Windows phone webcontrol format exception

Question

I have been using this code for a while working perfectly in my windows phone 7 app im constructing. However all of a sudden it stops working and gives me a format exception error? What i have i been doing wrong since i haven't change a bit in this code since it last worked perfectly?

String url = String.Format("http://www.bing.com/search?q={0}"); 
        webBrowser1.Source = (new Uri(string.Format(url), UriKind.Absolute));

Answer 1

You use the String.Format method but you don't specify any argument after the string.

I think you are trying to do something like

String url = String.Format("http://www.bing.com/search?q={0}", keyword);
