my problem consists in sending an image bytes over udp, I have an api made strictly to imitate tcp but work as udp too, all I want is to split the image into chunks and send each one to the server, the last one with a "what's left" length

Client Side (Transmitter)

using (var stream = new MemoryStream())

                {

                    Frame.Save(stream, ImageFormat.Png);



                    byte ImageBuffer = stream.ToArray();

                    byte SendBuffer = new byte[400];



                    Client.QuickMessage("SI", ImageBuffer.Length); // Start Image, buffer length



                    int lastPacketPos = 0;

                    for (int lastCounter = 0; lastCounter <= ImageBuffer.Length - 400; lastCounter += 400)

                    {

                        Buffer.BlockCopy(ImageBuffer, lastCounter, SendBuffer, 0, 400);

                        Client.SecureMessage("IP", SendBuffer, true); // Image Packet, buffer

                        lastPacketPos = lastCounter;



                        Thread.Sleep(1);

                    }



                    SendBuffer = new byte[ImageBuffer.Length - lastPacketPos];

                    Buffer.BlockCopy(ImageBuffer, lastPacketPos, SendBuffer, 0, ImageBuffer.Length - (lastPacketPos));

                    Client.SecureMessage("LP", SendBuffer, true); // Last Packet, buffer

                }

Server Side (Receiver)

byte ImageMemory;

    int bitCounter = 0;

    ShareScreenWindow ClientShareWindow = new ShareScreenWindow();

    private void Server_onReceivedData(string ClientName, string Message, object Obj)

    {

        if (Message == "SI")

        {

            ImageMemory = new byte[(int)Obj];

            Console.WriteLine("R " + (int)Obj);

            bitCounter = 0;

        }

        else if (Message == "IP")

        {

            Buffer.BlockCopy((byte)Obj, 0, ImageMemory, bitCounter, ((byte)Obj).Length);

            bitCounter += ((byte)Obj).Length;

            Console.WriteLine(bitCounter);

        }

        else if (Message == "LP")

        {

            Buffer.BlockCopy((byte)Obj, 0, ImageMemory, bitCounter, ((byte)Obj).Length);

            using (MemoryStream ImageStream = new MemoryStream(ImageMemory))

            {

                ClientShareWindow.ShareImage.Image = Image.FromStream(ImageStream);

                ImageStream.Dispose();



            }

        }

    }

Nothing works so far, I had various errors from count being bigger than the buffer size on server side, or drawing.dll error, please help!

Messages are being sent in order, that's not the problem
