26                 }
27                 else

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++)
22                 {
23                     string[] hh = musiclist[i].Split(';');
24                     musiclist2[i, 0] = hh[0];
25                     musiclist2[i, 1] = hh[1];
26                 }
27
28                 string temp;
29                 for (int i = 0; i < num - 1; i++) //按点击次数冒泡排序，排序后的数组添加到axWMusicPlayer.currentPlaylist
30                 {
31                     for (int j = 0; j < num - 1 - i; j++)
32                     {
33                         if (Convert.ToInt32(musiclist2[j, 1]) < Convert.ToInt32(musiclist2[j + 1, 1]))
34                         {
35                             temp = musiclist2[j, 1];
36                             musiclist2[j, 1] = musiclist2[j + 1, 1];
37                             musiclist2[j + 1, 1] = temp;
38
39                             temp = musiclist2[j, 0];
40                             musiclist2[j, 0] = musiclist2[j + 1, 0];
41                             musiclist2[j + 1, 0] = temp;
42                         }
43                     }
44                 }
45
46                 for (int i = 0; i < num; i++) //填充播放列表47                 {
48                     axWMusicPlayer.currentPlaylist.appendItem(axWMusicPlayer.newMedia(musiclist2[i, 0]));
49                 }
50             }
51         }
