How to tell if FTP download successful?

[Tim Cowan]

Hi,

I am using this code to download files on VS 2005. It downloads the file but
waits until the timeout (which is why it is so short) to add the last 4
bytes or so. It always returns a WebException which most of the time is just
feedback from the FTP server, so how do I tell if the download was
successful/complete or not?

public void DownloadFile(st ring fileName, string mfgrId)
{
try
{
string destinationFile = @"C:\Program Files\MM\" + fileName;
FileInfo file = new FileInfo(destin ationFile);
FileStream localfileStream ;
FtpWebRequest request = WebRequest.Crea te("ftp://" + hostname + downloadDir
+ fileName) as FtpWebRequest;
request.Method = WebRequestMetho ds.Ftp.Download File;
request.Timeout = 5000; //five seconds
if (file.Exists)
{
request.Content Offset = file.Length;
localfileStream = new FileStream(dest inationFile, FileMode.Append ,
FileAccess.Writ e);
}
else
{
localfileStream = new FileStream(dest inationFile, FileMode.Create ,
FileAccess.Writ e);
}
WebResponse response = request.GetResp onse();
Stream responseStream = response.GetRes ponseStream();
byte[] buffer = new byte[1024];
int bytesRead = responseStream. Read(buffer, 0, 1024);
while (bytesRead != 0)
{
localfileStream .Write(buffer, 0, bytesRead);
bytesRead = responseStream. Read(buffer, 0, 1024);
}
localfileStream .Close();
responseStream. Close();
ErrorReporter.L ogableError(fil eName + " downloaded successfully",
ErrorReporter.E rrorTypes.DDS);
}
finally
{
}
}
