课程实验报告课程名称：C#网络编程实验项目名称：实验三窗体TCP通信专业班级：B11522姓名：学号：201320120指导教师：完成时间：2014 年 3 月24 日计算机科学与工程系实验三窗体TCP通信一、实验目的1、掌握SOKCET面向连接通信的基本原理；2、掌握窗体程序下套接字通信程序中服务器端的通信流程；3、掌握窗体程序下套接字通信程序中客户端的通信流程；二、实验内容1. 完善控制台程序，实现一对多服务器端和客户端的程序代码，其中服务器只需接收多个客户端的信息，无需给每一个客户端发送回复。

2. 实现窗体程序下tcp通信中，服务器端和客户端的通信程序，实现一对一多次通信。

3. 尝试服务器能和多个客户端通信，并行模式（服务器可以同时和多个客户端进行收发信息的通信），提示：服务器端程序每来一客户端连接请求，需要打开一个新的窗口来实现和客户端的通信。

（此部分内容，实验报告上可以不体现）三、实验过程第一题：服务器端代码：namespace server_more{class Program{private static byte[] result = new byte[1024];private static int myprot = 8889;static Socket serverSocket;static void Main(string[] args){IPAddress ip = IPAddress.Parse("127.0.0.1");serverSocket=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);serverSocket.Bind(new IPEndPoint(ip, myprot));serverSocket.Listen(10);Console.WriteLine("启动监听成功|", serverSocket.LocalEndPoint.ToString());Thread myThred = new Thread(ListenClientConnect);Console.ReadLine();}private static void ListenClientConnect(){ while (true){ Socket clientsocket = serverSocket.Accept();clientsocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));Thread receiveThred = new Thread(ReceiveMessage);receiveThred.Start(clientsocket); } }private static void ReceiveMessage(object clientSocket){Socket myClientSocket = (Socket)clientSocket;while (true){try{int receiveNumber = myClientSocket.Receive(result);Console.WriteLine("接受客户端消息{1}", myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber)); }catch (Exception ex){Console.WriteLine(ex.Message);myClientSocket.Shutdown(SocketShutdown.Both);myClientSocket.Close();break; }｝｝｝客户端代码：namespace server_client{class Program{private static byte[] result=new byte[1024];static void Main(string[] args){IPAddress ip = IPAddress.Parse("127.0.0.1");Socket clinetsocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);try{clinetsocket.Connect(new IPEndPoint(ip, 8889));Console.WriteLine("连接服务器成功！");}catch{ Console.WriteLine("连接服务器失败！");return; }int receiveLength=clinetsocket.Receive(result);Console.WriteLine("接收服务器消息{0}",Encoding.ASCII.GetString(result,0,receiveLength));for(int i=0;i<10;i++){try{ Console.WriteLine("请输入要给服务器发送的信息：");senstr = Console.ReadLine();if (senstr != "0"){clinetsocket.Send(Encoding.ASCII.GetBytes(senstr));Console.WriteLine("向服务器发送消息：{0}", senstr);｝｝catch{ clinetsocket.Shutdown(SocketShutdown.Both);clinetsocket.Close();break;｝｝Console.WriteLine("发送完毕，按任意键继续：");Console.ReadLine();｝｝｝第二题服务器代码：namespace server_one{public partial class Form1 : Form{public Form1(){InitializeComponent(); }Socket communisoc;Socket listensoc;delegate void richtbdel(string recvstr);void addstr(string add){ if (richTextBox1.InvokeRequired){ richtbdel del = addstr;richTextBox1.Invoke(del, add); }elserichTextBox1.AppendText(add); }void recvfun(){ while (true)try{ byte[] recv = new byte[100];int len = communisoc.Receive(recv);addstr(Encoding.Default.GetString(recv, 0, len)); }catch{break;} }private void button2_Click(object sender, EventArgs e){listensoc=new Socket(AddressFamily.InterNetwork,SocketType.Stream, rotocolType.Tcp);IPAddress serIp = IPAddress.Parse("127.0.0.1");IPEndPoint IpP = new IPEndPoint(serIp, 6666);listensoc.Bind(IpP);listensoc.Listen(3);communisoc = listensoc.Accept();communisoc.Send(Encoding.Default.GetBytes("hello i am server!"));Thread t = new Thread(recvfun);t.IsBackground = true;t.Start(); }private void button1_Click(object sender, EventArgs e){communisoc.Send(Encoding.Default.GetBytes(textBox1.Text));}private void Form1_FormClosing(object sender, FormClosingEventArgs e){communisoc.Shutdown(SocketShutdown.Both);communisoc.Close();listensoc.Close(); ｝｝｝客户端代码：namespace client_one{public partial class Form1 : Form{ Socket clisoc;delegate void richtbdel(string recvstr);void addstr(string add){ if (richTextBox1.InvokeRequired){ richtbdel del = addstr;richTextBox1.Invoke(del, add);

}void accthread(){while (true){ communisoc = listensoc.Accept();communisoc.Send(Encoding.Default.GetBytes("hello i am server!"));Thread t = new Thread(openf2);t.IsBackground = true;t.Start(communisoc);}}void openf2(object comsoc){Form2 f2 = new Form2(communisoc);f2.ShowDialog();}private void button1_Click(object sender, EventArgs e){listensoc=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);IPAddress serIp = IPAddress.Parse("127.0.0.1");IPEndPoint ipP = new IPEndPoint(serIp, 6666);listensoc.Bind(ipP);listensoc.Listen(3);Thread t = new Thread(accthread);t.IsBackground = true;t.Start();}private void Form1_FormClosing(object sender, FormClosingEventArgs e){ listensoc.Close();
