TCP实验关于C#CS编程.docxVIP

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 实验目的利用C#编程，通过TCP的数据连接与传输的方式，编写一个基于TCP的C\S模式的简易聊天程序。实验思想与方案 TCP\IP协议栈。TCP\IP参考模型分为四个层次：应用层，传输层，网络互连层与主机到网络层。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;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Net;using System.Net.Sockets;using System.Threading;namespace TCPClient{publicpartialclassForm1 : Form {publicSocket newclient;publicbool Connected;publicThread myThread;publicdelegatevoidMyInvoke(string str);public Form1() { InitializeComponent(); }publicvoid Connect() {byte[] data = newbyte[1024]; newclient = newSocket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);string ipadd = serverIP.Text.Trim();int port = Convert.ToInt32(serverPort.Text.Trim());IPEndPoint ie = newIPEndPoint(IPAddress.Parse(ipadd), port);try { newclient.Connect(ie); connect.Enabled = false; Connected = true; }catch (SocketException e) {MessageBox.Show(连￠?接¨?服¤t务?器??失o?ì败?¨1 + e.Message);return; }ThreadStart myThreaddelegate = newThreadStart(ReceiveMsg); myThread = newThread(myThreaddelegate); myThread.Start(); }publicvoid ReceiveMsg() {while (true) {byte[] data = newbyte[1024];int recv = newclient.Receive(data);string stringdata = Encoding.UTF8.GetString(data, 0, recv); showMsg(stringdata + \r\n);//receiveMsg.AppendText(stringdata + \r\n); } }publicvoid showMsg(string msg) { {//在¨2线?程¨?里¤?以°?安?2全¨?方¤?式o?调ì??用??控?件tif (receiveMsg.InvokeRequired) {MyInvoke _myinvoke = newMyInvoke(showMsg); receiveMsg.Invoke(_myinvoke, newobject[] { msg }); }else { receiveMsg.
