The simplest way would be to create a WebClient object and call its DownloadString method, although if you need anything other than a simple request/response, you may have to use HttpWebRequest to craft your request.

Not exactly sure what's being asked, but don't you just want to open a tcp connection to the correct port (typically 80) of the webserver, write a 'POST' of the correct variety and then read the response data?

If so, look for http helper classes/libraries that are available in C#

you can use httpwebrequest class or webclient class, its in system.net namespace.

WebClient client = new WebClient();
UTF8Encoding encoding1 = new UTF8Encoding();
byte[] downloadDataInBytes = client.DownloadData("http://negaweblog.wordpress.com");
string websitesource = encoding1.GetString(downloadDataInBytes);
