C#、.NET迷你音乐播放器
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
1 /// <summary>
2 /// 迷你音乐播放器
3 /// <author>
4 ///<name>漓江烟雨</name>
5 ///<QQ>648445213</QQ>
6 ///<date>2011.12.3</date>
7 /// </author>
8 /// </summary>

10
11 namespace UCCurrentTime
12 {
13 public partial class UserControl1 : UserControl
14 {
15 /// <summary>
16 /// 设置或获取当前播放进度条的宽度
17 /// </summary>
18 public int UCTime
19 {
20 get { return this.Width; }
21 set
22 {
23 if (this.Width >= 16)
24 {
25 this.Width = value;
26 }
27 else
28 {
29 this.Width = value + 16;
30 }
31
32 }
33 }
34
35 /// <summary>
36 /// 设置或获取当前播放进度条左边背景图片
37 /// </summary>
38 public Image LeftBackImage
39 {
40 get { return picBoxLeft.BackgroundImage; }
41 set { picBoxLeft.BackgroundImage = value; }
42 }
43
44 /// <summary>
45 /// 设置或获取当前播放进度条右边背景图片
46 /// </summary>
47 public Image RightBackImage
48 {
49 get { return picBoxRight.BackgroundImage; }
50 set { picBoxRight.BackgroundImage = value; }
51 }
52
53 /// <summary>
54 /// 设置或获取当前播放进度条中间背景图片
55 /// </summary>
56 public Image MiddleBackImage
57 {
58 get { return picBoxMiddle.BackgroundImage; }
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++)
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 }
