selenium-webdriver Locating Web Elements Selecting by multiple criteria [C#]
Example
It's also possible to use selectors together. This is done by using the OpenQA.Selenium.Support.PageObjects.ByChained object:
element = driver.FindElement(new ByChained(By.TagName("input"), By.ClassName("class"));
Any number of Bys can be chained and are used as an AND type selection (i.e. all Bys are matched)
