[RESOLVED] [VS2010] simplest tcp/ip client and server

What i need it to send a stream of data, the data will consist of 3 numbers, i have tryied finding a sample but they dont work on vs2010, have no idea why, will continue searching.

I am new to c# but i like it a lot coz it's very readable, and similar to VB which i am a bit more familiar with.

The stream can be send as a string also and i can probably make a reader figure out the numbers in the string.

Anyhow any help is appreciated, just take in mind i am a beginner, Thank you.

1) What examples have you tried? What "doesnt" work?
2) the MSDN documentation provides loads of examples.... they work 100% all the time.

hint: take a look at TCPClient, TCPListener and NetworkStream classes.

Hi,

There are tons of examples in the net...I think there are samples too at the
codebank section of this site..

here is the Client part:

C# Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
 
namespace tcp_Klijent
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            TcpClient tcpClient = new TcpClient();
            tcpClient.Connect("127.0.0.1" , 3142);
            if (tcpClient.Connected)
            {
                    NetworkStream NS =tcpClient.GetStream();
            while (NS.CanWrite)
            {
                    Console.WriteLine ("unesi tekst");
                     a:
 
                     Byte[] data = Encoding.ASCII.GetBytes(Console.ReadLine());
 
                       NS.Write(data, 0, data.Length);
                      goto a;
 
 
 
            }
 
 
            }
        }
    }
}

and here is the server part:

C# Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
using System.IO;
using System.Net;
 
 
 
namespace tcp_server
{
    class Program
    {
        static void Main(string[] args)
        {
            Int32 port = 3142;
            IPAddress localAddr = IPAddress.Parse("127.0.0.1");
 
            TcpListener tcpListener = new TcpListener(localAddr , port);
 
            tcpListener.Start();
            for (; ; )
                {
                    TcpClient tcpClient = tcpListener.AcceptTcpClient();
                    if (tcpClient.Connected)
                    {
 
                        NetworkStream NS = tcpClient.GetStream();
                    a:
                        StringBuilder SB = new StringBuilder();
                        Byte[] a = new Byte[1024];
                        int b = 0;
 
                        do
                        {
 
                            b = NS.Read(a, 0, a.Length);
                            SB.AppendFormat("{0}" , Encoding.ASCII.GetString(a,0,b));
 
 
                        
                        }
 
                        while (NS.DataAvailable);
                        
                        Console.WriteLine("poruka klijenta:  " + SB);
                        goto a;
                    
                    }
 
 
            
            
                }
 
 
        }
    }
}

Thank you for the hints, hopefully this will be helpful to someone :)

never use goto....

the examples on MSDN are the ones to really follow
