Image.FromStream using networkStream

Question

I'm trying to use the method FromStream of the class Image to set an image received by a tcp connection using a network stream. Here there are the two sides code:

Server:

TcpListener server = new TcpListener(IPAddress.Any, 34567);
server.Start();

TcpClient client = server.AcceptTcpClient();
byte[] buffer = new byte[256];

int n = 0;
Console.WriteLine("{0}, {1}", Encoding.ASCII.GetString(buffer, 0, n), client.Client.RemoteEndPoint);
byte[] img = File.ReadAllBytes(@"C:\Users\Luca\Desktop\video grest\8599929-nessun-segnale.jpg");
client.Client.Send(img);

Client:

TcpClient tcp = new TcpClient("127.0.0.1", 34567);
NetworkStream stream = tcp.GetStream();
MessageBox.Show("fatto");
pictureBox1.Image = Image.FromStream(stream);

The problem is that the client program stops on the last instruction and it doesn't go forward, and if close the server (even 30 minutes later) it says the connection was closed but the picturebox doesn't show anything... Why?

Thanks in advance.

Answer 1

I think that your client code

pictureBox1.Image = Image.FromStream(stream);

is expecting for the stream to be ended before processing the image.

So you should close the socket server-side using:

client.Close();

just after:

client.Client.Send(img);
