1、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
2、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_moreclass Programprivate static byte result = new byte1024;private static int myprot = 8889;static Socket serverSocket;static void M
3、ain(string args)IPAddress ip = IPAddress.Parse(127.0.0.1);serverSocket=newSocket(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 T
4、hread(ListenClientConnect); myThred.Start();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(clientsock
5、et); private static void ReceiveMessage(object clientSocket)Socket myClientSocket = (Socket)clientSocket;while (true)tryint receiveNumber = myClientSocket.Receive(result);Console.WriteLine(接受客户端消息1, myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber);catch (E
6、xception ex)Console.WriteLine(ex.Message);myClientSocket.Shutdown(SocketShutdown.Both);myClientSocket.Close();break; 客户端代码：namespace server_clientclass Programprivate static byte result=new byte1024;static void Main(string args) IPAddress ip = IPAddress.Parse(127.0.0.1); Socket clinetsocket = new So
7、cket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);tryclinetsocket.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,rece
8、iveLength);string senstr;for(int i=0;i10;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.
9、WriteLine(发送完毕，按任意键继续：);Console.ReadLine(); 第二题服务器代码：namespace server_onepublic partial class Form1 : Formpublic Form1()InitializeComponent(); Socket communisoc;Socket listensoc;delegate void richtbdel(string recvstr);void addstr(string add) if (richTextBox1.InvokeRequired) richtbdel del = addstr; r
10、ichTextBox1.Invoke(del, add); elserichTextBox1.AppendText(add); void recvfun() while (true)try byte recv = new byte100;int len = communisoc.Receive(recv);addstr(Encoding.Default.GetString(recv, 0, len); catch break; private void button2_Click(object sender, EventArgs e)listensoc=newSocket(AddressFam
11、ily.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(r
12、ecvfun);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();
13、客户端代码：namespace client_onepublic 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); elserichTextBox1.AppendText(add); void recvfun() while (true)trybyte recv =
14、 new byte100;int len = clisoc.Receive(recv);addstr(Encoding.Default.GetString(recv, 0, len);catch break; public Form1() private void button2_Click(object sender, EventArgs e) clisoc = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);IPAddress serIp = IPAddress.Parse(127.0.
15、0.1);IPEndPoint IpP = new IPEndPoint(serIp, 6666);clisoc.Connect(IpP);clisoc.Send(Encoding.Default.GetBytes(i am client!);Thread t = new Thread(recvfun);t.IsBackground = true;t.Start();private void button1_Click(object sender, EventArgs e)clisoc.Send(Encoding.Default.GetBytes(textBox1.Text);private void Form1_FormClosing(object sender, FormClosingEventArgs e)clisoc.Shutdown(SocketShutdown.Both);clisoc.Close();
