Question

Now I know how to copy files from one directory to another, this is really simple.

But now I need to do the same with files from FTP server. Can you give me some example how to get file from FTP while changing its name?

Answer 1

Take a look at How to: Download Files with FTP or downloading all files in directory ftp and c#

 // Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
            request.Method = WebRequestMethods.Ftp.DownloadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential ("anonymous","[e-mail]");

            FtpWebResponse response = (FtpWebResponse)request.GetResponse();

            Stream responseStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(responseStream);
            Console.WriteLine(reader.ReadToEnd());

            Console.WriteLine("Download Complete, status {0}", response.StatusDescription);

            reader.Close();
            reader.Dispose();
            response.Close();
