Question

I’m trying to use the WebClient class to download a html file from another website and present it as a text stream, But I’m getting a security error, what am I doing wrong, or is this another one of Silverlights security ‘Features’

[code]

namespace ImageScrape { public partial class Page : UserControl { public Page() { InitializeComponent();

    }      private void UserControl_Loaded(object sender, RoutedEventArgs e)     {         WebClient cl = new WebClient();         cl.OpenReadCompleted += new OpenReadCompletedEventHandler(cl_OpenReadCompleted);         cl.OpenReadAsync(new Uri(@'http://www.google.co.uk/',UriKind.Absolute));      }      void cl_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)     {         testTextBlock.Text = e.Result.ToString();     } } 

}

[/code]

EDIT

Thanks guys, I was really hoping I wouldn’t have to create this as a WCF service as 1) I only know the basics and 2) The idea is that you can use this .xap without having to connect to a central server, mainly because for this I don’t have a server that I could host a WCF service on.

Does anyone know a way to get around this, or anywhere that would host a WCF service for free?

Answer 1

I think there are security issues with going directly to another site from the silverlight client.

The best work around for this would be to move this code into a web service and then serve the content you require to client from there.
