مشکل در اضافه کردن کنترل ها در سی شارپ

سلام
من یک برنامه کنسول اپلیکیشن دارم که میخوام تبدیل کنم به ویندوز اپلیکیشن و خروجی داده ها رو در لیست باکس بهم نشون یده ولی یک مشکلی دارم . اینکه در private static void DispatcherHandler که می خوام به جای console.write بگم در لیست باکس نشون بده اما اصلا هیچ کنترلی رو نمیشناسه.
این برنامه کنسول اپلیکیشن که درست کار میکنه:

namespace ConsoleApplication3_read_from_file

{

    class Program

    {

        static void Main(string[] args)

        {

              if (args.Length == 0)

            {

                args = new string[] { @"C:\Users\Only God Remains\Desktop\naja prject\HTTP.pcap" };

            }





            // Check command line

            if (args.Length != 1)

            {

                Console.WriteLine("usage: " + Environment.GetCommandLineArgs()[0] + " <filename>");

                return;

            }





            // Create the offline device

            OfflinePacketDevice selectedDevice = new OfflinePacketDevice(args[0]);





            // Open the capture file

            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

            {

                // Read and dispatch packets until EOF is reached

                communicator.ReceivePackets(0, DispatcherHandler);

            }

            Console.ReadKey();

        }





        private static void DispatcherHandler(Packet packet)

        {

            // print packet timestamp and packet length

            Console.WriteLine(packet.Timestamp.ToString("yyyy-MM-dd hh:mm:ss.fff") + " length:" + packet.Length);

            Console.Write("Source: " + packet.IpV4.Source.ToString());

            Console.WriteLine("\tDestination: " + packet.IpV4.Destination.ToString());





            //object obj = packet.IpV4.Tcp.Http.Body;

            //ILayer lay = packet.IpV4.Tcp.Http.ExtractLayer();

















            // Print the packet

            //const int LineLength = 64;

            //for (int i = 0; i != packet.Length; ++i)

            //{

            //    Console.Write((packet[i]).ToString("X2"));

            //    if ((i + 1) % LineLength == 0)

            //      Console.WriteLine();

            //}





            Console.WriteLine();

            Console.WriteLine();

        }

        }

    }

برنامه ویندوز اپلیکیشن که خروجی نشون نمیده:

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }





        private void btnBrowseFile_Click(object sender, EventArgs e)

        {

            OpenFileDialog ofd = new OpenFileDialog();

            ofd.Filter = "*|*";

            if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)

            {

                txtFilePath.Text = ofd.FileName;

            }

        }





        private void button1_Click(object sender, EventArgs e)

        {

            OfflinePacketDevice selectedDevice = new OfflinePacketDevice(txtFilePath.Text);

            // OfflinePacketDevice selectedDevice = new OfflinePacketDevice(@"C:\Users\Only God Remains\Desktop\naja prject\HTTP.pcap");





            // Open the capture file

            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

            {

                // Read and dispatch packets until EOF is reached

                communicator.ReceivePackets(0, DispatcherHandler);





            }

        }





        //public ListBox lb = new ListBox();

        private static void DispatcherHandler(Packet packet)

        {

            // print packet timestamp and packet length





            //Console.WriteLine(packet.Timestamp.ToString("yyyy-MM-dd hh:mm:ss.fff") + " length:" + packet.Length);

            //Console.Write("Source: " + packet.IpV4.Source.ToString());

            //Console.WriteLine("\tDestination: " + packet.IpV4.Destination.ToString());













            ListBox lb = new ListBox();





            lb.Items.Add("Source: " + packet.IpV4.Source.ToString());

            lb.Items.Add("\tDestination: " + packet.IpV4.Destination.ToString());

















            //object obj = packet.IpV4.Tcp.Http.Body;

            //ILayer lay = packet.IpV4.Tcp.Http.ExtractLayer();





            // Print the packet

            //const int LineLength = 64;

            //for (int i = 0; i != packet.Length; ++i)

            //{

            //    Console.Write((packet[i]).ToString("X2"));

            //    if ((i + 1) % LineLength == 0)

            //      Console.WriteLine();

            //}

میشه لطف کنید بگید مشکل چیه؟

برا دسترسی به شی های فرم نباید تابع از نوع static باشه
