WebClient can't download string

Question

Why does this not works -

"The underlying connection was closed: The connection was closed unexpectedly"

 static void Main() { using (var client = new WebClient()) { try { Console.WriteLine(client.DownloadString("http://oz.by/books/more10176026.html")); } catch (Exception e) { throw; } } }

Usual GET requests are OK. check it here

Can you use a web debugger like Fiddler and check what's going on with the request? That would probably give a hint. — Pierre-Luc Pineault

The server seems to choke because there is no User Agent header. This fixes it:

using (var client = new WebClient()) { try { //Add your user agent of choice. This is mine, just as an example. client.Headers.Add(HttpRequestHeader.UserAgent, "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.73.11 (KHTML, like Gecko) Version/7.0.1 Safari/537.73.11"); Console.WriteLine(client.DownloadString("http://oz.by/books/more10176026.html")); } catch (Exception e) { throw; } }

yes, this works. I have followed msdn, and this was my mistake)) msdn.microsoft.com/en-us/library/fhd1f0sw(v=vs.110).aspx
