To enter text in textbox we need locator string of that particular textbox. To get locator string you need to your FireFox Element Locator Add-on.

In this example first we open website 'www.google.com'. After that, we locate search textbox using locator add-on. Now in C# code we create object of FireFoxDriver Class.

We are using 'FindElement' method of 'FireFoxDriver' Class object, in this object we are finding element using 'XPath'. We are using 'OpenQA.Selenium.By.XPath' method. After finding element we are using 'SendKeys' method to insert text in textbox.
