server side:
                    NetworkStream ns = cl.GetStream(); //cl is my
tcpClient for one connection with client

                    e.Save(stream, tt[1], encodeurs);    // stream is
a MemoryStream
                    stream.Position = 0;
                    byte[] buffer = new byte[stream.Length];
                    stream.Write(buffer , 0, buffer .Length);   //now
my picture is in buffer

                   System.IO.StreamWriter sw = new
System.IO.StreamWriter(ns);     //
                    sw.WriteLine(stream.Length.ToString());   // I
send first the picture's size
                    sw.Flush();
                    ns.Write(buffer , 0, buffer.Lenght);    //Send
picture

client side:

            stream = client.GetStream();
            streamReader = new System.IO.StreamReader(stream);

            string size = streamReader.ReadLine();  //Get picture size

            byte[] buffer = new byte[Convert.ToInt32(size)]; //create
buffer with good size
            int nRead = stream.Read(buffer, 0, buffer.Length);  //read
the picture
            System.IO.MemoryStream ImageDataStream = new
System.IO.MemoryStream();
            ImageDataStream.Read(buffer, 0, nRead );

           Image img = Image.FromStream(ImageDataStream );  Get the
picture from memoryStream

This method doesn't work good and is not stable.

Is it possible by an other method to skip to send the picture size?

What is the real and best method that works, never failed, to send
picture from webcam by socket in c#?
I'm sure it's possible to skip sending the size but I didn't find any
methods that works!

thanks a lot
