Hi There,

I have created a windows .net service. which is used to move the files from (uri/fiolder1/filename) to (uri/fiolder1/Archive/filename) of ftp. My code is as follows:

C#

FtpWebRequest Wr = null;
NetworkCredential User = null;
try
{
  WriteLog("Processing Archiving on FTP: File Name: " + File);
  User = new NetworkCredential(FTPUser, FTPPass);
  Wr = (FtpWebRequest)FtpWebRequest.Create(FTPUri + File);
  Wr.UseBinary = true;
  Wr.KeepAlive = false;
  Wr.Method = WebRequestMethods.Ftp.Rename;
  Wr.Credentials = User;
  //Wr.RenameTo = "Archive/"  + DateTime.Now.AddHours(-11).ToString("dd-MM-yyyy_HH_mm_ss") +"_" +File;
  Wr.RenameTo = "Archive/" + DateTime.Now.ToString("dd-MM-yyyy_HH_mm_ss") + "_" + File;
  FtpWebResponse back = (FtpWebResponse)Wr.GetResponse();
  //bool Success = back.StatusCode == FtpStatusCode.CommandOK || back.StatusCode == FtpStatusCode.FileActionOK;
  back.Close();
  Wr = null;
  User = null;
  
  return true;
}
catch (Exception ex)
{
  WriteLog("Err at MoveFileToArchiveOnFTP :>" + ex.Message);
  return false;
}

It is working fine but some time it throws an error:The remote server returned an error: (450) File unavailable (e.g., file busy).

So please help me to resolve this error ASAP.

C#

//strFTPIP is address of FTP Server and strFile is Filename
var ftpWebRequest = (FtpWebRequest)FtpWebRequest.Create(strFTPIP + strFile);

ftpWebRequest.KeepAlive = false;
ftpWebRequest.UseBinary = true;

//strFTPuserName is username of ftp server and strFTPPassword is password of ftp server
ftpWebRequest.Credentials = new NetworkCredential(strFTPuserName, strFTPPassword);
ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;

//filepath is path of the file in local server
using (var inputStream = File.OpenRead(filepath))
using (var outputStream = ftpWebRequest.GetRequestStream())
{
        var buffer = new byte[4096];
        int totalReadBytesCount = 0;
        int readBytesCount;
        while ((readBytesCount = inputStream.Read(buffer, 0, buffer.Length)) > 0)
        {
                outputStream.Write(buffer, 0, readBytesCount);
                totalReadBytesCount += readBytesCount;
                var progress = totalReadBytesCount * 100.0 / inputStream.Length;
        }
}

ftpWebRequest.Abort();
