How to get InnerText of IFrame from another site?

Question

I am trying to do some screen-scraping of a website. The content that I want to get is inside of an IFrame. How do I get the InnerText or HTML that is being displayed inside of the IFrame?

I am using .Net 4.0 and C#. I want to be able to do this from a WinForm.

I tried this, but can't find where to get the actual data from...

    void PageCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        WebBrowser b = sender as WebBrowser;
        string response = b.DocumentText;

        HtmlElement element = b.Document.GetElementById("profileFrame");
        if (element != null)
        {
            // do something with the data
        }
    }

I've tried searching through the element but couldn't find any of the HTML. Is this possible?

The contents of the iframe isn't included in the first document. You would need to make a second request to the source address of the iframe to get the content displayed in the iframe.
