How do I set Filestream from an fileupload control? - asp.net

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!
