C#WinForm,TCP调试工具

Server端配置 参考代码

1）设置基本参数

/// <summary>
///以本机作测试 
/// </summary>
private IPAddress serverIP = IPAddress.Parse("192.168.0.105");
/// <summary>
///完整终端地址 
/// </summary>
private IPEndPoint serverFullAddr;
/// <summary>
/// 连接套接字
/// </summary>
private Socket sock;

2）启动服务器端

serverIP = IPAddress.Parse(tbxIP.Text);
            try
            {
                //设置IP和端口
                serverFullAddr = new IPEndPoint(serverIP, int.Parse(tbxPort.Text));
                sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                //指定本地主机地址和端口号
                sock.Connect(serverFullAddr);
                btnConn.Enabled = false;
                MessageBox.Show("连接成功");
                btnClose.Enabled = true;
                sock.Close();

            }
            catch (Exception ee)
            {

 　　　　　　　　　　MessageBox.Show("连接失败"+ee.ToString());

 　　　　　　}

3）停止服务端

sock.Close();//关闭Socket连接

Client端 参考代码

1）设置基本参数

/// <summary>
        /// 以本机作测试,IP
        /// </summary>
        private IPAddress serverIP = IPAddress.Parse("127.0.0.1");


        /// <summary>
        /// 完整终端地址
        /// </summary>
        private IPEndPoint serverFullAddr;
        /// <summary>
        /// 连接套接字
        /// </summary>
        private Socket sock;
        /// <summary>
        /// 监听线程
        /// </summary>
        Thread myThead = null;

2）启动服务器  

myThead = new Thread(new ThreadStart(BeginListen));
            myThead.Start();
            btnStart.Enabled = false;
            btnstop.Enabled = true;

3）设置侦听

/// <summary>
        /// 设置监听
        /// </summary>
        private void BeginListen()
        {
            //IP
            serverIP = IPAddress.Parse(tbxIP.Text);
            //设置IP，端口
            serverFullAddr = new IPEndPoint(serverIP, int.Parse(tbxPort.Text));
            sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            //指定本地主机地址和端口号
            sock.Bind(serverFullAddr);
            lbxMessage.Invoke(new SetTextCallback(SetText), "启动成功 时间:" + DateTime.Now, 1);
            byte[] message = new byte[1024];
            string mess = "";
            while (true)
            {
                try
                {
                    sock.Listen(5);//设置监听频率
                    Socket newSocket = sock.Accept();//阻塞方式
                    int bytes = newSocket.Receive(message);//接收数据
                    mess = Encoding.Default.GetString(message, 0, bytes);//对接收字节编码（S与C 两端编码格式必须一致不然中文乱码）（当接收的字节大于1024的时候 这应该是循环接收，测试就没有那样写了）
                    //do
                    //{
                    //    bytes = newSocket.Receive(message, message.Length, 0);
                    //    mess = mess + Encoding.ASCII.GetString(message, 0, bytes);
                    //}
                    //while (bytes > 0);

                    lbxMessage.Invoke(new SetTextCallback(SetText), mess, 1);//子线程操作主线程UI控件


                    //获取客户端的IP和端口
                    string ip11 = newSocket.RemoteEndPoint.AddressFamily.ToString();

                    mess = "已接收数据： "+ mess +" 来自：" +ip11+ " 当前时间为：" + DateTime.Now; //处理数据
                    newSocket.Send(Encoding.Default.GetBytes(mess));//向客户端发送数据

                }
                catch (SocketException se)
                {
                    lbxMessage.Invoke(new SetTextCallback(SetText), mess + se, 1);

                }
            }
        }

4）生命委托

delegate void SetTextCallback(string text, int num);
        private void SetText(string text, int num)
        {
            lbxMessage.Items.Add(text);
        }

5）停止服务

try
            {
                sock.Close();
                //中止监听
                myThead.Abort();
                btnStart.Enabled = true;
                btnstop.Enabled = false;
                lbxMessage.Items.Add("停止成功 时间:" + DateTime.Now);
            }
            catch (Exception ee)
            {
                lbxMessage.Text = "停止失败。。" + ee;
            }

5）接收消息

private void Sending(IAsyncResult rec_socket)
        {
            //发送给客户端的消息
            string sendmsg = "";
            Socket socket = (Socket)rec_socket.AsyncState;
            try
            {
                if (socket.Connected)
                {
                    byte[] msgBuff = Encoding.UTF8.GetBytes(sendmsg);
                    socket.Send(msgBuff);
                }
                else
                {
                    Console.WriteLine("Error!", "Error!");
                }
            }
            catch
            {
                Console.WriteLine("Error!", "Error!");
            }
        }
