使用Webbrowser控件自动在网站中登录表单

Question

I'm automating form login in a certain site using the WebBrowser control. Having the client id of the textbox, password and button login, I'm able to do it.

The question is, can I still do it without identifying the id of the button and simulate a click?

Answer 1

Yes; you can call the submit method of the form object.

For example:

browser.Document.Forms[0].Invokemember("submit");

To set the name and password, loop through

browser.Document.Forms[0].GetElementsByTagName("input")

Tpassword will have the type attribute equal to password , and the username will probably be just before the password.

Answer 2

There is no way you could do this without being able to identify the controls somehow. You would need the ids, or you would need to be told exactly where in the DOM they were located by some other means.
