Looking for an example of System.Net

[Thanh Nguyen]

Hi Josh,
With Wininet, I would first connect to a site, then use HttpOpenRequest() to
ask
for some page in that site :

hdl = InternetOpen(...) ;
session = InternetConnect(hdl, "www.somesite.com", port, ...) ;
req = HttpOpenRequest(session, "POST", "page1.asp", ...);

With System.Net, I would do the following:

HttpWebRequest req = (HttpWebRequest)
WebRequestFactory.Create(www.somesite.com);
WebResponse resp = req.GetResponse();

The System.Net does not have the notion of session.
Does that means that the session is implicitly kept if I stay in the site ?

Could you show me some code equivalent tot he Wininet fragment above?

Thanks,
tom.

Hey :)

OK, first of all, I am not totally sure why you would want to keep the
session alive (remember, HTTP is a session-less protocal)...but here's one
implementation using a Stream:

HttpWebRequest req = (HttpWebRequest)
WebRequestFactory.Create("www.microsoft.com");
HttpWebResponse resp = req.GetResponse();
resp.GetResponseStream(); // provides a stream object which can be used to
access the data in a stream

To go beyond that and use a Socket connection to the server like you do in
WinInet, that's a whole different ball of wax, but I think it is what you
are trying to accomplish. To begin, take a look at the System.Net.Sockets
class. That contains all of the underlying classes to allow direct socket
connections to servers. The one you will probobly use is
System.Net.Sockets.TCPClient. For example:

TCPClient tc = new TCPClient("www.microsoft.com", 80);
tc.Connect();
NetworkStream myStream = tc.GetStream();
myStream.BeginRead(...); // and other NetworkStream methods, etc.

Hope that helps!

I need a session in order for the session cookie.
(without it you cannot have session cookies).

I guess that the simplest would be to write a test program.
I will post my result, unless somebody responded before.

thanks Josh.
