File Download, Upload, Delete in FTP Location using C# About If you have thesedifficulties ads with FTP File operations, you are at the right place. I am going to present some self explanatory code snippets in C# to accomplish FTP FILE operations like downloading, uploading and deleting.

using System.Net;

First of all, this directive is mandatory for FTP Operations. File Download From FTP:

string localPath = @"G:\FTPTrialLocalPath\"; string fileName = "arahimkhan.txt"; FtpWebRequest requestFileDownload = (FtpWebRequest)WebRequest.Create("ftp://localhost/Source/" requestFileDownload.Credentials = new NetworkCredential("khanrahim", "arkhan22"); requestFileDownload.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse responseFileDownload = (FtpWebResponse)requestFileDownload.GetResponse(); Stream responseStream = responseFileDownload.GetResponseStream(); FileStream writeStream = new FileStream(localPath + fileName, FileMode.Create); int Length = 2048; Byte[] buffer = new Byte[Length]; int bytesRead = responseStream.Read(buffer, 0, Length); while (bytesRead > 0) { writeStream.Write(buffer, 0, bytesRead); bytesRead = responseStream.Read(buffer, 0, Length); } responseStream.Close(); writeStream.Close(); requestFileDownload = null; responseFileDownload = null;

File Upload to FTP:

string localPath = @"G:\FTPTrialLocalPath\"; string fileName = "arahimkhan.txt";

FtpWebRequest requestFTPUploader = (FtpWebRequest)WebRequest.Create("ftp://127.0.0.1/Destinatio requestFTPUploader.Credentials = new NetworkCredential("khanrahim", "arkhan22"); requestFTPUploader.Method = WebRequestMethods.Ftp.UploadFile; FileInfo fileInfo = new FileInfo(localPath + fileName); FileStream fileStream = fileInfo.OpenRead(); int bufferLength = 2048; byte[] buffer = new byte[bufferLength]; Stream uploadStream = requestFTPUploader.GetRequestStream(); int contentLength = fileStream.Read(buffer, 0, bufferLength); while (contentLength != 0) { uploadStream.Write(buffer, 0, contentLength); contentLength = fileStream.Read(buffer, 0, bufferLength); } uploadStream.Close(); fileStream.Close(); requestFTPUploader = null;

File Delete From FTP:

string fileName = "arahimkhan.txt"; FtpWebRequest requestFileDelete = (FtpWebRequest)WebRequest.Create("ftp://localhost/Source/" + requestFileDelete.Credentials = new NetworkCredential("khanrahim", "arkhan22"); requestFileDelete.Method = WebRequestMethods.Ftp.DeleteFile; FtpWebResponse responseFileDelete = (FtpWebResponse)requestFileDelete.GetResponse();

Retrieve File List from FTP Directory:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://localhost/Source"); request.Credentials = new NetworkCredential("khanrahim", "arkhan22"); request.Method = WebRequestMethods.Ftp.ListDirectory; StreamReader streamReader = new StreamReader(request.GetResponse().GetResponseStream()); string fileName = streamReader.ReadLine(); while (fileName != null) { Console.Writeline(fileName ); fileName = streamReader.ReadLine();

} request = null; streamReader = null;

using System.IO;

You have to use this directive for Local File Operation. Retrieve File List from Local Directory:

string localPath = @"G:\FTPTrialLocalPath\"; string[] files = Directory.GetFiles(localPath); foreach (string filepath in files) { string fileName = Path.GetFileName(filepath); Console.WriteLine(fileName); } You can download source code.

Ian September 13th, 2010 REPLY QUOTE Rahim -I mostly need to use your upload code snippet however I am not clear for my requirement how to put pieces together. Your upload example shows uploading a single file, and my requirement is for uploading multiple files. So my requirement is like this: 1. have a C# FTP program that can run una ended from a task scheduler to upload all files in a

directory/sub directories on my local machine to a remote ftp server in a secure datacenter. The data center uses SSL (VeriSign). 2. Provide connection and session logging capability for troubleshooting problems. 3. Email via SMTP after uploads are completed/or failed after 3 a empts, connection and session logs to specified email address. 4. If possible -Username and password should not be hard coded in program, or contained in plain text configuration file. Note: we have MS: Windows 2003 Server, Active Directory, IIS, and SQL Server available in our environment, and use SSL from VeriSign . Can this be accomplished? Or is the only way to do this, is to hard code username and password in program and specify “EnableSsl to true” Can you please help. I am new to C#. Thanks kindly -Ian 2.

A Rahim Khan September 14th, 2010 REPLY QUOTE hi lan following code snippet will list file names from a local folder. ********************** string localPath = @”G:\FTPTrialLocalPath\”; string[] files = Directory.GetFiles(localPath); foreach (string filepath in files) { string fileName = Path.GetFileName(filepath); Console.WriteLine(fileName); // Here you can use file upload code for each filename } *********************** hope this will help you. Thanks

FtpWebResponse response = (FtpWebResponse)request.GetResponse(); } 4.

A Rahim Khan December 21st, 2010 REPLY QUOTE ma hew most probably, request can’t locate the file. The code snippet is ok and should work. you need to confirm that the file is in ftp location. Ma hew December 21st, 2010 REPLY QUOTE Yeah I figured it out, i set the default location for the FTP account to the wrong directory. I almost have a working FTP client now, I can upload, download, delete any file I want, but I cannot figure out how to display the directory you are currently viewing when you retrieve a file list. Ma hew December 21st, 2010 REPLY QUOTE Never mind, I have figured out a workaround, thank you for your help, I am not much of a programmer, but thanks to you I have my own FTP program

Keith Miller January 24th, 2012 REPLY QUOTE Some good general sample code. I like the fact the upload code breaks the upload into 2KB chunks, which some other sample code on the web fails to consider, and corresponding user comments say that the other code fails for larger files (no wonder). I have adapted this code into my own library and added test cases that test folder creation, file upload and file delete. I still need to figure out folder delete, but that is the last piece of the puzzle for me. Thanks to this post it has been a very short exercise for me to implement my own version. I’d like to offer anyone who reads this thread/post a free copy of WinReminders (just e-mail us; sales or support at WinReminders dot com) and we’ll be happy to oblige. This is in recognition of this useful sample post by Rahim.

A Rahim Khan February 10th, 2012 REPLY QUOTE the path you mentioned is not a ftp path. just move the file as if you move the file in a directory in same computer. google for C# code to move a file and use it with shared directory. moreover u will required write permission to copy files in that directory. hope now you can solve your problem. 15.

Nixa Testa July 10th, 2012 REPLY QUOTE Thank You, Rahim. I first used the example code from the MSDN library and was about to freak out because the files where always corrupted after up- or download. Following Your samples everything works well from the first time. It is incredible how the lousy lamers at Microsoft are not even able to provide a working sample for their own components.
