Я написал функцию в C # для загрузки файла, когда копирование в общую папку не работает.Я заметил, что любые загруженные файлы имеют размер примерно в 1,5-2 раза больше исходного и являются недопустимыми.Вот код:
public bool save_FTPUpload(FileInfo fi_attachment)
{
bool fileSaved = false;
string filename = fi_attachment.Name;
while (!fileSaved)
{
string file_ftpURI = string.Format("{0}/{1}", ftpURI, filename);
FtpWebRequest file_exist_request = (FtpWebRequest)FtpWebRequest.Create(file_ftpURI);
file_exist_request.Credentials = new NetworkCredential(ftp_user, ftp_pass);
file_exist_request.Method = WebRequestMethods.Ftp.GetFileSize;
try
{
FtpWebResponse response = (FtpWebResponse)file_exist_request.GetResponse();
}
catch (WebException ex)
{
FtpWebResponse response = (FtpWebResponse)ex.Response;
if (response.StatusCode ==
FtpStatusCode.ActionNotTakenFileUnavailable)
{
FtpWebRequest upload_request = (FtpWebRequest)FtpWebRequest.Create(file_ftpURI);
upload_request.Credentials = new NetworkCredential(ftp_user, ftp_pass);
upload_request.Method = WebRequestMethods.Ftp.UploadFile;
upload_request.UsePassive = true;
upload_request.UseBinary = true;
upload_request.KeepAlive = false;
StreamReader attachment = new StreamReader(fi_attachment.FullName);
byte[] attachmentData = Encoding.UTF8.GetBytes(attachment.ReadToEnd());
upload_request.ContentLength = attachmentData.Length;
//Stream upload_request_stream = upload_request.GetRequestStream();
using (Stream upload_request_stream = upload_request.GetRequestStream())
{
upload_request_stream.Write(attachmentData, 0, attachmentData.Length);
upload_request_stream.Close();
}
FtpWebResponse upload_response = (FtpWebResponse)upload_request.GetResponse();
fileSaved = true;
}
}
}
return fileSaved;
}
Любая помощь в выяснении этого будет отличной.
