如何用.net实现两台机子之间的数据间的传送?

可以用TcpClient，TcpListener
抄一段书里的代码：下面实现一个Server
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
class TcpListenerSample
{
  public static void Main()
  {
   int recv;
   byte[] data = new byte[1024];
   TcpListener newsock = new TcpListener(9050); //绑定端口
   newsock.Start();
   Console.WriteLine("Waiting for a client...");
   TcpClient client = newsock.AcceptTcpClient(); //接收一个客户端连接
   NetworkStream ns = client.GetStream(); //获得输入输出流
   string welcome = "Welcome to my test server";
   data = Encoding.ASCII.GetBytes(welcome);
   ns.Write(data, 0, data.Length);
   while(true) //循环接收数据
   {
     data = new byte[1024];
     recv = ns.Read(data, 0, data.Length);
     if (recv == 0)
      break;
  
     Console.WriteLine(
         Encoding.ASCII.GetString(data, 0, recv));
     ns.Write(data, 0, recv);//将接收到的返回给Client
   }
   ns.Close();
   client.Close();
   newsock.Stop();
  }
}

//下面实现一个Client
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
class TcpClientSample
{
  public static void Main()
  {
   byte[] data = new byte[1024];
   string input, stringData;
   TcpClient server;
   try
   {
     server = new TcpClient("127.0.0.1", 9050);//服务器的IP端口
   } catch (SocketException)
   {
     Console.WriteLine("Unable to connect to server");
     return;
   }
   NetworkStream ns = server.GetStream();
   int recv = ns.Read(data, 0, data.Length);
   stringData = Encoding.ASCII.GetString(data, 0, recv);
   Console.WriteLine(stringData);
   while(true)
   {
     input = Console.ReadLine();
     if (input == "exit")//如果输入exit则退出连接
      break;
     ns.Write(Encoding.ASCII.GetBytes(input), 0, input.Length);
     ns.Flush();
     data = new byte[1024];
     recv = ns.Read(data, 0, data.Length);
     stringData = Encoding.ASCII.GetString(data, 0, recv);
     Console.WriteLine(stringData);
   }
   Console.WriteLine("Disconnecting from server...");
   ns.Close();
   server.Close();
  }
}
