Question

This is my code and I can’t seem to get the file I have in my FileUploadCotrol into the FILESTREAM.

 // The buffer size is set to 2kb
int buffLength = 2048;
byte[] buff = new byte[buffLength];
int contentLen;

// Opens a file stream (System.IO.FileStream) to read the file to be uploaded
FileStream fs = fileInf.OpenRead();

try
{
    // Stream to which the file to be upload is written
    Stream strm = reqFTP.GetRequestStream();

    // Read from the file stream 2kb at a time
    contentLen = fs.Read(buff, 0, buffLength);

    // Till Stream content ends
    while (contentLen != 0)
    {
        // Write Content from the file stream to the FTP Upload Stream
        strm.Write(buff, 0, contentLen);
        contentLen = fs.Read(buff, 0, buffLength);
    }

    // Close the file stream and the Request Stream
    strm.Close();
    fs.Close();
}

It seems the I should be using the Fileupload control to do the from my website, yet it seams strange that the control creates a stream and not a filestream. Yes I am FTPing a file.

Here is a sample method that takes the two types we are targeting, FileInfo and FtpWebRequest, as arguments and streams data between them. I believe this will work.

    void UploadFileToFtp(FileInfo file, FtpWebRequest req)
    {
        int buffLength = 2048;

        using (var reader = new BinaryReader(file.OpenRead()))
        {
            using (var writer = new BinaryWriter(req.GetRequestStream()))
            {
                while (reader.PeekChar() > 0) writer.Write(reader.ReadBytes(buffLength));
            }
        }
    }

Hope this helps!
