Default Determining if a Remote File Exists

Hello Everyone and thanks for your help in advance. I am working on a project that displays images from a remote server. In the event an image does not exist, I need to display a default image in its place. My question is how do I determine if the file exists in the first place? The file.exists method does not work for this as I need to reference the photo in a format such as http://www.somesite.com/images/image.jpg. Any ideas on how to efficiently accomplish this would be greatly appreciated.

file.exist works for local file system, if you want to check the remote file, then use is this way

//Make reference to this
using System.Web;

//Check the content length.
string sMonitoringURI = "http://www.somesite.com/images/image.jpg";
WebRequest wrq = WebRequest.Create(sMonitoringURI);

//Begin: Only needed if you are connecting to internet via proxy
WebProxy wp;
wp = new WebProxy("", 8080);
wrq.Proxy = wp;

WebResponse wrp;
wrp = wrq.GetResponse();
long l = wrp.ContentLength; //Over Here

And rest as you know already.

I guess I have understood your problem, If not let me know will try to fix it in better way. Hope this helps.

With Regards,
Raghavendra Mudugal
