Banner Grabbing using telnet or ftp [Almost done]

Does anyone have an idea of how to perform banner grabbing for any website using c# code?

I tried on cmd.exe using telnet command and was able to grab the banner information on the console itself but since it requires dummy enter presses for the result.
I am not able to redirect the result on the web browser.

Any alternative or links will be appreciable.

[edit]
Done using this:

C#

HttpWebResponse myHttpWebResponse = null;
                   try
                   {
                       myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
                   }
                   catch (WebException ex)
                   {
                       myHttpWebResponse = (HttpWebResponse)ex.Response;
                   }
                   txtDisplay.Text = "\n\n"+ myHttpWebResponse.Headers.ToString().Replace("\r\n","\r\n\n");

What do you mean by Banner Grabbing, which content exactly are you trying to grab? Give an example site and state the content.

I don't think Telnet or ftp fits your requirements.
Try wget from http://gnuwin32.sourceforge.net/packages.html[^]

Use the Process class to invoke wget from c#

Thanks, but I am not supposed to use any third party tool, doesn't matters its GNU or GPL. I have to write all code on my own(as I mentioned using c# code) . :-)
