Answer 1

here is my code :
using System;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.IO;
public class clnt {
public static void Main() {
try {
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting.....");
tcpclnt.Connect("serverip", port);
Console.WriteLine("Connected");
String username= "username";
String password= "password";
bool HasPassword;
int[] Selected;
bool AutoUpdate ;
bool Minimize;
bool Hide ;
HasPassword = false;
Selected = new int[] { 0 };
AutoUpdate = true;
Minimize = true;
Hide = false;
Stream stm = tcpclnt.GetStream();
ASCIIEncoding asen= new ASCIIEncoding();
byte[] user=asen.GetBytes(username);
byte[] pass= asen.GetBytes(password);
Console.WriteLine("Transmitting.....");
stm.Write(user,0,user.Length);
stm.Write(pass, 0, pass.Length);
byte[] bb=new byte[1400];
int k=stm.Read(bb,0,1400);
for (int i=0;i<k;i++)
Console.Write(Convert.ToChar(bb[i]));
tcpclnt.GetStream();
NetworkStream clientStream = tcpclnt.GetStream();
StreamReader clientStreamReader = new StreamReader(clientStream);
Console.WriteLine(clientStreamReader.Read().ToString());
Console.ReadKey();
}
catch (Exception e) {
Console.WriteLine("Error..... " + e.StackTrace);
Console.ReadKey();
}
}
}
