其实很早就有这个想法了，不求界面多么华丽，只求功能实现，想来也不会很难，音乐播放器无非也就是些IO的操作，我写的山寨音乐播放器暂不支持在线播放，如果要播放的话，要将音乐文件下载到本地，通过IO操作读入程序中来，废话不多说了，界面如下（参考了传智播客蒋坤老师的相关课程）：
一些变量的定义及含义：
string temp1 = null; string temp2 = null; //设置添加曲目的路径 string strSearchPath; //定时退出的时间 int iSecond; bool IsVisible = false; //存放选择歌曲全路径 ListstrFullPath = new List (); //存放整理后的歌词 string[] sLrc = null; //存放搜索歌曲的全路径 List strSearchLst = new List ();
1.加载文件（“打开”按钮）
1 private void BtnOpen_Click(object sender, EventArgs e) 2 { 3 #region 加载播放列表，并开始播放 4 using (OpenFileDialog ofd=new OpenFileDialog()) 5 { 6 //从配置文件读取歌曲所在路径 7 ofd.InitialDirectory = ConfigurationManager.AppSettings["FilePath"]; 8 ofd.Title = "加载音乐文件"; 9 ofd.Multiselect = true;10 ofd.Filter = "音乐文件(*.mp3)|*.mp3|其他格式(*.avi)|*.avi|所有文件(*.*)|*.*";11 int n = -1;12 13 if (ofd.ShowDialog() == DialogResult.OK)14 {15 string[] strFullName = ofd.FileNames;16 if (strFullName.Length > 0)17 {18 for (int i = 0; i < strFullName.Length; i++)19 {20 if (!strFullPath.Contains(strFullName[i]))21 {22 strFullPath.Add(strFullName[i]);23 //F:\音乐\Beyond-海阔天空.mp324 string[] str = strFullName[i].Split('\\');25 lbSongsList.Items.Add(str[str.Length - 1]);26 PlaySongs(); 27 }28 else29 {30 //包含该歌曲31 if (MessageBox.Show("播放列表中已经包含该歌曲，现在播放吗？","提示",MessageBoxButtons.OKCancel)==DialogResult.OK)32 {33 string s = ofd.FileName;34 for (int j = 0; j < strFullPath.Count; j++)35 {36 if (strFullPath[j] == s)37 {38 n = j;39 break;40 }41 } 42 }43 else44 {45 return;46 }47 }48 }49 50 if (n != -1)51 {52 PlaySongs(n);53 } 54 }55 }56 }57 #endregion58 } PlaySongs()方法的定义如下：
1 ///2 /// 默认播放方法 3 /// 4 private void PlaySongs() 5 { 6 PlaySongs(0); 7 } 8 9 ///10 /// 播放方法11 /// 12 /// 13 private void PlaySongs(int i)14 {15 lbLrc1.Text = "";16 lbLrc2.Text = "";17 lbLrc3.Text = "";18 sLrc = null;19 20 if (i!=-1)21 {22 timer1.Enabled = true;23 axWindowsMediaPlayer1.URL = strFullPath[i];24 lbSongsList.SelectedIndex = i;25 this.Text = "当前播放曲目：" + lbSongsList.SelectedItem.ToString();26 axWindowsMediaPlayer1.Ctlcontrols.play();27 LoadLrc(axWindowsMediaPlayer1.URL);28 }29 30 if (lbSongsList.Items.Count>0)31 {32 groupBox1.Enabled = true;33 txtSelect.Enabled = true;34 BtnSelect.Enabled = true;35 BtnClear.Enabled = true;36 temp1 = lbSongsList.SelectedItem.ToString();37 lbMsg.Text = "当前列表共有歌曲" + strFullPath.Count + "首歌，当前播放曲目为：" + lbSongsList.SelectedItem.ToString();38 }39 }
LoadLrc()是加载歌词文件的方法，定义如下：
1 ///2 /// 加载歌词 3 /// 4 /// 5 private void LoadLrc(string p) 6 { 7 //F:\音乐\Beyond-光辉岁月(国语版).mp3 8 string[] strLrcLines; 9 int k = p.LastIndexOf('.');10 string sMusicLrc = p.Substring(0,k) + ".lrc";11 12 if (File.Exists(sMusicLrc))13 {14 #region 废弃15 //Encoding codeType = GetFileEncodingTye(sMusicLrc);16 //if (codeType.BodyName=="UTF8")17 //{18 // strLrcLines = File.ReadAllLines(sMusicLrc, Encoding.UTF8);19 // SelectLrc(strLrcLines);20 //}21 //else if (codeType.BodyName=="gb2312")22 //{23 // strLrcLines = File.ReadAllLines(sMusicLrc, Encoding.Default);24 // SelectLrc(strLrcLines); 25 //}26 //else27 //{28 // strLrcLines = File.ReadAllLines(sMusicLrc, Encoding.Default);29 // SelectLrc(strLrcLines);30 //} 31 #endregion32 33 strLrcLines = File.ReadAllLines(sMusicLrc, Encoding.UTF8);34 SelectLrc(strLrcLines);35 }36 else37 {38 lbLrc2.Text = "--该歌词未找到--";39 strLrcLines = null;40 }41 }
其中，加载歌词文件，涉及到歌词的整理，定义方法为SelectLrc()，定义如下：
1 ///2 /// 整理歌词文件 3 /// 4 /// 5 private void SelectLrc(string[] strLrcLines) 6 { 7 ListsTemp = new List (); 8 //[00:33.28]在他生命里仿佛带点唏嘘 9 if (strLrcLines.Length>0)10 {11 for (int i = 0; i < strLrcLines.Length; i++)12 {13 string[] s1 = strLrcLines[i].Split(new char[] { '[', ']' }, StringSplitOptions.RemoveEmptyEntries);14 for (int j = 0; j < s1.Length; j++)15 {16 if (s1[j].Contains(':'))17 {18 sTemp.Add(s1[j] + "|" + s1[s1.Length - 1]);19 }20 }21 } 22 }23 sTemp.Sort();24 sLrc = sTemp.ToArray();25 }
下面就要将整理好的歌词文件和音乐播放同步了，使用的是timer控件，将其间隔时间设为1000（1秒钟触发一次），写其Tick事件：
1 #region 歌词显示 2 if (lbSongsList.SelectedIndex != -1) 3 { 4 #region 信息显示 5 temp1 = temp1.Length > 10 ? temp1.Substring(1) + temp1[0] : temp1; 6 lbName.Text = "歌名：" + temp1; 7 temp2 = temp2.Length > 15 ? temp2.Substring(1) + temp2[0] : temp2; 8 lbState.Text = "播放状态：" + temp2; 9 lbPosition.Text = "当前位置：" + axWindowsMediaPlayer1.Ctlcontrols.currentPositionString;10 lbTotalTime.Text = "总时长：" + axWindowsMediaPlayer1.currentMedia.durationString;11 if (axWindowsMediaPlayer1.settings.mute == true)12 {13 lbVol.Text = "音量：静音 ";14 }15 else16 {17 lbVol.Text = "音量：" + axWindowsMediaPlayer1.settings.volume.ToString();18 }19 #endregion20 21 if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsPlaying)22 {23 if (sLrc != null)24 {25 for (int i = 0; i < sLrc.Length - 1; i++)26 {27 //00:02.01|光辉岁月 (指定曲目) - Beyond28 if (string.Compare(axWindowsMediaPlayer1.Ctlcontrols.currentPositionString, sLrc[i]) > 0 && string.Compare(axWindowsMediaPlayer1.Ctlcontrols.currentPositionString, sLrc[i + 1]) < 0)29 {30 //if (i-1>0)31 //{32 // lbLrc1.Text = sLrc[i - 1].Split('|')[1];33 //}34 //else35 //{36 // lbLrc1.Text = "";37 //}38 lbLrc1.Text = i - 1 > 0 ? sLrc[i - 1].Split('|')[1] : "";39 lbLrc2.Text = sLrc[i].Split('|')[1];40 lbLrc3.Text = sLrc[i + 1].Split('|')[1];41 }42 43 if (string.Compare(axWindowsMediaPlayer1.Ctlcontrols.currentPositionString, sLrc[0]) < 0)44 {45 lbLrc1.Text = "";46 lbLrc2.Text = lbSongsList.SelectedItem.ToString();47 lbLrc3.Text = sLrc[1].Split('|')[1];48 }49 if (string.Compare(axWindowsMediaPlayer1.Ctlcontrols.currentPositionString, sLrc[sLrc.Length - 1]) > 0)50 {51 lbLrc1.Text = sLrc[sLrc.Length - 2].Split('|')[1];52 lbLrc2.Text = sLrc[sLrc.Length - 1].Split('|')[1];53 lbLrc3.Text = "";54 }55 }56 }57 }58 } 59 #endregion temp2存储的是播放状态，在播放器的StatusChange()事件中为其赋值。
1 void axWindowsMediaPlayer1_StatusChange(object sender, EventArgs e)2 {3 temp2 = axWindowsMediaPlayer1.status;4 } 接下来是播放控制区的功能实现（上一曲，下一曲，播放，暂停等功能）
1 private void BtnPause_Click(object sender, EventArgs e) 2 { 3 #region 控制播放/暂停功能 4 if (lbSongsList.Items.Count > 0) 5 { 6 if (BtnPause.Text == "暂停") 7 { 8 BtnPause.Text = "播放"; 9 axWindowsMediaPlayer1.Ctlcontrols.pause();10 }11 else if (BtnPause.Text == "播放")12 {13 BtnPause.Text = "暂停";14 BtnStop.Text = "终止";15 axWindowsMediaPlayer1.Ctlcontrols.play();16 }17 }18 #endregion19 } 1 private void BtnStop_Click(object sender, EventArgs e) 2 { 3 #region 控制终止功能 4 if (lbSongsList.Items.Count > 0) 5 { 6 if (BtnStop.Text == "终止") 7 { 8 BtnStop.Text = "取消终止"; 9 BtnPause.Text = "播放";10 axWindowsMediaPlayer1.Ctlcontrols.stop();11 }12 else if (BtnStop.Text == "取消终止")13 {14 BtnStop.Text = "终止";15 BtnPause.Text = "暂停";16 axWindowsMediaPlayer1.Ctlcontrols.play();17 }18 }19 #endregion20 } 1 private void BtnPrev_Click(object sender, EventArgs e) 2 { 3 #region 上一曲 4 //int j = lbSongsList.SelectedIndex; 5 //if (j!=-1&&lbSongsList.Items.Count>0) 6 //{ 7 // j = j == 0 ? strFullPath.Count - 1 : --j; 8 // PlaySongs(j); 9 //}10 11 int j = -1;12 string s = axWindowsMediaPlayer1.URL;13 14 if (strFullPath.Count > 0)15 {16 for (int i = 0; i < strFullPath.Count; i++)17 {18 if (strFullPath[i]==s)19 {20 j = i;21 break;22 }23 }24 25 if (j!=-1)26 {27 j = j == 0 ? strFullPath.Count - 1 : --j;28 PlaySongs(j);29 }30 }31 #endregion32 } 1 private void BtnNext_Click(object sender, EventArgs e) 2 { 3 #region 下一曲 4 //int j = lbSongsList.SelectedIndex; 5 //if (j!=-1&&lbSongsList.Items.Count>0) 6 //{ 7 // j = j == strFullPath.Count - 1 ? 0 : ++j; 8 // PlaySongs(j); 9 //}10 11 int j = -1;12 string s = axWindowsMediaPlayer1.URL;13 14 if (strFullPath.Count>0)15 {16 for (int i = 0; i < strFullPath.Count; i++)17 {18 if (strFullPath[i]==s)19 {20 j = i; break;21 }22 }23 24 if (j!=-1)25 {26 j = j == strFullPath.Count - 1 ? 0 : ++j;27 PlaySongs(j);28 }29 }30 #endregion31 } 控制音量：

1.调整字体字号：
1 private void BtnSetting_Click(object sender, EventArgs e) 2 { 3 //调整字体字号 4 using (FontDialog fd=new FontDialog()) 5 { 6 fd.Font = lbLrc2.Font; 7 if (fd.ShowDialog()==DialogResult.OK) 8 { 9 lbLrc2.Font = fd.Font;10 lbSongsList.Font = fd.Font;11 }12 }13 } 2.设置字体颜色：
1 private void BtnSetColor_Click(object sender, EventArgs e) 2 { 3 //设置字体颜色 4 using (ColorDialog cd=new ColorDialog()) 5 { 6 cd.Color = lbLrc2.ForeColor; 7 if (cd.ShowDialog()==DialogResult.OK) 8 { 9 lbLrc2.ForeColor = cd.Color;10 lbSongsList.ForeColor = lbLrc2.ForeColor;11 }12 }13 } 3.设置背景色:

1 private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e) 2 { 3 if (e.Button==MouseButtons.Left) 4 { 5 this.WindowState = FormWindowState.Normal; 6 //this.ShowInTaskbar = true; 7 notifyIcon1.Visible = false; 8 this.ShowInTaskbar = !notifyIcon1.Visible; 9 this.Activate();10 }11 } 5.定时退出的功能实现（为系统托盘的关联菜单功能），定义TimeOver(时间参数),方法：
1 private void TimeOver(int i)2 {3 iSecond = i * 60;4 IsVisible = true;5 } 并在Time控件中计时：
1 if (IsVisible) 2 { 3 if (iSecond >= 1) 4 { 5 lbShow.Visible = true; 6 iSecond--; 7 string s = ConvertTime(iSecond); 8 lbShow.Text = s + "后程序将退出"; 9 lbShow.ForeColor = Color.BlueViolet;10 lbShow.Font = new Font("微软雅黑", 12);11 }12 else13 {14 lbShow.Visible = false;15 BtnExit_Click(sender, e);16 }17 } 1 ///2 /// 时间转换方法 3 /// 4 /// 5 ///6 private string ConvertTime(int iSecond) 7 { 8 StringBuilder sb = new StringBuilder(); 9 10 if (iSecond/3600>=1)11 {12 int a = Convert.ToInt32(iSecond) / 3600;13 sb.Append(a + "时");14 int b = iSecond - a * 3600; //剩余秒数15 if (b/60>=1)16 {17 int c = Convert.ToInt32(b) / 60; //分钟数18 sb.Append(c + "分");19 int d = b - c * 60;20 if (d>0)21 {22 sb.Append(d + "秒");23 }24 }25 else26 {27 sb.Append(Convert.ToInt32(b) + "秒");28 }29 }30 else if (iSecond/60>=1)31 {32 int e=Convert.ToInt32(iSecond) / 60;33 sb.Append(e + "分");34 int f = iSecond - e * 60;35 if (f>0)36 {37 sb.Append(f + "秒");38 }39 }40 else 41 {42 sb.Append(iSecond+"秒");43 }44 return sb.ToString();45 }
当右击托盘时，显示此菜单（及最小化时在任务栏中不出现，点击此菜单“显示”时，显示主界面，托盘消失）：
1 private void toolStripMenuItem1_Click(object sender, EventArgs e)2 {3 this.WindowState = FormWindowState.Normal;4 //this.ShowInTaskbar = true;5 notifyIcon1.Visible = false;6 this.ShowInTaskbar = !notifyIcon1.Visible;7 this.Activate();8 }
