Log in and download file

Hello Everyone,

I'm trying to write a C# program that can login and download a file from a website.

Here is my code:

using System;
using System.Collections.Specialized;
using System.Net;
using System.Windows.Forms;
namespace CodeProjectDownload
{
public class CookiesAwareWebClient : WebClient
{
public CookieContainer CookieContainer;
public CookieContainer MyProperty
{
get { return CookieContainer; }
set { CookieContainer = value; }
}
public CookiesAwareWebClient()
{
CookieContainer = new CookieContainer();
}
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
((HttpWebRequest)request).CookieContainer = CookieContainer;
return request;
}
}
public class Program
{
private static void Download(string email, string password, string destination, string downloadUri)
{
using (CookiesAwareWebClient client = new CookiesAwareWebClient())
{
NameValueCollection values = new NameValueCollection();
values.Add("Email",email );
values.Add("Password", password);
values.Add("x", "10");
values.Add("y", "10");
values.Add("login", "login");
// We authenticate first
client.UploadValues("https://www.codeproject.com/script/Membership/LogOn.aspx?rp=%2f", values);
// Now we can download
//string modifieduri = "http://www.codeproject.com/script/articles/download.aspx?file=" + downloadUri.Replace("http://www.codeproject.com","") + "&rp=";
string modifieduri = "https://www.codeproject.com/KB/buttons/1087610/FontAwesomeImageSample.zip";
Console.WriteLine("url " + modifieduri);
string filename = System.IO.Path.GetFileName(downloadUri);
string filepathname = System.IO.Path.Combine(destination, filename);
client.DownloadFile(modifieduri, filepathname);
}
}
static void Main(string[] args)
{
try
{
Download("[email protected]", "mfAwItJZ9+xZ", @"C:\Users\lswennen\Work Folders\WIP\Archiving\BIMCo connection", "/KB/buttons/1087610/FontAwesomeImageSample.zip");
//Console.ReadLine();
MessageBox.Show("ok");
} catch (Exception e)
{
Console.WriteLine("{0}", e);
MessageBox.Show("pas ok");
}
}
}
}

And when I run it, a "zip file" is downloaded but "corrupted". When I open it with the notepad, it looks like a html source code. So I added ".html" extension" and when I open it it shows the webpage which will start the downloading. If I wait a bit my browser try to download the file but it fails because it's from my ".html" file.

What am I doing wrong to download the html source code and not the file ?

Thanks in advance.

if you want to download from website i recommend to use gecko browser (for filling the inputs) and html Agility pack for get the data
