TCP实验关于C#的CS编程

1、组C/S模式的编程实例C#语言编写报告人: 实验分组： 班级： 学号： 负责内容：TCPserver 1. 实验目的 利用C#编程，通过TCP的数据连接和传输的方式，编写一个基于TCP的CS模式的简易聊天程序。2. 实验思想和方案 TCPIP协议栈。TCPIP参考模型分为四个层次：应用层，传输层，网络互连层和主机到网络层。在TCP中常用的类有：TcpListener类，TcpClient类，NetworkStream等。通讯流程图：部分源代码：using System;using System.Collections.Generic;using System.ComponentModel;us
