How to get all options in a drop-down list by Selenium WebDriver using C#?

Question

I'm new to both C# and Selenium WebDriver.

I know how to select/click on an option in a drop-down list, but I've a problem before that. Since the drop-down list is dynamically generated, I have to get all options/values from the list before running each case.

Is there anyone kindly tell me how to get all values/options from a drop-down list. I'm using IE and I didn't find any class which supports method to get values/options in Selenium.IE namespace for C#.

My example: A list contains several time zones:

<TD>
  <select name = "time_zone">
    <option value "-09:00"><script>timezone.Alaska</script></option>
    <option value "+00:00"><script>timezone.England</script></option>
    <option value "+02:00"><script>timezone.Greece</script></option>
    <option value "+05:30"><script>timezone.India</script></option>
  </select>
<TD>

This is a drop-down list in an IE page and how to get the dynamically generated time zone list?

My code:

IWebElement elem = driver.FindElement(By.XPath("//select[@name='time_zone']"));
List<IWebElement> options = elem.FindElements(By.TagName("option"));

C# just pops an Error: Cannot implicitly covert type 'OpenQA.Selenium.IWebElement' to 'System.Collections.Generic.List'. An explicit conversion exists (are you missing a cast?).

thanks.

Answer 1

You can try using the WebDriver.Support SelectElement found in OpenQA.Selenium.Support.UI.Selected namespace to access the option list of a select list:

IWebElement elem = driver.FindElement(By.XPath("//select[@name='time_zone']"));

SelectElement selectList = new SelectElement(elem);
IList<IWebElement> options = selectList.Options;

You can then access each option as an IWebElement, such as:

IWebElement firstOption = options[0];
Assert.AreEqual(firstOption.GetAttribute("value"), "-09:00");

Answer 2

Select select = new Select(driver.findElement(By.id("searchDropdownBox")));

select.getOptions();//will get all options as List<WebElement>
