How to log into a website with c#

This works. What I've done here is log in manually then using fiddler copy and pasted the cookies and hardcoded them. This logs straight into the game page as I'm wanting it to. This isn't really a solution though as these cookies are specific to this one user account and I'm guessing they will expire anyway.

Seems like it's the first part of the code logging in that doesn't work properly. The cookies that come back from this passage of code look completely different to the ones that show up in fiddler so looks like it's just not logging in.



string newloginUri = "http://www.conquerclub.com/game.php?game=13025037";
            HttpWebRequest newrequest = (HttpWebRequest)WebRequest.Create(newloginUri);
            newrequest.Proxy = null;
            newrequest.CookieContainer = new CookieContainer();
            newrequest.CookieContainer.Add(new Uri("http://www.conquerclub.com"), new Cookie("PHPSESSID","86bte1ipainiq760vm2flv4h13"));
            newrequest.CookieContainer.Add(new Uri("http://www.conquerclub.com"), new Cookie("phpbb3_jer7c_u", "648113"));
            newrequest.CookieContainer.Add(new Uri("http://www.conquerclub.com"), new Cookie("phpbb3_jer7c_k", ""));
            newrequest.CookieContainer.Add(new Uri("http://www.conquerclub.com"), new Cookie("phpbb3_jer7c_sid", "3eebb0771a68c4a58581e495c34b2c93"));
            using (HttpWebResponse newresponse = (HttpWebResponse)newrequest.GetResponse())
            using (Stream resSteam = newresponse.GetResponseStream())
            using (StreamReader sr = new StreamReader(resSteam))
                richTextBox1.Text = sr.ReadToEnd();

Yeah figured that I need to do something with the cookies. Tried this that I found on another site but it's still just bringing back the login page.

Really struggling to figure out how to do this so any help would be greatly appreciated.

private void toolStripButton1_Click(object sender, EventArgs e)
        {
            string loginUri = "http://www.conquerclub.com/login.php";
            string username = "testuser1";
            string password = "testing";
            string reqString = "username=" + username + "&password=" + password;
            byte[] requestData = Encoding.UTF8.GetBytes(reqString);

            CookieContainer cc = new CookieContainer();
            var request = (HttpWebRequest)WebRequest.Create(loginUri);
            request.Proxy = null;
            request.AllowAutoRedirect = false;
            request.CookieContainer = cc;
            request.Method = "post";

            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = requestData.Length;
            using (Stream s = request.GetRequestStream())
                s.Write(requestData, 0, requestData.Length);

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                if (response.Cookies != null)
                {
                    foreach (Cookie c in response.Cookies)
                        Console.WriteLine(c.Name + " = " + c.Value);
                }
            }

            string newloginUri = "http://www.conquerclub.com/game.php?game=13025037";
            HttpWebRequest newrequest = (HttpWebRequest)WebRequest.Create(newloginUri);
            newrequest.Proxy = null;
            newrequest.CookieContainer = cc;
            using (HttpWebResponse newresponse = (HttpWebResponse)newrequest.GetResponse())
            using (Stream resSteam = newresponse.GetResponseStream())
            using (StreamReader sr = new StreamReader(resSteam))
                richTextBox1.Text = sr.ReadToEnd();
        }

Just I hooked fiddler and your site request. Your site expects lot of cookies stuff.
During your web request from C#, how you're managing cookies?
