Using .NET 2.0, how do I FTP to the server, get the file and delete the file?

Question

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

I need:

• FTP to account
• Detect if connection was rejected
• Get text file
• Delete text file

What is the easiest way to do this?

Answer 1

Use the FtpWebRequest class or the plain old WebClient .

FTP to your account and get the 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 a 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();
