The following code is intended to retrieve a file via FTP. However, I'm getting an error with it.
serverPath = "ftp://x.x.x.x/tmp/myfile.txt";
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverPath);
request.KeepAlive = true;
request.UsePassive = true;
request.UseBinary = true;
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential(username, password);
// Read the file from the server & write to destination
using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) // Error here
using (Stream responseStream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(responseStream))
using (StreamWriter destination = new StreamWriter(destinationFile))
{
destination.Write(reader.ReadToEnd());
destination.Flush();
}
The error is:
The remote server returned an error: (550) File unavailable (e.g., file not found, no access)
The file definitely does exist on the remote machine and I am able to perform this ftp manually (i.e. I have permissions). Can anyone tell me why I might be getting this error?
This paragraph from the FptWebRequest class reference might be of interest to you:
The URI may be relative or absolute. If the URI is of the form "ftp://contoso.com/%2fpath" (%2f is an escaped '/'), then the URI is absolute, and the current directory is /path. If, however, the URI is of the form "ftp://contoso.com/path", first the .NET Framework logs into the FTP server (using the user name and password set by the Credentials property), then the current directory is set to /path.
