1、音乐播放器开发模块doc音乐播放器开发文档1.动能介绍开始菜单包含：a.添加音乐文件b.添加音乐文件夹c.添加背景图片d.退出播放模式：a.单曲循环 b.顺序循环 c.列表播放 d.随机播放透明度：透明百分之几或不透明界面设置：迷你模式关于：版本信息2、代码讲解全局变量：private SoundPlayer Player = new SoundPlayer(); private SoundPlayer SencondPlayer = new SoundPlayer(); Image image = new Image500;/存放图片数组 private int Imagecount = 0

2、;/计算背景图片数 private int order = 0;/存储图片总数 private int fileCount = 0;/数组中计算音乐文件数 private int fileCount1 = 0;/文件系数 string musicfile = new string500;/存放音乐文件 int selectOne = 0;/双击事件选择的音乐的序号 static int stop = 2;/判断是暂停还是播放 static double CurrentPosition = 0;/获得文件播放的位置 static int State = 0;/当前状态等于时进行单曲循环，等于零的

3、时候进行顺序播放, /当前状态等于时为随机播放/当前状态等于时为列表播放OpenFileDialog openfile = new OpenFileDialog();/打开本地磁盘对话框添加音乐文件private void 添加文件ToolStripMenuItem1_Click(object sender, EventArgs e) fileCount1+; openfile.Filter = |*.mp3; openfile.Multiselect = true;/支持多行文件 try if (DialogResult.OK = openfile.ShowDialog() musicfil

4、efileCount = openfile.FileName; FileInfo fileinfo = new FileInfo(musicfilefileCount); /FileInfo类是将文件去相对路径 string filename = fileCount1.ToString() + _ + fileinfo.Name;/使音乐名前加序号并只取文件名 this.listBox1.Items.Add(filename);/将文件多行显示在列表中 this.musicname.Text = fileinfo.Name; PlayAndStop(fileCount); /启动MP3播放器

5、fileCount+; catch (Exception) MessageBox.Show(musicfilefileCount.ToString(); 添加音乐文件夹private void 添加文件夹ToolStripMenuItem1_Click(object sender, EventArgs e) FolderBrowserDialog folder = new FolderBrowserDialog();/文件夹初始化 folder.ShowDialog(); string file = Directory.GetFiles(folder.SelectedPath.ToString

6、(), *.MP3);/使用数组存得到的文件 int fileName = 0; try foreach (string Music in file) fileCount1+; FileInfo f = new FileInfo(filefileName);/读取文件 musicfilefileCount = filefileName; fileName+; fileCount+;/数组存文件数 string total = fileCount1.ToString() + _ + f.Name;/f.Name只取f中的文件名 this.listBox1.Items.Add(total); ca

7、tch (Exception) MessageBox.Show(输入的音乐总数超出！); 添加背景图片private void 添加背景图片ToolStripMenuItem1_Click(object sender, EventArgs e) FolderBrowserDialog folder = new FolderBrowserDialog(); folder.ShowDialog(); string BGfile = Directory.GetFiles(folder.SelectedPath.ToString(), *.jpg); foreach (string pic in BG

8、file) imageorder = Image.FromFile(pic); order+; this.timer1.Enabled = true;/启动定时器 定时器private void timer1_Tick(object sender, EventArgs e) this.BGpicture.Image = imageImagecount; if (Imagecount = order-1) Imagecount = 0; else Imagecount+; 退出播放器private void 退出ToolStripMenuItem1_Click(object sender, Ev

12、Item1_Click(object sender, EventArgs e) State = 2; 调用播放模式的事件 /改变播放状态，当音乐一首播放完后转入下一首，有线程调用 private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e) Thread thread = new Thread(new ThreadStart(PlayThread); /顺序播放 if (axWindowsMediaPlayer1.playState

14、um = Num.Next(0, fileCount); FileInfo f = new FileInfo(musicfileSum); this.musicname.Text = f.Name; selectOne = Sum; thread.Start(); catch (Exception) return; /列表播放 try if (axWindowsMediaPlayer1.playState = WMPLib.WMPPlayState.wmppsMediaEnded & State = 3) if (selectOne fileCount - 2) selectOne = 0;

15、else selectOne+; thread.Start(); catch (Exception) return; 调用线程private void PlayThread() PlayAndStop(selectOne)；调用音乐播放功能 制作界面透明功能/透明度% private void toolStripMenuItem7_Click(object sender, EventArgs e) this.Opacity = 0.1; /透明度% private void toolStripMenuItem8_Click(object sender, EventArgs e) this.Op
