I've read through and knew that we can actually enable the ssl. I did not intend to purchase any third party components but would prefer to use the existing. Now, I would like to modified the program to ftps method. If you want to download all files from a remote folder, seeĬ# Download all files and subdirectories through FTP.Hi, I have developed a ftp upload/download program using vb.net and it's working well. While ((read = fileStream.Read(buffer, 0, buffer.Length)) > 0)Ĭonsole.WriteLine('Uploaded bytes', fileStream.Position) įor GUI progress (WinForms ProgressBar), see:įtpWebRequest FTP download with ProgressBar If you need to monitor an upload progress, you have to copy the contents by chunks yourself: FtpWebRequest request = Using (Stream fileStream = (Stream ftpStream = request.GetRequestStream()) Request.Credentials = new NetworkCredential('username', 'password') Easy way is to just copy a FileStream to FTP stream using Stream.CopyTo: FtpWebRequest request = '', you need a greater control, that WebClient does not offer (like TLS/SSL encryption, ascii/text transfer mode, transfer resuming, etc), use FtpWebRequest. NET framework is using WebClient.UploadFile: WebClient client = new WebClient() Ĭlient.Credentials = new NetworkCredential('username', 'password')

The most trivial way to upload a binary file to an FTP server using.

except when I try to unzip the downloaded ZIP file I get an invalid ZIP file. ReadCount = responseStream.Read(buffer, 0, bufferSize) Ģ) Everything seems to work. Using (FileStream writer = new FileStream(localFilename, FileMode.Create)) Using (StreamReader reader = new StreamReader(responseStream)) Using (Stream responseStream = response.GetResponseStream()) Using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) This seems to work, in that I get a file on the server of the right size.ġ) How do I stream it, rather than load it into memory first? I will be uploading very large files.Īnd for downloading I have using (WebClient client = new WebClient())įtpWebRequest request = (FtpWebRequest)WebRequest.Create(remoteFile) Response = (FtpWebResponse)request.GetResponse() RequestStream.Write(fileContents, 0, fileContents.Length) Using (Stream requestStream = request.GetRequestStream())

Request.ContentLength = fileContents.Length Using (StreamReader sourceStream = new StreamReader(LocalFilePath))įileContents = (sourceStream.ReadToEnd()) Request.Credentials = new NetworkCredential(MyLogin, MyPassword)

I am trying to upload and then download a ZIP file to (my) server.įor uploading I have using (WebClient client = new WebClient())įtpWebRequest request = (FtpWebRequest)WebRequest.Create(MyUrl)

Ftp client download method .net
