file sending

[Vivek Vijayan]

m doin an applciation- file sending thru socket- i think its send as bytes.but wht funcitoon i can use to send it. do i need to save it to a temporary location to convert it to bytes can any one help me

This code was posted by me...

send bytes in a specific format, like first of all send a long value that is the size of file and then keep send file's data in bytes...and at receiver-end first read that long value and write those bytes direct to file... use Socket.Send() to send bytes...

no, .Net does itself...you can use either System.IO.File.ReadAllByte() if file size is smaller than 2GB or use FileStream have a look at these An Asynchronous Socket Server and Client[^] File Transfer using Socket Application in C#.Net 2[^]

I believe the function is called: System.IO.File.GetAllBytes() Or something like that. Granted, if it's a big file, you probably want to stream it a chunk at a time, using an algorithm kind of like this:

byte[] buffer = new byte[BUFFER_SIZE];
StreamReader sr = ...open the file...
while (!sr.EndOfStream)
{
int numBytes = sr.Read(buffer, 0);
yourNetworkStreamWriter.Write(buffer, 0, numBytes);
}

Yes. It will be send as several chunks of bytes.

Your message says you are just a beginner. So try with TcpListener and TcpClient classes. However, the best way to do network programming is to work with Socket class directly.

File.ReadAllBytes[^] will give you bytes of a file. I'd suggest to please avoid txtspeak[^] when you post messages. It is not readable. :)

Huh?! A file is already made of bytes. What conversion are you talking about? :confused:
