Hi Al,

After opening the connection to 21 you will have to write code to send
ftp commands (USER,PWD BY etc).
And your class will have the construcotr for taking username password
and stuff..

Or use 3rd party components.

check this out

http://www.google.com/search?sourceid=gmail&q=ftp%20client%20in%20.net

TcpClient first argument is not an URL, but just a host name.

.NET has built in FTP support since .NET 2.0 - code snippet:

        public static void Upload(string localfile, string ftpurl, bool
bin)
        {
            FtpWebRequest req = (FtpWebRequest)WebRequest.Create(ftpurl);
            req.Method = WebRequestMethods.Ftp.UploadFile;
            req.UseBinary = bin;
            if(bin)
            {
                Stream instm = new FileStream(localfile, FileMode.Open,
FileAccess.Read);
                Stream outstm = req.GetRequestStream();
                byte[] b = new byte[10000];
                int n;
                while((n = instm.Read(b, 0, b.Length)) > 0)
                {
                    outstm.Write(b, 0, n);
                }
                instm.Close();
                outstm.Close();
            }
            else
            {
                StreamReader sr = new StreamReader(localfile);
                StreamWriter sw = new StreamWriter(req.GetRequestStream());
                string line;
                while((line = sr.ReadLine()) != null)
                {
                    sw.WriteLine(line);
                }
                sr.Close();
                sw.Close();
            }
            FtpWebResponse resp = (FtpWebResponse)req.GetResponse();
            Console.WriteLine(resp.StatusCode);
        }

If you reall want to implement a FTP client using TcpClient, then
look at http://www.vajhoej.dk/arne/eksperten/div_2007_03/xftp.cs !
