I have the following HTML code snippet:

ThiscodebelongstoapageofanAirOS(internetradio)radio.

IneedtoreferencethisbuttoninsideaprogrammadeinWindowsFormsandmakeafunctionforittobeexecutedandtheradioreboot.

Iwasonlyabletogetelementswithanidattribute,asfollows:

HtmlElementusername=webBrowser1.Document.GetElementById("username");

How do I reference this button that has no "id" field? Remembering that the HTML code is not mine, I can not edit it and put the "id" field.

I'm currently using the WebBrowser component, would I have some other way to access the radio and reboot without using WebBrowser?

Thank you.

Try to do this:

var button = myWebBrowser.Document.GetElementsByTagName("input")
         .Cast<HtmlElement>()
         .FirstOrDefault(m => m.GetAttribute("type") == "submit");

You can try to get this "button" by type ..

var inputs = document.getElementsByTagName('input');

In this case you have the inputs of the screen. This can go wrong if you have more inputs than you want to select, then you would need some unique identifier.
