Question

Does .NET (C#) have built in libraries for FTP? I don’t need anything crazy… very simple.

I need to:

1. FTP into an account
2. Detect if the connection was refused
3. Obtain a text file
4. Delete the text file

What’s the easiest way to do this?

Answer 1

Use the FtpWebRequest class, or the plain old WebClient class.

FTP into an account and retrieve a file:

WebClient request = new WebClient(); request.Credentials =      new NetworkCredential('anonymous', '[e-mail]'); try  {     // serverUri here uses the FTP scheme ('ftp://').     byte[] newFileData = request.DownloadData(serverUri.ToString());     string fileString = Encoding.UTF8.GetString(newFileData); } catch (WebException ex) {     // Detect and handle login failures etc here } 

Delete the file:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri); request.Method = WebRequestMethods.Ftp.DeleteFile; FtpWebResponse response = (FtpWebResponse)request.GetResponse(); Console.WriteLine('Delete status: {0}', response.StatusDescription);   response.Close();
