Question

Following is the code snippet to copy txt file from a location to a ftp path:

WebRequest WRequest = WebRequest.Create(FtpPath + OriginalfileName);
WRequest.Method = WebRequestMethods.Ftp.UploadFile;
WRequest.Credentials = new NetworkCredential("myusername", "FtpPassword");
FileStream stream = File.OpenRead(OriginalFilePath);
byte[] buffer = new byte[stream.Length];
Stream RStream = WRequest.GetRequestStream();
RStream.Write(buffer, 0, buffer.Length);
RStream.Close();

But the copied file at ftp destination is always empty. Why?

Answer 1

You’re not populating the buffer with the contents of the file. You’re just setting the length in the following line of code:

byte[] buffer = new byte[stream.Length];

And you’re not filling it with the contents of the file anywhere else, either, so you’re just sending empty data to the FTP server. The bytes may have a certain length, but it’s all empty bytes.
