Select a value from drop down using Selenium WebDriver C# [duplicate]

Question

I am having tough time in selecting value from drop down using C# binding of WebDriver. I have worked on neither C# nor WebDriver in past. I am using WebDriver - Selenium-dotnet2.0b3 with Visual Studio C# 2010 Express edition. I have added WebDriver.Common, WebDriver.Firefox and WebDriver.Remote to my solution. I tried using this -

IWebElement dateOfBirth = webdriver.FindElement(By.Id("join_birth_day"));
List<IWebElement> dateOfBirthOptions = (List<IWebElement>)dateOfBirth.FindElement(By.TagName("option"));

foreach(IWebElement dateOfBirthOption in dateOfBirthOptions)  
{
    if (dateOfBirthOption.Equals("3"))
    {
        dateOfBirthOption.Select();
    }
}

But got to see error, when running my solution in NUnit

LiveCams.CreateAccount.createAccount:
System.InvalidCastException : Unable to cast object of type 'OpenQA.Selenium.Firefox.FirefoxWebElement' to type 'System.Collections.Generic.List`1[OpenQA.Selenium.IWebElement]'.

And if I don't cast then would not be able to even build the solution. I guess I am missing some thing trivial here. Any one who could guide me here? Drop down selection used to be so simple in Selenium 1.0 :-/

Answer 1

To select an Option from Drop Down use the below code

1. To select a value based on Text

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

2. To select a value based on Value

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

3. To select a value based on Index

   new SelectElement(driver.FindElement(By.XPath(""))).SelectByIndex(0);

1) Using a SelectElement as already commented - How to select an option from drop down using Selenium WebDriver C#? The SelectElement belongs to the OpenQA.Selenium.Support.UI namespace.

2) You could also do something like this with css selectors:

WebElement dateOfBirth =  webdriver.FindElement(By.Id("join_birth_day"))
                              .FindElement(By.CssSelector("option[value='3']")).Select();
