图片不是由C＃，WebRequest.Create（url.AbsoluteUri）作为HttpWebRequest下载的；

Question

Previously all Images were downloadable from different website by using

  var request = WebRequest.Create(url.AbsoluteUri) as HttpWebRequest;  

But now,I came across a website

http://www.euroman.dk/gadgets-og-design/det-onsker-vi-os/skyd-360-video-med-din-iphone/

and this Image URL is not downloadable

http://www.euroman.dk/imagecropper.ashx?f=%2fUpload%2feuroman-dk%2fgadgets-og-design%2f2013%2520maj%2fthedot_01.jpg&w=643&h=405&m=1

Can anybody suggest me please what is the reason?

Answer 1

pehaps set the timout with bigger value

request.Timeout = 5000;
request.ReadWriteTimeout = 20000;

Answer 2

your site expects an User-Agent header.

string url = "http://www.euroman.dk/imagecropper.ashx?f=%2fUpload%2feuroman-dk%2fgadgets-og-design%2f2013%2520maj%2fthedot_01.jpg&w=643&h=405&m=1";
using (WebClient wc = new WebClient())
{
    wc.Headers["User-Agent"] = "Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12";
    byte[] data = wc.DownloadData(url);
}
