Image Extraction : uri is too long

Question

I am working on Image Extraction Software from A WebPage . have created a function

 public static void GetAllImages()
        {

            WebClient x = new WebClient();
            string source = x.DownloadString(@"http://www.bbc.com");

            var document = new HtmlWeb().Load(source);
            var urls = document.DocumentNode.Descendants("img")
                                .Select(e => e.GetAttributeValue("src", null))
                                .Where(s => !String.IsNullOrEmpty(s));

            document.Load(source);


        }

It says "Uri is too long " ..

I tried to use Uri.EscapeDataString .. But not getting idea where to put it

Any Help would be appreciated

My bet is that HtmlWeb.Load takes Uri as its parameter while you are feeding it the whole page contents. Also please add description of HtmlWeb class to your question. You're probably using some sore of 3rd party library. — Sergey.quixoticaxis.Ivanov, Jul 22 '16 at 12:34

HtmlWeb.Load takes a URL as its source and deals with the downloading of the content. You don't need a supplementary WebClient to do this, it's all taken care of.

What you are doing is downloading the content, then attempting to use the downloaded content (HTML) as a URL (probably under the assumption that Load means Parse).

So remove

WebClient x = new WebClient();
string source = x.DownloadString(@"http://www.bbc.com");

then change the next line to

var document = new HtmlWeb().Load(@"http://www.bbc.com");

and you'll be good to go.
