C#__how can I receive packet from ethernet in the form of byte[] using Pcap.net

[rkt_167]

hi all,
i am building a GUI for packet capturing through Ethernet interface.
i am using this code for selecting interface.

Ques: The packet which i am getting how can i pass it in the form of byte array. pls give syntax..
actually i want to pass the received packet in the form of bytes through a function for its further processing.

// Retrieve the device list from the local machine
            IList<LivePacketDevice> allDevices = LivePacketDevice.AllLocalMachine;

            if (allDevices.Count == 0)
            {
                MessageBox.Show("Select an Interface to capture the packets.", "**ERROR**",
                   MessageBoxButtons.OK, MessageBoxIcon.Error);
                return;
            }

            // Print the list
            for (int i = 0; i != allDevices.Count; ++i)
            {
                LivePacketDevice device = allDevices[i];
                cmbInterfaces.Items.Add(device.Name);
                //Console.Write((i + 1) + ". " + device.Name);
                if (device.Description != null)
                    cmbInterfaces.Items.Add(device.Description);
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            // Retrieve the device list from the local machine
            IList<LivePacketDevice> allDevices = LivePacketDevice.AllLocalMachine;
            int deviceIndex = 0;
            while (deviceIndex == 0)
            {
                //Console.WriteLine("Enter the interface number (1-" + allDevices.Count + "):");
                string deviceIndexString = box.Text;
                if (!int.TryParse(deviceIndexString, out deviceIndex) ||
                    deviceIndex < 1 || deviceIndex > allDevices.Count)
                {
                    deviceIndex = 0;
                }
            };

            // Take the selected adapter
            PacketDevice selectedDevice = allDevices[deviceIndex - 1];

            // Open the device
            using (PacketCommunicator communicator =
                selectedDevice.Open(65536,                                  // portion of the packet to capture
                // 65536 guarantees that the whole packet will be captured on all the link layers
                                    PacketDeviceOpenAttributes.Promiscuous, // promiscuous mode
                                    1000))                                  // read timeout
            {

                    switch (result)
                    {
                        case PacketCommunicatorReceiveResult.Timeout:
