2、代码讲解
全局变量：private SoundPlayer Player = new SoundPlayer();
private SoundPlayer SencondPlayer = new SoundPlayer();
Image[] image = new Image[500];//存放图片数组
private int Imagecount = 0;//计算背景图片数
private int order = 0;//存储图片总数
private int fileCount = 0;//数组中计算音乐文件数
private int fileCount1 = 0;//文件系数
string[] musicfile = new string[500];//存放音乐文件
int selectOne = 0;//双击事件选择的音乐的序号
static int stop = 2;//判断是暂停还是播放
static double CurrentPosition = 0;//获得文件播放的位置
static int State = 0;//当前状态等于时进行单曲循环，等于零的时候进行顺序播放, //当前状态等于时为随机播放//当前状态等于时为列表播放
OpenFileDialog openfile = new OpenFileDialog();//打开本地磁盘对话框
添加音乐文件
private void 添加文件ToolStripMenuItem1_Click(object sender, EventArgs e)
{
fileCount1++;
openfile.Filter = \"|*.mp3\";
openfile.Multiselect = true;//支持多行文件
try
{
if (DialogResult.OK == openfile.ShowDialog())
{
musicfile[fileCount] = openfile.FileName;
FileInfo fileinfo = new FileInfo(musicfile[fileCount]);
//FileInfo类是将文件去相对路径
string filename = fileCount1.ToString() + \"_\" + fileinfo.Name;//使音乐名前加序号并只取文件名
this.listBox1.Items.Add(filename);//将文件多行显示在列表中
this.musicname.Text = fileinfo.Name;
PlayAndStop(fileCount); //启动MP3播放器
fileCount++;
}
}
catch (Exception)
{
MessageBox.Show(musicfile[fileCount].ToString());
}
}
添加音乐文件夹
private void 添加文件夹ToolStripMenuItem1_Click(object sender, EventArgs e)
{
FolderBrowserDialog folder = new FolderBrowserDialog();//文件夹初始化
folder.ShowDialog();
string[] file = Directory.GetFiles(folder.SelectedPath.ToString(),
\"*.MP3\");//使用数组存得到的文件
int fileName = 0;
try
{
{
fileCount1++;
musicfile[fileCount] = file[fileName];
fileName++;
fileCount++; 文件名
}
foreach (string Music in file)
FileInfo f = new FileInfo(file[fileName]);//读取文件
//数组存文件数
string total = fileCount1.ToString() + \"_\" + f.Name;//f.Name只取f中的this.listBox1.Items.Add(total);
}
catch (Exception)
{
MessageBox.Show(\"输入的音乐总数超出！\");
}
}
添加背景图片
private void 添加背景图片ToolStripMenuItem1_Click(object sender, EventArgs e)
{
FolderBrowserDialog folder = new FolderBrowserDialog();
folder.ShowDialog();
string[] BGfile = Directory.GetFiles(folder.SelectedPath.ToString(), \"*.jpg\");
foreach (string pic in BGfile)
{
image[order] = Image.FromFile(pic);
order++;
}
this.timer1.Enabled = true;//启动定时器
}
定时器
private void timer1_Tick(object sender, EventArgs e)
{
this.BGpicture.Image = image[Imagecount];
if (Imagecount >= order-1)
{
Imagecount = 0;
}
else
{
Imagecount++;
}
}
退出播放器
private void 退出ToolStripMenuItem1_Click(object sender, EventArgs e)
{
this.Close();
}
MP3音乐播放器 播放功能
//播放MP3文件
private void PlayAndStop(int fileCount)
{
try
{
stop = 3;
this.PlayOrStop.Text = \"暂停\";
FileInfo f = new FileInfo(musicfile[fileCount]);
this.musicname.Text = f.Name.ToString();//得到正在播放的音乐名
listBox1.SelectedIndex = fileCount;//自动选中跳转的文件
axWindowsMediaPlayer1.URL = musicfile[fileCount];
axWindowsMediaPlayer1.Ctlcontrols.play();
}
catch (Exception)
{
return;
}
}
a.单曲循环
private void 单曲循环ToolStripMenuItem1_Click(object sender, EventArgs e)
{
CurrentPosition = axWindowsMediaPlayer1.Ctlcontrols.currentPosition;//得到正在播放的位
axWindowsMediaPlayer1.Ctlcontrols.currentPosition
=
CurrentPosition;//接着停止的位置继续播放
State = 1;
axWindowsMediaPlayer1.settings.setMode(\"loop\", true);
}
b.顺序循环
private void 顺序播放ToolStripMenuItem1_Click(object sender, EventArgs e)
{
State = 0;
}
c.列表播放
private void 列表循环ToolStripMenuItem1_Click(object sender, EventArgs e)
{
State = 3;
}
d.随机播放
private void 随机播放ToolStripMenuItem1_Click(object sender, EventArgs e)
{
State = 2;
}
调用播放模式的事件
//改变播放状态，当音乐一首播放完后转入下一首，有线程调用
private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
Thread thread = new Thread(new ThreadStart(PlayThread));
//顺序播放
if
(axWindowsMediaPlayer1.playState==WMPLib.WMPPlayState.wmppsMediaEnded && State == 0)
{
try
{
if (selectOne > fileCount-2)
{
selectOne = 0;
thread.Start();
}
else
{
selectOne++;
thread.Start();
}
}
catch (Exception)
{
return;
}
}
//随机播放
try
{
if (axWindowsMediaPlayer1.playState WMPLib.WMPPlayState.wmppsMediaEnded && State == 2)
{
Random Num = new Random();
int Sum = Num.Next(0, fileCount);
FileInfo f = new FileInfo(musicfile[Sum]);
this.musicname.Text = f.Name;
selectOne = Sum;
thread.Start();
==
}
}
catch (Exception)
{
return;
}
//列表播放
try
{
if (axWindowsMediaPlayer1.playState WMPLib.WMPPlayState.wmppsMediaEnded && State == 3)
{
if (selectOne > fileCount - 2)
{
==
selectOne = 0;
}
else
{
selectOne++;
thread.Start();
}
}
}
catch (Exception)
{
return;
}
}
调用线程
private void PlayThread()
{
PlayAndStop(selectOne)；调用音乐播放功能
}
制作界面透明功能
//透明度%
private void toolStripMenuItem7_Click(object sender, EventArgs e)
{
this.Opacity = 0.1;
}
//透明度%
private void toolStripMenuItem8_Click(object sender, EventArgs e)
{
this.Opacity = 0.3;
}
//透明度%
private void toolStripMenuItem9_Click(object sender, EventArgs e)
{
this.Opacity = 0.5;
}
//透明度%
private void toolStripMenuItem10_Click(object sender, EventArgs e)
{
this.Opacity = 0.7;
}
//透明度%
private void toolStripMenuItem11_Click(object sender, EventArgs e)
{
this.Opacity = 0.9;
}
//不透明
private void 不透明ToolStripMenuItem1_Click(object sender, EventArgs e)
{
this.Opacity = 1.0;
}
界面设置
private void 迷ToolStripMenuItem_Click(object sender, EventArgs e)
{
Color color = Color.LightGoldenrodYellow;
this.musicname.BackColor = color;
this.label1.BackColor = color;
this.listBox1.BackColor = color;
this.Up.BackColor = color;
this.PlayOrStop.BackColor = color;
this.Down.BackColor = color;
this.Stop.BackColor = color;
this.MusicText.BackColor = color;
this.menu.BackColor = color;
this.statusStrip1.BackColor = color;
}

try
{
if (selectOne < fileCount-1)
{
selectOne++;
PlayAndStop(selectOne);

else
{
selectOne--;
PlayAndStop(selectOne);
}
}
catch (Exception)

return;
}
}
播放或暂停
private void PlayOrStop_Click(object sender, EventArgs e)
{
try
{
if (stop % 2 == 0)//判断播放或暂停
{
this.PlayOrStop.Text = \"暂停\";
selectOne = this.listBox1.SelectedIndex;
FileInfo f = new FileInfo(musicfile[selectOne]);
this.musicname.Text = f.Name;
string playUrl = musicfile[selectOne];
axWindowsMediaPlayer1.URL = playUrl;
axWindowsMediaPlayer1.Ctlcontrols.currentPosition CurrentPosition;
stop = stop + 1;//当前stop = 3；为暂停状态
axWindowsMediaPlayer1.Ctlcontrols.play();
CurrentPosition = 0;
}
else
{
this.PlayOrStop.Text = \"播放\";
=
CurrentPosition
axWindowsMediaPlayer1.Ctlcontrols.currentPosition;
=
axWindowsMediaPlayer1.Ctlcontrols.pause();
stop = stop - 1;//当前stop = 2；为开始状态
}
}
catch (Exception)
{
return;
}

stop = 2;
}
双击播放音乐
//双击事件
private void listBox1_DoubleClick(object sender, EventArgs e)
{
try
{
if (listBox1.SelectedIndex < 0)//listBox1.SelectedIndex 选择的对象
selectOne = 1;
else
selectOne = listBox1.SelectedIndex ;
if (listBox1.Items.Count < 0)//listBox1.Items.Count listbox中文件的数
listBox1.SelectedIndex = 0;
PlayAndStop(selectOne);
}
catch (Exception)
{
