TCPlistener和TCPClient

利用一个对tcp封装的类来实现服务器端
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

internal class Test
{
    public static void Main()
    {
        TcpListener listener=new TcpListener(IPAddress.Parse("127.0.0.1"),7788);
        //创建tcp监听
        listener.Start();
        //开始监听
        TcpClient client = listener.AcceptTcpClient();
        //当监听到一个客户端时就会返回一个TcpClinet对象
        NetworkStream stream = client.GetStream();
        //从客户中取得流
        byte[]data=new byte[1024];
        int len = stream.Read(data, 0,1024);
        //从流中取得数据
        string str = Encoding.UTF8.GetString(data, 0, len);
        Console.WriteLine(str);
        stream.Close();
        client.Close();
        listener.Stop();
        Console.ReadLine();
    }
}

客户端
using System;
using System.Net.Sockets;
using System.Text;

internal class Test
{
    public static void Main()
    {
        TcpClient client=new TcpClient("127.0.0.1",7788);
        NetworkStream stream = client.GetStream();
        //获取流
        string str = Console.ReadLine();
        Byte[] data = Encoding.UTF8.GetBytes(str);
        stream.Write(data,0,data.Length);
        //将数据写入
        stream.Close();
        client.Close();
        Console.ReadLine();
    }
}
