[网络协议]游戏客户端编程

一、项目创建以及页面设置

（一）新建项目

二、窗体设计

打开窗口设计页面，双击窗体可以跳转至代码编辑页面，将Form1()替换成以下代码：

private NetworkStream stream;
private TcpClient tcpClient = new TcpClient();
public Form1()
{
      InitializeComponent();
      try
            {
                //向指定的IP地址的服务器发出连接请求
                tcpClient.Connect("10.1.230.74", 3900);
                listBox1.Items.Add("连接成功！");
                stream = tcpClient.GetStream();
                byte[] data = new byte[1024];
                //判断网络流是否可读            
                if (stream.CanRead)
                {
                    int len = stream.Read(data, 0, data.Length);
                    //Encoding ToEncoding = Encoding.GetEncoding("UTF-8");
                    //Encoding FromEncoding = Encoding.GetEncoding("GB2312");
                    //data=Encoding.Convert(FromEncoding, ToEncoding, data);
                    //string msg = Encoding.UTF8.GetString(data, 0, data.Length);
                    string msg = Encoding.Default.GetString(data, 0, data.Length);
                    string str = "\r\n";
                    char[] str1 = str.ToCharArray();
                    string[] msg1=msg.Split(str1);
                    for(int j = 0; j < msg1.Length; j++)
                    {
                        listBox1.Items.Add(msg1[j]);
                    }
                }
            }
            catch
            {
                listBox1.Items.Add("服务器未启动！");
            }
}

在头文件中添加using System.Net.Sockets;

代码实现

（1）实现连接到服务器并接受数据

双击进入游戏的Button
代码：

private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                //向指定的IP地址的服务器发出连接请求
                tcpClient.Connect("10.1.230.41", 3900);
                listBox1.Items.Add("连接成功！");
                stream = tcpClient.GetStream();
                byte[] data = new byte[1024];
                //判断网络流是否可读            
                if (stream.CanRead)
                {
                    int len = stream.Read(data, 0, data.Length);
                    string msg = Encoding.Default.GetString(data, 0, data.Length);
                    string str = "\r\n";
                    char[] str1 = str.ToCharArray();
                    string[] msg1 = msg.Split(str1);
                    for (int j = 0; j < msg1.Length; j++)
                    {
                        listBox1.Items.Add(msg1[j]);
                         music_play();
                    }
                }
            }
            catch
            {
                listBox1.Items.Add("连接失败！");
            }
        }

（2）实现客户端发送数据到服务器
双击发送的button
代码：

private void button12_Click(object sender, EventArgs e)
        {
            music_play();
            if (tcpClient.Connected)
            {
                //向服务器发送数据
                string msg = textBox1.Text;
                Byte[] outbytes = System.Text.Encoding.Default.GetBytes(msg + "\n");
                stream.Write(outbytes, 0, outbytes.Length);
                byte[] data = new byte[1024];
                //接收服务器回复数据
                if (stream.CanRead)
                {
                    int len = stream.Read(data, 0, data.Length);
                    string msg1 = Encoding.Default.GetString(data, 0, data.Length);
                    string str = "\r\n";
                    char[] str1 = str.ToCharArray();
                    string[] msg2 = msg1.Split(str1);
                    for (int j = 0; j < msg2.Length; j++)
                    {
                        listBox1.Items.Add(msg2[j]);
                    }
                }
            }
            else
            {
                listBox1.Items.Add("连接已断开");
            }
            textBox1.Clear();
        }

播放背景音乐,在项目引用里增加COM组件WindowsMediaPlayer

 private void music_play()
        {
			WMPLib.WindowsMediaPlayer Player = new WMPLib.WindowsMediaPlayer();
            Player.URL = @"D:\CloudMusic\阿保剛 - Karma -Piano version-.mp3";
            Player.controls.play();
        }

图片代码

 //图片
            System.Timers.Timer timer = new System.Timers.Timer();
            timer.Interval = 30000;
            int i = 0;
            timer.Elapsed += delegate
            {
                i++;
                Image image = Image.FromFile(i + ".jpg");
                //图片的文件名从1.jpg开始
                pictureBox1.Image = image;
                if (i == 3) i = 0;
                //当文件名为3.jpg时即将i重置为0
            };
            timer.Start();

运行界面
