Question

How can I check a File exits in a web location in ASP.Net(in a different web application, but same web server), currently I doing like this. Is there any better way of doing this?

using (WebClient client = new WebClient())
{
            try
            {
                Stream stream = client.OpenRead("http://localhost/images/myimage.jpg");
                if (stream != null)
                {
                    //exists
                }
            }
            catch
            {
                //Not exists
            }
}

If a file is accessible via HTTP, you can issue a HTTP HEAD requrest for that particular URL using HttpWebRequest. If HttpWebResponse.StatusCode will be 200, than file is there.

EDIT: See this on why GetResponse throws stupid exceptions when it actually should not do that.
