Select each option in a drop down using Selenium WebDriver C#
提问by Ben Walker
I'm not able to select options in a drop down list. I think I need to have .Selector SelectElement, but there is no such option.
我无法在下拉列表中选择选项。我想我需要有.Select或SelectElement，但没有这样的选择。
Sample code:
示例代码：
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:
“ffbrowser.select”中的“select”报错：
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?)
错误 1“OpenQA.Selenium.IWebDriver”不包含“select”的定义，并且找不到接受“OpenQA.Selenium.IWebDriver”类型的第一个参数的扩展方法“select”（您是否缺少 using 指令或组装参考？）

Depending what version of Selenium WebDriver you are using you can use the SelectElementclass, which will be included in OpenQA.Selenium.Support.UI.
For example:
根据您使用的 Selenium WebDriver 版本，您可以使用SelectElement该类，该类将包含在OpenQA.Selenium.Support.UI.
例如：
SelectElement selector = new SelectElement(element);
selector.SelectByIndex(1);
Where the elementis your drop down box.
当元素是你的下拉框。

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.
这是一个示例，可以更好地说明如何获取下拉列表中的所有项目并从下拉列表中选择一个项目。
A sample Html code for drop down list
下拉列表的示例 Html 代码
<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
下面的代码从上面的下拉列表中获取所有项目并选择项目'Coffee'。代码逻辑如下
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"
Step 1. 创建 web element 标签的接口 Step 2. 使用 web element tag 的所有子元素创建一个 IList Step 3. 选择 Drop List 项“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();
}
}
}

You can also use:
您还可以使用：
new SelectElement(driver.FindElement(By.Id("")).SelectByText(""));
Or:
或者：
new SelectElement(driver.FindElement(By.Id("")).SelectByValue(""));
回答by Arnab
Use the below simple sample code:
使用下面的简单示例代码：
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());

This works perfectly ...
这完美地工作......
SelectElement selector = new SelectElement(element);
selector.SelectByIndex(1);
Where the element is your drop down box.
元素是您的下拉框。
