StreamWriter and httpwebrequest

[Octavio Filipe]

hi there,

could anyone explains to me what this does?


HttpWebRequest httpWebRequestLogin =
HttpWebRequest.Create(LOGIN_URL_LOGIN) as HttpWebRequest;

string postData = String.Format(USERNAME);
Encoding enc = Encoding.GetEncoding("ASCII");
byte[] data = enc.GetBytes(postData);

StreamWriter requestWriter = new
StreamWriter(httpWebRequestLogin.GetRequestStream());
requestWriter.Write(data);
requestWriter.Close();


Thanks in advance,
o.f

It is sending data to the url passed to the .Create method.
It encodes the data into a byte array. Then, gets a hold of
RequestStream and uses the StreamWrite to write to it.

Here's another sample that sends data over http
and then gets a response. Look for the Upload
method:

Note that this way to write to the request stream is rather weird.
Writing an ASCII encoded byte array to a UTF-8 StreamWriter, which has
no concept of writing bytes and happily calls ToString()...
