闲来没事自己做了一个基于WindowsMediaPlayer的迷你音乐播放器，界面如下图

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                 try
 6                 {
 7                     DateTime time = DateTime.Parse(关机时间toolStripTextBox.Text);
 8                     TimeSpan span = new TimeSpan(time.Hour, time.Minute, 0);
 9                     if (span.CompareTo(new TimeSpan(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                         else
19                         {
20                             return;
21                         }
22                     }
23                     if (span.CompareTo(new TimeSpan(DateTime.Now.Hour, DateTime.Now.Minute, 0)) < 0) //过去关机时间
24                     {
25                         MessageBox.Show("此时间已是过去时间，设定无效", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
26                         return;
27                     }
28                     if (span.CompareTo(new TimeSpan(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                 catch
42                 {
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             try
 9             {
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node
11                     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

21             set 
22             {
23                 if (this.Width >= 16)
24                 {

26                 }
27                 else
28                 {
29                     this.Width = value + 16;
30                 }
31

39         {
40             get { return picBoxLeft.BackgroundImage; }
41             set { picBoxLeft.BackgroundImage = value; } 
42         }
43 
44         /// <summary>

47         public Image RightBackImage 
48         {
49             get { return picBoxRight.BackgroundImage; }
50             set { picBoxRight.BackgroundImage = value; } 
51         }

59             set { picBoxMiddle.BackgroundImage = value; } 
60         }
61         public UserControl1()
62         {
63             InitializeComponent();
64 
65             picBoxLeft.Size = new Size(8, 10);  //左边
66             picBoxRight.Size = new Size(8, 10); //右边
67             picBoxMiddle.Size = new Size(0, 10); //中间
68 
69             picBoxLeft.Dock = DockStyle.Left;
70             picBoxRight.Dock = DockStyle.Right;
71             picBoxMiddle.Width = this.Width - 16;
72             picBoxMiddle.Location = new Point(8, 0);
73 
74             this.BackColor = Color.Transparent;
75             picBoxLeft.BackColor = Color.Transparent;
76             picBoxRight.BackColor = Color.Transparent;
77             picBoxMiddle.BackColor = Color.Transparent;
78 
79             picBoxLeft.BackgroundImage = LeftBackImage;
80             picBoxRight.BackgroundImage = RightBackImage;
81             picBoxMiddle.BackgroundImage = MiddleBackImage;
82         }
83 
84         private void UserControl1_SizeChanged(object sender, EventArgs e)
85         {
86             this.Size = new Size(UCTime, 10);
87             picBoxMiddle.Width = this.Width - 16;
88         }
89     }
90 }

　　timer_tick事件

timer_tick事件代码

 1 private void timer1_Tick(object sender, EventArgs e)
 2         {
 3             try
 4             {
 5                 if (axWMusicPlayer.currentMedia != null)
 6                 {
 7                     if (axWMusicPlayer.currentMedia.name.Length > 9)
 8                     {
 9                         lblMusicName.Text = axWMusicPlayer.currentMedia.name.Substring(0, 9) + "...";
10                     }
11                     else
12                     {
13                         lblMusicName.Text = axWMusicPlayer.currentMedia.name;
14                     }
15                     lblcurrenttime.Text = axWMusicPlayer.Ctlcontrols.currentPositionString + " / " + axWMusicPlayer.currentMedia.durationString;
16                     UCcurrenttime = Convert.ToInt32(axWMusicPlayer.Ctlcontrols.currentPosition / axWMusicPlayer.currentMedia.duration * 170);
17                     if (UCcurrenttime <= 16)
18                     {
19                         UCcurrenttime = 16;
20                     }
21                     this.userControl11.Width = UCcurrenttime;
22                 }
23             }
24             catch
25             {
26                 return;
27             }
28         }

　　this.userControl11.Width = UCcurrenttime; 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 <= 0)
 8             {
 9                 this.Top = 0;
10             }
11 
12             int ScreenEidth = Screen.GetWorkingArea(this).Width; //获得屏幕的宽
13             int ScreenGeight = Screen.GetWorkingArea(this).Height; //获得屏幕的高
14             if (this.Left + this.Width >= 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                 else
10                 {
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                 else
21                 {
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 /// <summary>
 2 ///  填充播放列表
 3 /// </summary>
 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 string[doc.SelectSingleNode("MusicList").ChildNodes.Count]; //每条MusicProperty组成一维数组
12                 int num = 0;
13                 foreach (XmlNode node in NodeList)
14                 {
15                     XmlElement element = (XmlElement)node;
16                     musiclist[num] = element.GetAttribute("MusicUrl") + ";" + element.GetAttribute("LikeCount");
17                     num++;
18                 }
19 
20                 string[,] musiclist2 = new string[num, 2]; //将一维数组分割为二维数组：MusicUrl、LikeCount
21                 for (int i = 0; i < num; i++)
