What's wrong with my HttpWebRequests? - fortress1999 - May 27, 2016
Code
HttpWebRequest peticionGalleta = (HttpWebRequest)WebRequest.Create("twitter.com/sessions");
peticionGalleta.ProtocolVersion = HttpVersion.Version11;
peticionGalleta.Method = "POST";
peticionGalleta.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
peticionGalleta.ContentLength = 238;
peticionGalleta.ContentType = "application/x-www-form-urlencoded";
peticionGalleta.Host = "twitter.com";
peticionGalleta.Referer = "twitter.com/login";
peticionGalleta.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0";
string postData = "session%5Busername_or_email%5D=" + textBox1.Text + "&session%5Bpassword%5D=" + textBox2.Text + "&remember_me=1&redirect_after_login=";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
StreamWriter sw = new StreamWriter(peticionGalleta.GetRequestStream());
sw.Write(postData, 0, byteArray.Length);
sw.Close();
HttpWebResponse respuestaGalleta = (HttpWebResponse)peticionGalleta.GetResponse();
StreamReader lectorGalleta = new StreamReader(respuestaGalleta.GetResponseStream());
string html = lectorGalleta.ReadToEnd();
MessageBox.Show(html.ToString());The messagebox doesn't display anything (The links are fine, I just can't post them fully on HF)

I'm not dealing with this kind of method, but, isn't it an async method?

Nothing in his code is asynchronous at all.
But why do you have a GET variable that isn't assigned?
Code
&redirect_after_login=And why are you hardcoding ContentLength as 238?
Code
peticionGalleta.ContentLength = 238;^ You have no idea the length of the textbox inputs at compile time, so that is silly... :S
You don't know what you're doing and once you get into authentication you'll be lost.

Yes DeadLock is right, well other than whyen he said it was GET variables. It's a POST variable since the method is POST.
Also op, don't set the content length, the webrequest will set it for you automatically after you write the data to the request stream.
Also, the main reason yours isn't working is because you most likely haven't made an initial request to gather the session cookies. Which you should include in the subsequent request.

Ahh, I got threads mixed up. Was reading another one where some guy wanted to send a bunch of threaded GET requests in C.

Where do you think I should learn about HttpWebRequests? Thanks

First you have to understand HTTP. From there it should be fairly easy to learn the .NET classes.
