[RESOLVED] Error receiving text by socket

[lelejau]

I have this code for server:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
using System.Net.Sockets;
using System.Threading;

namespace ConsoleApplication2
{
     class User  
     {  
         public TcpClient conn = null;  
         public string name = "Anônimo";  
         public string ip;  
   
         public NetworkStream ns;  
         public StreamWriter w;  
         public StreamReader r;  
   
         public int tent = 0;  
         public int win = 0;  
   
         public User(TcpClient conn)  
         {  
             this.conn = conn;  
   
             this.ns = this.conn.GetStream();  
   
             this.r = new StreamReader(this.ns);  
             this.w = new StreamWriter(this.ns);  
         }  
   
         public string Name  
         {  
             get  
             {  
                 return this.name;  
             }  
             set  
             {  
                 this.name = value;  
             }  
         }  
     } 
    
    class Program
    {
        private static Socket Soquete;
        private static TcpListener tcpl = new TcpListener(IPAddress.Parse(IPAddress.Loopback.ToString()), 10009);
        static TcpClient a;

        public static bool Iniciar()
        {
            Int32 porta = 10009;
            User user;
            
            try
            {
                Soquete = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                Soquete.Bind(new IPEndPoint(IPAddress.Any, porta));
                Soquete.Listen(1);
                Console.WriteLine("Server online at por " + porta + ", IP:" + IPAddress.Loopback.ToString() + ".");
                try
                {
                    Int32 usuarios = 0;
                    tcpl.Start();
                    Console.WriteLine("Waiting for connections on port "+ porta +".");
                    while (true)
                    {

                        a = tcpl.AcceptTcpClient();

                     user = new User(a);  
                        usuarios++;
                        user.ip = ((IPEndPoint)a.Client.RemoteEndPoint).Address.ToString();  

                        //Console.WriteLine(String.Format("Client {0} connected -> IP: {1}",usuarios, user.ip));
                        try
                        {

                            user.r.ReadLine();
                        }
                        catch(Exception e)
                        {
                            Console.WriteLine("Error while reading data");
                            Console.WriteLine(e.ToString());
                        }
                  }
                }
              
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
                    return true;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                return false;
            }
        }
        static void Main(string[] args)
        {
            Iniciar();
            Console.ReadKey();
        }
    }
}

This code for client:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
using System.Net.Sockets;
using System.Threading;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            IPAddress host = IPAddress.Parse("127.0.0.1");
            IPEndPoint hostep = new IPEndPoint(host, 10009);
            Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            try
            {
                sock.Connect(hostep);
            }
            catch (SocketException e)
            {
                Console.WriteLine("Problem connecting to host");
                Console.WriteLine(e.ToString());
                sock.Close();
                return;
            }

            try
            {
                sock.Send(Encoding.ASCII.GetBytes("testing"));
            }
            catch (SocketException e)
            {
                Console.WriteLine("Problem sending data");
                Console.WriteLine(e.ToString());
                sock.Close();
                return;
            } 
        }

    }
}

But when i run client to send text, server returns error! The error is in PT-BR, so i wont put it here, because , if I translate it, it will be not so right.

Anyone can help? I dont know what means this error!

This is just a quick guess (I haven't done any real socket programming in a while and I can't write any test code right now) but I think what you want to do is:

 
     try
    {
         byte[] buffer = new byte[256];
         int bytesReceived = user.ns.read(buffer, 0, buffer.length);
         string message;
         message =System.Text.Encoding.ASCII.GetString(buffer , 0, bytesReceived);
          Console.WriteLine("Server received: " + message + " from client");
         //user.r.ReadLine();
     }
     catch(Exception e)
     {
          Console.WriteLine("Error while reading data");
          Console.WriteLine(e.ToString());
     }

I should paste this into server project?
