tcpclient与tcplistener

客户端

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

namespace tcpclient
{
    class Program
    {
        static void Main(string[] args)
        {
            //当我们创建tcpclient对象的时候，就会跟server建立连接
            TcpClient client = new TcpClient("192.168.3.41",7788);

            NetworkStream stream = client.GetStream();//通过网络流进行数据交换

            while (true)
            {
                string message = Console.ReadLine();
                byte[] data = Encoding.UTF8.GetBytes(message);
                stream.Write(data, 0, data.Length);
            }
                  
            stream.Close();
            client.Close();
            Console.ReadKey();

        }
    }
}

服务器端

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

namespace tcplistener
{
    class Program
    {
        static void Main(string[] args)
        {
            //TcpListener对Socket进行了一层封装，这个类里面自己会去创建socket对象
            TcpListener listener = new TcpListener(IPAddress.Parse("192.168.3.41"), 7788);

            //开始进行监听
            listener.Start();

            //等待客户端链接过来
            TcpClient client = listener.AcceptTcpClient();

            //取得客户端发送过来的数据
            NetworkStream stream= client.GetStream(); //得到了网络流，从这个网络流可以取得客户端发送过来的数据

            byte[] data = new byte[1024];


            while (true)
            {
                int length = stream.Read(data, 0, 1024);//读取数据 1024表示最大读取字节数
                string message = Encoding.UTF8.GetString(data, 0, length);
                Console.WriteLine("收到了消息:" + message);

            }
            
            stream.Close();
            client.Close();
            listener.Stop();

            Console.ReadKey();

        }
    }
}
