I have a problem, the problem is that I can upload ftp files, but the files I downoad do not have the ability to resume and a lot of file files, because there is a large file larger than 500 MB of files, I can’t download files constantly, because I get disconnect and start the download from the beginning, I wanted my code to resume working if it disconnects
The code I use
public string[] GetFileList() { string[] downloadFiles; StringBuilder result = new StringBuilder(); FtpWebRequest reqFTP; try { reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/")); reqFTP.UseBinary = true; reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword); reqFTP.Method = WebRequestMethods.Ftp.ListDirectory; WebResponse response = reqFTP.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); //MessageBox.Show(reader.ReadToEnd()); string line = reader.ReadLine(); while (line != null) { result.Append(line); result.Append("\n"); line = reader.ReadLine(); } result.Remove(result.ToString().LastIndexOf('\n'), 1); reader.Close(); response.Close(); //MessageBox.Show(response.StatusDescription); return result.ToString().Split('\n'); } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); downloadFiles = null; return downloadFiles; } } private void Download(string filePath, string fileName) { FtpWebRequest reqFTP; try { //filePath = <<The full path where the file is to be created.>>, //fileName = <<Name of the file to be created(Need not be the name of the file on FTP server).>> FileStream outputStream = new FileStream(filePath + "\\" + fileName, FileMode.Create); reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + fileName)); reqFTP.Method = WebRequestMethods.Ftp.DownloadFile; reqFTP.UseBinary = true; reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword); FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse(); Stream ftpStream = response.GetResponseStream(); long cl = response.ContentLength; int bufferSize = 2048; int readCount; byte[] buffer = new byte[bufferSize]; readCount = ftpStream.Read(buffer, 0, bufferSize); while (readCount > 0) { outputStream.Write(buffer, 0, readCount); readCount = ftpStream.Read(buffer, 0, bufferSize); } ftpStream.Close(); outputStream.Close(); response.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message); } }
private void btnDownload_Click (object sender, EventArgs e) {
FolderBrowserDialog fldDlg = new FolderBrowserDialog(); if (txtUpload.Text.Trim().Length > 0) { if (fldDlg.ShowDialog() == DialogResult.OK) { Download(fldDlg.SelectedPath, txtUpload.Text.Trim()); } } else { MessageBox.Show("Please enter the File name to download"); } }
I need a resume mechanism in my code,
would be an excellent assessment if someone could help me,
Thanks in advance
