Read iframe content using Webbrowser C#

I know that I can access all iframes using the following properties of webbrowser: string html = webBrowser1.Document.Window.Frames[0].WindowFrameElement.InnerText;

But I'm struggling with cross-domain restriction.. My document url is like www.subdomain1.sport.com/... And iframes url is like www.subdimain2.sport开发者_C百科.com/...

How to access iframes content and put some text into input tag there?

I think you must refer the following URL to get the content of IFrame which exists on cross domain.
