      To Handle dropDownlist in selenium webdriver, We have to use "SelectElement" class in c#.Net.
It is located in package of "OpenQA.Selenium.Support.UI".

There are different representation of "Select" class in C#.Net and Java.

In C#:
Ex:
     SelectElement  se  = new SelectElement( element ) ;

In Java:
Ex:
     Select se = new select( element ) ;

We can Select element/option from DropDown List by 3-ways:

1. SelectByIndex( int )       -   Select an option by index position.
2. SelectByValue( String )  -   Select an option by the value.
3. SelectByText( String )    -   Select an option by displayed Text.

To demonstrate how to handle drop down list. I am going to consider "Facebook" application. Because it has three drop down list 1-Month  2-Day & 3-Year(Birthdate).
In Below example I want to select Jun 21 1984 as a Birthdate,


Example:
using System;
using NUnit.Framework;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Interactions;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;

namespace SleniumWebDriverWithCSharpTutorial
{
    [TestFixture]
    public class HandlingDropDownList
    {
        IWebDriver driver = null ;
        IWebElement element = null ;

        [SetUp]
        public void SetUP()
        {
            driver = new FirefoxDriver();
            driver.Manage().Window.Maximize();
            driver.Url = "http://facebook.com";
        }

        [Test]
        public void TestDropDownList()
        {
            //wait for to get Facebook Home page title
            WebDriverWait wait = new WebDriverWait(driver,TimeSpan.FromSeconds(10));
            wait.Until(ExpectedConditions.ElementIsVisible(By.Id("month")));

            //Handling Drop Down List to select Birth Month as "Jun".
            SelectElement se = new SelectElement(driver.FindElement(By.Id("month")));
            foreach (IWebElement item in se.Options)
            {
                if (item.Text == "Jun")
                {
                    item.Click();
                    break ;
                }                   
            }
     
           //Set previous element reference to b=null
            se = null ;
            //select By using Index Position
            se = new SelectElement(driver.FindElement(By.Id("day")));
            se.SelectByIndex(21);


            //Set previous element reference to b=null
            se = null ;
            //Select By Using Value
            se = new SelectElement(driver.FindElement(By.Id("year")));
            se.SelectByValue("1984");           
        }

        [TearDown]
        public void TearDown()
        {
            if (element != null)
                element = null ;
            driver.Close();
        }
    }
}
