How to append bytes to first of stream in sending file by NetworkStream

Question

i want append 8 bytes of my info to first of stream in sending file. i use NetworkStream and my code is this:

        Stream Fs = File.OpenRead("filepath");
        Byte[] buffer = new Byte[Fs.Length];
        Fs.Read(buffer, 0, buffer.Length);
        NetworkStream serverStream = clientSocket.GetStream();
        serverStream.Write(buffer, 0, buffer.Length);
        serverStream.Close();

How can i add my strings? thanks

Simply add an extra Write call before the one you've got. Write the 8 bytes first and then write the file contents.

By the way, if you're going to read the entire file into a byte array then don't use those first three lines (which fail to close the FileStream by the way). Just call File.ReadAllBytes and do it all in one line.
