Download a file using WebBrowser Control

i'm trying to automate the file download from a web page, the problem is, that web return directly the file. for example, http://www.someweb.com/generatefile.aspx, when i navigate to that page, a file is returning. I tried with WebClient, but didn't work, always give error 500, however if i try through whit IExplorer or Firefox, work well. So, i trying with WebBrowser control, which i made all other things, such as login to web.

WebClient client = new WebClient();
client.DownloadFile(url, "D:/ss.pdf");  //Here error 500

and with WebBrowser

WebBrowser wb = new WebBrowser();
wb.FileDownload += new EventHandler(wb_FileDownload); //in the event handler i not found how save the file
wb.Navigate(url);

Thanks for any help.

You'll need to do a bit more configuring, but I would recommend using the HttpWebRequest instead.

If you know the expected file type, then you can create a file on the filesystem with the known type and get a stream reference for it. Then just write the response stream returned by HttpWebRequest::GetResponse().

I've tried using the classes you mentioned in the past, but always fall back on using HttpWebRequest and HttpWebResponse. As I said earlier, they are a bit more low level, but in a lot of scenarios, the additional control over the low level HTTP functions has been helpful in my experience.

Have you tried using an FTPWebRequest? The WebBrowser is made for GUI style interaction, not really for automation...
