Hi Guys,

I used following code to download file from secured site but file created on folder @"C:\Downloads\Filename" show HTML tags like this

<HTML>
<HEAD><LINK rel="stylesheet" type="text/css" name="defaultstyle" href="/cehttp/html/style.css">
<TITLE>Servlet Response Message</TITLE></HEAD>
<BODY>
<H2 align=center><H2>
<HR>
You are not logged on. Please logon first.
<HR>
</BODY></HTML>

instead of the actual file content.

try
       {
           WebClient client = new WebClient();
           client.Credentials = new System.Net.NetworkCredential("username", "password");
           byte[] pageData = client.DownloadData("url");
           string pageHtml = Encoding.ASCII.GetString(pageData);
           Console.WriteLine(pageHtml);

           client.DownloadFile("url", @"C:\Downloads\071213.ACCT");
       }
       catch (WebException webEx)
       {
           Console.WriteLine(webEx.ToString());
           if (webEx.Status == WebExceptionStatus.ConnectFailure)
           {
               Console.WriteLine("Are you behind a firewall?  If so, go through the proxy server.");
           }
       }

That's some mechanism on the server side: they check somehow that you are logged in, and your username ans password are not enough. I can only guess that they might use cookies, check referers, check session variables,...
