Reverse communication -Capturing data in ip

Hi Joshi,

Thanks for quick reply. Below is the code.

Error while i am trying to capture the data "Object reference not set to an instance"



using System;
using System.Collections.Generic;
using System.Net.Sockets;
using System.Text;
using System.IO;
using Microsoft.Win32;
using System.Reflection;
using System.Runtime.InteropServices;

namespace Client
{
class Program
{
public static bool IsConnected;
public static NetworkStream Receiver;

public static NetworkStream Writer;

static void Main(string[] args)
{

Connect_to_Server();
Read_Command();

}

public static void Connect_to_Server()
{

TcpClient Connector = new TcpClient();

GetConnection:

Console.WriteLine("Enter server IP :");

string IP = Console.ReadLine();

try

{
Connector.Connect(IP, 2000);

IsConnected = true;

Writer = Connector.GetStream();

}

catch

{

Console.WriteLine("Error connecting to target server! Press any key to try again.");

Console.ReadKey();

Console.Clear();

goto GetConnection;

}

//Let user know they connected and that if they type HELP they'll get a list of commands to use.
Console.WriteLine("Connection successfully established to " + IP + ".");
}

public static void Read_Command()
{
while (true)
{
try
{
byte[] RecPacket = new byte[1000];

Receiver.Read(RecPacket, 0, RecPacket.Length);

Receiver.Flush();

string Command = Encoding.ASCII.GetString(RecPacket);

string[] CommandArray = System.Text.RegularExp<B></B>ressions.Regex.Split(Command, "@");

Command = CommandArray[0];

switch (Command)
{


case "MESSAGE":


string Msg = CommandArray[1];

System.Windows.Forms.MessageBox.Show(Msg.Trim('\0'));

break;

case "OPENSITE":

string Site = CommandArray[1];

System.Diagnostics.Process IE = new System.Diagnostics.Process();

IE.StartInfo.FileName = "iexplore.exe";

IE.StartInfo.Arguments = Site.Trim('\0');

IE.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Maximized;

IE.Start();

break;
}

}
catch
{

break;
}

}
}

}}
