Downloading File from FTP

Question

Hi I am Making a tool that download the files from ftp. i did that. but i have some doubts. for downloading the files i want to give the path with End file name. like follow. ftp://xxx.xxx.xxx.21//Direcotry/Sub_Directory1/Sub_Directory2/Sub_Directory3/Filename.zip But i want to download the file by giving the path like follow ftp://xxx.xxx.xxx.21//Direcotry /Sub_Directory1/Sub_Directory2/Sub_Directory3 because if there were more number of files in Sub_Directory3  then i want to give all the file names for download. to avoid that i asking this. i think it's possible. but i don't know how to do that. can any one guide me tho that. Thanks in Advance.

Please share the code to know which class you are using. I think using WebClient class will provide more command over this Check this link for reference http://stackoverflow.com/questions/11994486/c-sharp-webclient-stream-download-file-from-ftp-to-local-storage

@Amit. I found the solution. i didn't give the download file namein the local path string. While Error : ftpClient.DownloadFile(path localpath); Now : ftpClient.DownloadFile(path dirpath.ToString()+\ + directories[i].ToString()); my code will download all the files sub directories and the files inside the sub-directories. and also that maintain the Directory structure which is same like in FTP. use that amit. Thank You.

@Amit. This my new code. just modified the code which i had sent you in the morning in that code file downloded from ftp but in this code file was not downloading. i got a error in ftpClient.DownloadFile(path localpath); line. could not find the part of the path this is the error. it say's that the local path i snot exist. but i the localpath is correct. that's already exists. also that worked in the morning. but not now. i can't find the solution. what is the problem. txtftpaddress.Text = > path of the ftp file. try { FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(ftp://xxx.xxx.xxx.xx/ + txtftpaddress.Text); ftpRequest.Credentials = new NetworkCredential(txtusername.Text txtpassword.Text); ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory; FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse(); StreamReader streamReader = new StreamReader(response.GetResponseStream()); List directories = new List (); string line = streamReader.ReadLine(); while (!string.IsNullOrEmpty(line)) { directories.Add(line); line = streamReader.ReadLine(); } using (WebClient ftpClient = new WebClient()) { ftpClient.Credentials = new NetworkCredential(txtusername.Text txtpassword.Text); string[] filename = txtftpaddress.Text.Split('/'); Filename = filename[filename.Length - 1]; string dirpath = localpath; for (int k = 0; k { dirpath = (dirpath + \ + filename[k]).Replace(  ); RD.createdir(dirpath); } try { for (int i = 0; i { if (directories[i].Contains(.)) { string path = ftp://xxx.xxx.xxx.xx// + txtftpaddress.Text +/ + directories[i].ToString(); ftpClient.DownloadFile(path localpath); } else { string path = ftp://us-atl-ftp01.spi-global.com// + txtftpaddress.Text + / + directories[i].ToString(); string subdirpath = dirpath + \ + directories[i].ToString(); RD.createdir(subdirpath); //Create Directory string[] subdirectory = RD.Return(path txtusername.Text txtpassword.Text); // getting sub-directory list for (int j = 0; j { string subpath = directories[i] + / + subdirectory[j]; directories.Add(subpath); } } } } catch (WebException e) { String status = ((FtpWebResponse)e.Response).StatusDescription; MessageBox.Show(status.ToString()); } } streamReader.Close(); } catch (WebException l) { String status = ((FtpWebResponse)l.Response).StatusDescription; MessageBox.Show(status.ToString()); }

@Karthi Its quite difficult to understand what you are trying to achieve. I am quite sure that your code is not work properly. Do you want to list all the folders and files contains in your ftp path and download each files accordingly. Check the link for listing the files from ftp http://www.c-sharpcorner.com/UploadFile/9b86d4/how-to-list-all-files-directories-from-a-ftp-server-in-C-Sharp/ To download the files just you need to concatenate the files with your ftp domain name. Do let me know is that you are looking for.
