FTP

I am using ftplib for uploading files on ftp server using following code

FtpConnection ftp = new FtpConnection(serverip, ftpuser, ftppassword);
ftp.Open();
ftp.Login();
ftp.SetCurrentDirectory("domain/wwwroot");

void CreateDirOnFtp(string sDir, FtpConnection ftp)
            {
                try
                {
                    foreach (string f in Directory.GetFiles(sDir))
                    {
                        Uri uri = new Uri(f);
                        ftp.PutFile(f, System.IO.Path.GetFileName(uri.LocalPath));
                    }

                    foreach (string d in Directory.GetDirectories(sDir))
                    {
                        string dirname = new DirectoryInfo(d).Name;

                        if (!ftp.DirectoryExists(dirname))
                        {
                            ftp.CreateDirectory(dirname);
                        }

                        ftp.SetCurrentDirectory(dirname);
                        CreateDirOnFtp(d, ftp);
                    }
                }
                catch (System.Exception e)
                {
                }

            }

But this code is not iterating through all directories so missing some directories and files on ftp server.

so i decided to upload zip file on ftp and extract it on ftp server but I cant find any way to extract file which exist on ftp server.

How can i do this? Or any other better way to upload mutiple directories and file on ftp server
