How can you automate Firefox from C# application?

Start with the simplest task of capturing the URL in Firefox from a C# application. It appears using user32.dll Windows API functions will not work as is the approach for capturing the URL within IE.

回答1:

Should I need to do a capture of the URL with AutoHotkey, for example, I would send Ctrl+L (put focus in address bar and highlight content) and Ctrl+C (copy selection to clipboard). Then you just read the clipboard to get the info.

For more complex tasks, I would use Greasemonkey or iMacros extensions, perhaps triggered by similar keyboard shortcuts.

回答2:

WatiN has support for Firefox.

回答3:

WebAii can automate FireFox, including setting and retrieving the URL

回答4:

It appears to be very beta-ey, but someone built a .net connector for mozrepl. Actually, the mozrepl codebase just moved to github. But mozrepl lets you issue commands to the Firefox's XUL environment.

回答5:

Try Selenium (the Google testing engine - http://seleniumhq.org/) You can record task (Webpages UI related) done in Firefox and the convert the recording into a C# source :)

回答6:

You can use Selenium WebDriver for C #.

This is a cross-platform API that allows you to control various browsers using APIs for Java, C#, among others.

One Microsoft tool I ran into:

UI Automation, as part of .NET 3.5 http://msdn.microsoft.com/en-us/library/aa348551.aspx

Here's an example: http://msdn.microsoft.com/en-us/library/ms771286.aspx

I don't have UI Spy on my pc to interrogate Firefox, so I don't know if this will help out with your user32.dll problem.
