Probably simple problem with networking

Hi, I'm trying to make an application communicating over TCP/IP. It should do only one thing - write received data to console and terminate itself when "exit" received. Problem is that if I send some string to this application, it'll receive that string and many unwanted "new line" characters on its end.
 
Examle:
 
If I send
 
"some_string"
 
application display
 
"some_string
 
 
 
 
 
 
"
 
I can't find the reason why it does so. Here's my code:

using System;
using System.IO;
using System.Text;
using System.Net;
using System.Net.Sockets;

namespace NetPokus
{
    class NetPokus
    {

        [STAThread]
        static void Main(string[] args)
        {
            string recv;
            Odpovedi odp;

            try
            {
               odp = new Odpovedi();
            }
            catch (SocketException ex)
            {
               Console.WriteLine(ex.ToString());
                Console.ReadLine();
               return;
            }

            while (true)
            {
               odp.Write("Waiting for command\n");
               recv = odp.Read();

               if (recv == "exit")
               {
                    break;
                }
               else
                {
                    Console.Write(recv);
                }
            }

           odp.Close();
       }
    }

    public class Odpovedi
    {
        TcpClient client;
        NetworkStream nstr;
        byte[] received;
        byte[] toSend;

        public Odpovedi()
        {
           client = new TcpClient("127.0.0.1", 1234);
            nstr = client.GetStream();
        }

        public void Write(string msg)
        {
            toSend = Encoding.ASCII.GetBytes(msg);
            nstr.Write(toSend, 0, toSend.Length);
        }

        public string Read()
        {
            received = new byte[client.ReceiveBufferSize];
            nstr.Read(received, 0, client.ReceiveBufferSize);
            return Encoding.ASCII.GetString(received);
        }

        public void Close()
        {
            client.Close();
        }
   }
}
