Question

I’m using selenium webdriver, C#.

Is it possible to make work webdriver with Firefox select file dialog?
Or must I use something like AutoIt?

Answer 1

If you are trying to select a file for upload Selenium 2 supports HTML file inputs. For example:

HTML

<input type="file" id="uploadhere" />

Selenium Code

IWebElement element = driver.FindElement(By.Id("uploadhere"));
element.SendKeys("C:\\Some_Folder\\MyFile.txt");

Basically you “type” (with SendKeys) the full file path to the file input element. Selenium handles the file selection dialog for you.

However if you want to manipulate an arbitrary file selection dialog, then like Anders said, you have to go outside of Selenium.
