界面设计

2.图片PictureBox设置
(1)Imge背景设置?

?2）SizeMode选择StrechImage，会把PictureBox图片框铺满，自适应图片框的大小。

二、连接服务器

1.在Form中初始化进入游戏：

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！");
    }
}

?

三、客户端向服务器发送数据

1.双击button12

?

 private void button12_Click(object sender, EventArgs e)
        {
            //判断连接是否断开
            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");
            }
        }

四、播放背景音乐

1.设置音乐按钮如下，一个Lable和两个Button

2.添加WindowsMediaPlayer控件，工具箱->常规右键->选择项?

?

3.勾选COM组件中的Windows Media Player?双击Button13（播放键）设置代码.如下

        private void button13_Click(object sender, EventArgs e)
        {
            string s = @"C:\Users\86199\Music\xz\Something just like this.mp3";
            axWindowsMediaPlayer1.URL = s;
        }
        private void button14_Click(object sender, EventArgs e)
        {
            //用于暂停正在播放的背景音乐
            axWindowsMediaPlayer1.Ctlcontrols.pause();
        }

?

切换游戏背景图片

1.添加Timer组件

Timer的属性Enable设置True?

添加代码如下

int flag = 0;
        private void timer1_Tick(object sender, EventArgs e)
        {
            flag++;
            string picturePath = @"F:\game\pictures\" + flag + ".jpg";
            pictureBox1.Image = Image.FromFile(picturePath);
            if (flag ==3)
            {
                flag = 0;
            }
        }
