Saya ingin membuat sebuah program yang memeriksa alamat ip terus menerus.
saya punya source code yang memeriksa alamat ip dan port, seperti ini

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Net;

using System.Net.Sockets;

using System.Threading;

using System.IO;

 

namespace WinNetworkIOCS {

 public partial class Form1 : Form {

 public Form1() {

 InitializeComponent();

 }

 

 private void ConnectButton_Click(object sender, EventArgs e) {

 DisableFields();

 DoNetworkingConnection();

 }

 

 private void DisableFields() {

 PortBox.Enabled = false;

 IPAddressBox.Enabled = false;

 SendMessageBox.Enabled = false;

 ConnectButton.Enabled = false;

 }

 

 private void EnableFields() {

 PortBox.Enabled = true;

 IPAddressBox.Enabled = true;

 SendMessageBox.Enabled = true;

 ConnectButton.Enabled = true;

 }

 

 private void WriteToStatusBar(string Message) {

 //EnableFields();

 ThreadHelperClass.SetText(this, lblStatus, Message);

 }

 

 private void DoNetworkingConnection() {

 Thread MyThread = null;

 

 try {

 ThreadStart ThreadMethod = new ThreadStart(ConnectTo);

 MyThread = new Thread(ThreadMethod);

 } catch (Exception e) {

 WriteToStatusBar("Failed to create thread with error: " + e.Message);

 return;

 }

 

 try {

 MyThread.Start();

 } catch (Exception e) {

 WriteToStatusBar("The thread failed to start with error: " + e.Message);

 }

 }

 

 private void ConnectTo() {

 string ServerName = this.IPAddressBox.Text;

 int Port = System.Convert.ToInt32(this.PortBox.Text);

 

 WriteToStatusBar("IP Address: " + ServerName + "Port: " + Port);

 Socket ClientSocket = null;

 

 try {

 // Let's connect to a listening server

 try {

 ClientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);

 WriteToStatusBar("Socket is OK...");

 } catch (Exception e) {

 throw new Exception("Failed to create client Socket: " + e.Message);

 }

 

 IPEndPoint ServerEndPoint = new IPEndPoint(IPAddress.Parse(ServerName), Convert.ToInt16(Port));

 

 try {

 ClientSocket.Connect(ServerEndPoint);

 WriteToStatusBar("Connect() is OK...");

 } catch (Exception e) {

 throw new Exception("Failed to connect client Socket: " + e.Message);

 }

 } catch (Exception e) {

 WriteToStatusBar(e.Message);

 ClientSocket.Close();

 return;

 }

 

 // Let's create a network stream to communicate over the connected Socket.

 NetworkStream ClientNetworkStream = null;

 

 try {

 try {

 // Setup a network stream on the client Socket

 ClientNetworkStream = new NetworkStream(ClientSocket, true);

 WriteToStatusBar("Instantiating NetworkStream...");

 } catch (Exception e) {

 // We have to close the client socket here because the network

 // stream did not take ownership of the socket.

 ClientSocket.Close();

 throw new Exception("Failed to create a NetworkStream with error: " + e.Message);

 }

 

 StreamWriter ClientNetworkStreamWriter = null;

 

 try {

 // Setup a Stream Writer

 ClientNetworkStreamWriter = new StreamWriter(ClientNetworkStream);

 WriteToStatusBar("Setting up StreamWriter...");

 } catch (Exception e) {

 ClientNetworkStream.Close();

 throw new Exception("Failed to create a StreamWriter with error: " + e.Message);

 }

 

 try {

 ClientNetworkStreamWriter.Write(this.SendMessageBox.Text.ToString());

 ClientNetworkStreamWriter.Flush();

 WriteToStatusBar("We wrote " + this.SendMessageBox.Text.Length.ToString() + " character(s) to the server.");

 } catch (Exception e) {

 throw new Exception("Failed to write to client NetworkStream with error: " + e.Message);

 }

 } catch (Exception e) {

 WriteToStatusBar(e.Message);

 } finally {

 // Close the network stream once everything is done

 ClientNetworkStream.Close();

 }

 }

 

 delegate void SetTextCallback(string text);

 }

}

tetapi tidak memeriksa alamat IP dan port terus menerus, secara realtime.
Apa yang harus saya tambahkan di coding saya.
