自己动手写的音乐播放器

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>();

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）

在播放器退出时，将最新的播放列表文件更新到文件中：

 1 private void BtnExit_Click(object sender, EventArgs e)
 2         {
 3             if (strFullPath.Count > 0)
 4             {
 5                 if (File.Exists("music.txt"))
 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         }
View Code

 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         }
View Code

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         }
View Code

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         }
View Code

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         }
View Code

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         }
View Code

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             }
View Code
 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         }
View Code

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         }
View Code
