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
List<string> strFullPath = new List<string>();
//存放整理后的歌词
string[] sLrc = null;
//存放搜索歌曲的全路径
List<string> strSearchLst = new List<string>();

LoadLrc()是加载歌词文件的方法，定义如下：

6 {
7 File.Delete("music.txt");
8 }
9
10 for (int i = 0; i <= strFullPath.Count - 1; i++)
11 {
12 File.AppendAllText("music.txt", strFullPath[i] + "\r\n", Encoding.Default);
13 }
14 }
15 this.Close();
16 }
至此，音乐播放器的主要功能都已实现，下面是一些辅助功能的实现代码：
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 BtnBColor_Click(object sender, EventArgs e)
2 {
3 //设置背景色
4 using (ColorDialog cd = new ColorDialog())
5 {
6 cd.Color = lbLrc2.BackColor;
7 if (cd.ShowDialog() == DialogResult.OK)
8 {
9 lbSongsList.BackColor = cd.Color;
10 }
11 }
12 }
4.实现系统托盘的功能，使用到的是notifyIcon控件：
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 else
13 {
14 lbShow.Visible = false;
15 BtnExit_Click(sender, e);
16 }
17 }
1 /// <summary>
2 /// 时间转换方法
3 /// </summary>
4 /// <param name="iSecond"></param>
5 /// <returns></returns>
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 else
26 {
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 }
