C#开发音乐播放器.docx

功能简介：1、循环模式：顺不播放axWMusicPlayer.settings.setMode(shuffle, false); 全部循环axWMusicPlayer.settings.setMode(loop, true); 随机播放axWMusicPlayer.settings.setMode(shuffle, true); 2、模拟定时关机程序写到定时关机，具体的调用定时关机程序省略了，程序中相应地方有注解。定时关机代码 1 private void 关机时间toolStripTextBox_KeyPress(object sender, KeyPressEventArgs e)2 3 if (e.KeyChar = (char)Keys.Enter & 关机时间toolStripTextBox.Text != )4 5 try6 7 DateTime time = DateTime.Parse(关机时间toolStripTextBox.Text);8 Timefont font = new Timefont(time.Hour, time.Minute, 0);9 if (font.CompareTo(new Timefont(DateTime.Now.Hour, DateTime.Now.Minute, 0) = 0) /当前关机时间10 11 if (MessageBox.Show(你设定的关机时间是当前计算机时间，是否直接关机？, 提示, MessageBoxButtons.YesNo, MessageBoxIcon.Information) = DialogResult.OK)12 13 MynotifyIcon.Icon = Icon.ExtractAssociatedIcon(PathBase + Images + ShutDown_notifyIcon.ico);14 /15 /调用关机程序16 /17 18 else19 20 return;21 22 23 if (font.CompareTo(new Timefont(DateTime.Now.Hour, DateTime.Now.Minute, 0) 0) /有效关机时间29 30 31 ShutDownTime = 关机时间toolStripTextBox.Text;32 MessageBox.Show(成功设置定时关机，计算机将于“ + ShutDownTime + ”关机 *, 提示, MessageBoxButtons.OK, MessageBoxIcon.Information);33 this.关机时间toolStripTextBox.Visible = false;34 this.取消定时关机QToolStripMenuItem.Visible = true;35 36 /37 /调用关机程序38 /39 40 41 catch42 43 MessageBox.Show(日期格式不正确，请重新输入。, 提示, MessageBoxButtons.OK, MessageBoxIcon.Information);44 return;45 46 47 if (e.KeyChar = (char)Keys.Enter & 关机时间toolStripTextBox.Text = )48 49 关机时间toolStripTextBox.Visible = false;50 51 3、歌曲列表信息保存在XML文件中添加歌曲保存代码 1 private void btnList_Click(object sender, EventArgs e) /添加歌曲2 3 openFileDialog1.Title = 添加歌曲;4 openFileDialog1.FileName = ;5 openFileDialog1.Multiselect = true;6 openFileDialog1.Filter = Mp3文件|*.mp3|Wav文件|*.wav|Wma文件|*.wma|Wmv文件|*.wmv|所有格式|*.*;7 openFileDialog1.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyMusic);8 try9 10 if (openFileDialog1.ShowDialog() = DialogResult.OK)11 12 /IsCreateXmlFile();13 XmlDocument xmldoc = new XmlDocument();14 xmldoc.Load(xmlfile);15 XmlNode root = xmldoc.SelectSingleNode(MusicList);16 string FileNamesList = openFileDialog1.FileNames;17 foreach (string file in FileNamesList)18 19 string filename= Path.GetFileName(file).Substring(0,Path.GetFileName(file).LastIndexOf(.);20 axWMusicPlayer.currentPlaylist.appendItem(axWMusicPlayer.newMedia(file);21 XmlElement newelement = xmldoc.CreateElement(MusicProperty);22 newelement.SetAttribute(MusicUrl, file);23 newelement.SetAttribute(MusicName, filename);24 newelement.SetAttribute(LikeCount, 0);25 root.AppendChild(newelement);26 Application.DoEvents();27 28 xmldoc.Save(xmlfile);29 30 31 catch(Exception ex)32 33 MessageBox.Show(ex.Message, 提示, MessageBoxButtons.OK, MessageBoxIcon.Information);34 35 4、主界面上的喜爱按钮实现的是歌曲排列顺序在下次启动程序后，程序会自动将喜爱点击次数多的歌曲排到前面喜爱按钮事件 1 private void btnFavorite_Click(object sender, EventArgs e) /喜爱2 3 if (axWMusicPlayer.currentMedia != null)4 5 XmlDocument doc = new XmlDocument();6 doc.Load(xmlfile);7 XmlNodeList nodelist = doc.SelectSingleNode(MusicList).ChildNodes;8 foreach (XmlNode node in nodelist)9 10 XmlElement element = (XmlElement)node; /将XmlNode节点node转化成XmlElement型的node11 if (element.GetAttribute(MusicUrl) = axWMusicPlayer.currentMedia.sourceURL)12 13 int likecount = Convert.ToInt32(element.GetAttribute(LikeCount) + 1;14 element.SetAttribute(LikeCount, likecount.ToString();15 16 17 doc.Save(xmlfile);18 19 5、点击进度条歌曲直接跳到当前位置继续播放设置当前播放位置private void pictureBox2_MouseDown(object sender, MouseEventArgs e) if (e.Button = MouseButtons.Left) axWMusicPlayer.Ctlcontrols.currentPosition = e.X * axWMusicPlayer.currentMedia.duration / 170; 注解：170为进度条总长度6、进度条采用自定义控件自定义进度条控件代码 1 / 2 / 迷你音乐播放器3 / 4 /漓江烟雨 5 /6484452136 /2011.12.3 7 / 8 / 9 10 11 namespace UCCurrentTime12 13 public partial class UserControl1 : UserControl14 15 / 16 / 设置或获取当前播放进度条的宽度17 / 18 public int UCTime19 20 get return this.Width;

设置进度条长度7、由于去掉了默认的标题框所以自己添加了鼠标拖动事件鼠标拖动窗体代码 private void MiniMusicPlayer_MouseDown(object sender, MouseEventArgs e)if (e.Button = MouseButtons.Left)FormPositioX = e.X;FormPositioY = e.Y;private void MiniMusicPlayer_MouseMove(object sender, MouseEventArgs e)if (e.Button = MouseButtons.Left)this.Left += e.X - FormPositioX;this.Top += e.Y - FormPositioY;8、检测窗体位置，超出了屏幕范围会自动靠边处理窗体被拖动到屏幕外 1 private void MiniMusicPlayer_MouseUp(object sender, MouseEventArgs e)2 3 if (this.Left = 0)4 5 this.Left = 0;6 7 if (this.Top = ScreenEidth)15 16 this.Left = ScreenEidth - this.Width;17 18 if (this.Top + this.Height = ScreenGeight)19 20 this.Top = ScreenGeight - this.Height;21 22 9、组合键控制音量，默认音量为70控制音量代码 1 private void MiniMusicPlayer_KeyDown(object sender, KeyEventArgs e) /接收组合键调节音量2 3 if (e.Control) & (e.Alt) & (e.KeyCode = Keys.Up)4 5 if (axWMusicPlayer.settings.volume = 100)6 7 axWMusicPlayer.settings.volume = 100;8 9 else10 11 axWMusicPlayer.settings.volume += 5;12 13 14 if (e.Control & e.Alt & (e.KeyCode = Keys.Down)15 16 if (axWMusicPlayer.settings.volume = 0)17 18 axWMusicPlayer.settings.volume = 0;19 20 else21 22 axWMusicPlayer.settings.volume -= 5;23 24 25 10、跟据点击喜爱次数填充播放列表按喜爱次数自动填充播放列表 1 / 2 / 填充播放列表3 / 4 protected void FillCurrenrList()5 6 XmlDocument doc = new XmlDocument();7 doc.Load(xmlfile);8 if (doc.SelectSingleNode(MusicList).ChildNodes.Count != 0)9 10 XmlNodeList NodeList = doc.SelectSingleNode(MusicList).ChildNodes;11 string musiclist = new stringdoc.SelectSingleNode(MusicList).ChildNodes.Count;
