Hi If you want user to select file location to save use this code : private void Download(string filePath string fileName) { FtpWebRequest reqFTP; try { 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); ftpStream.Close(); response.Close(); this.Response.ClearContent(); this.Response.Clear(); this.Response.ContentType = APPLICATION/OCTET-STREAM; String Header = Attachment; Filename= + fileName; this.Response.AppendHeader(Content-Disposition Header); this.Response.BinaryWrite(buffer); } catch (Exception ex) { } this.Response.End(); // This line is very important }

Hi You can try this code : private void Download(string filePath string fileName) { FtpWebRequest reqFTP; try { //filePath = //file is to be created. the>> //fileName = //name on FTP server. name name()>> 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) { } } For more details check this aticles : http://www.codeproject.com/Articles/17202/Simple-FTP-demo-application-using-C-Net http://cybarlab.com/download-upload-files-from-ftp-server-in-c-sharp https://satishratnaparkhi.wordpress.com/2013/10/08/how-to-download-and-upload-files-with-ftp-using-asp-net/
