name='food[]' and @value='Chicken']")).Click();
driver.FindElement(By.Name("quote")).Clear();
driver.FindElement(By.Name("quote")).SendKeys("Be Present!");
driver.FindElement(By.Name("education")).SendKeys(Keys.Down + Keys.Enter); // working but that's not what i was looking for
// driver.FindElement(By.XPath("//option[@value='HighSchool']")).Click(); not working
//  driver.FindElement(By.XPath("/html/body/table[2]/tbody/tr/td[2]/table/tbody/tr/td/div[5]/form/select/option[2]")).Click(); not working
// driver.FindElement(By.XPath("id('examp')/x:form/x:select[1]/x:option[2]")).Click(); not working


}

You must create a select element object from the drop down list.

 using OpenQA.Selenium.Support.UI;


// select the drop down list
var education = driver.FindElement(By.Name("education"));
//create select element object
var selectElement = new SelectElement(education);


//select by value
selectElement.SelectByValue("Jr.High");
// select by text
selectElement.SelectByText("HighSchool");

Other way could be this one:

driver.FindElement(By.XPath(".//*[@id='examp']/form/select[1]/option[3]")).Click();

and you can change the index in option[x] changing x by the number of element that you want to select.

I don't know if it is the best way but I hope that help you.

This is how it works for me (selecting control by ID and option by text):

protected void clickOptionInList(string listControlId, string optionText)
{
driver.FindElement(By.XPath("//select[@id='"+ listControlId + "']/option[contains(.,'"+ optionText +"')]")).Click();
}

use:

clickOptionInList("ctl00_ContentPlaceHolder_lbxAllRoles", "Tester");

You just need to pass the value and enter key:

driver.FindElement(By.Name("education")).SendKeys("Jr.High"+Keys.Enter);

Adding a point to this- I came across a problem that OpenQA.Selenium.Support.UI namespace was not available after installing Selenium.NET binding into the C# project. Later found out that we can easily install latest version of Selenium WebDriver Support Classes by running the command:

Install-Package Selenium.Support

in NuGet Package Manager Console, or install Selenium.Support from NuGet Manager.

To Select an Option Via Text; 

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

To Select an Option via Value: 

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

If you are looking for just any selection from the drop-down box, I also find "select by index" method very useful.

if (IsElementPresent(By.XPath("//select[@id='Q43_0']")))
{
new SelectElement(driver.FindElement(By.Id("Q43_0")))**.SelectByIndex(1);** // This is selecting first value of the drop-down list
WaitForAjax();
Thread.Sleep(3000);
}
else
{
Console.WriteLine("Your comment here);

Selenium WebDriver C# code for selecting item from Drop Down:

IWebElement EducationDropDownElement = driver.FindElement(By.Name("education"));
SelectElement SelectAnEducation = new SelectElement(EducationDropDownElement);

There are 3 ways to select drop down item: i)Select by Text ii) Select by Index iii) Select by Value

Select by Text:

SelectAnEducation.SelectByText("College");//There are 3 items - Jr.High, HighSchool, College

Select by Index:

SelectAnEducation.SelectByIndex(2);//Index starts from 0. so, 0 = Jr.High 1 = HighSchool 2 = College

Select by Value:

SelectAnEducation.SelectByValue("College");//There are 3 values - Jr.High, HighSchool, College

 var select = new SelectElement(elementX);

var click = (
from sel in select
let value = "College"
select value

{
if (AllDropDownList[i].Text == "nnnnnnnnnnn")
{
AllDropDownList[i].Click();
_browserInstance.ScreenCapture("nnnnnnnnnnnnnnnnnnnnnn");
