1、CD、VCD音频播放

首先需要添加Wiindows Media Player组件，方法：

（1）“工具箱”右键“选择项”。

（2）在弹出的“选择工具箱项”对话框中选择“COM组件”选项卡。

（3）在COM组件列表中选择Windows Media Player，单击确定，ok。

事例代码：

private void 选取文件_Click(object sender, EventArgs e)

{

this.optFile.ShowDialog();

this.axWindowsMediaPlayer1.newMedia(this.optFile.FileName);

}

private void 播放文件_Click(object sender, EventArgs e)

{

this.axWindowsMediaPlayer1.URL = this.optFile.FileName;

}

private void 停止_Click(object sender, EventArgs e)

{

this.axWindowsMediaPlayer1.close();

}

暂停： this.axWindowsMediaPlayer1.Ctlcontrols.pause();

继续播放：this.axWindowsMediaPlayer1.Ctlcontrols.play();

获取歌曲信息：

private WMPLib.WindowsMediaPlayerClass c;

private WMPLib.IWMPMedia m;

private void ButInfo_Click(object sender, EventArgs e)

{

if (this.optFile.FileName != "optFile")

{

c = new WMPLib.WindowsMediaPlayerClass();

m = c.newMedia(this.optFile.FileName);

MessageBox.Show("歌手名:" + m.getItemInfo("Author") + "/r/n" + "歌 名:" + m.getItemInfo("Title"));

}

}

2、MP3 、WAV播放

1）带记忆功能的MP3 播放器

具有带记忆功能只需要在程序退出时，将当前用户选择的文件保存到ini文件中就可以了。

如：在打开文件的同时写入到ini文件中：

string strpath;

public Form1() //构造函数

{

InitializeComponent();

strpath = System.Environment.CurrentDirectory;

}

private void button1_Click(object sender, EventArgs e)

{

this.openFileDialog1.FileName = "";

this.openFileDialog1.ShowDialog();

StreamWriter s = new StreamWriter(strpath + "//HyList.ini", true);

s.WriteLine(openFileDialog1.FileName);

s.Flush();

s.Close();

ShowWindows(openFileDialog1.FileName); //调用函数

}

public void ShowWindows(string fileName)

{

this.listBox1.Items.Add(fileName);

}

在打开窗体的时候加载ini文件中的数据：

private void Form1_Load(object sender, EventArgs e)

{

string str = Application.StartupPath;

StreamReader sr = new StreamReader(str + "//HyList.ini");

while (sr.Peek() >= 0)

{

string strk=sr.ReadLine();

if (strk!="")

listBox1.Items.Add(strk);

}

sr.Close();

}

播放选中文件：

private void button2_Click(object sender, EventArgs e)

{

if (listBox1.SelectedItems.Count > 0)

{

string strPath = listBox1.SelectedItem.ToString();

ShowPlay(strPath);

}

}

2）、自动播放的MP3播放器

（1）自动添加播放列表：

private void button1_Click(object sender, EventArgs e)

{

this.listBox1.Items.Clear();

if (this.folderBrowserDialog1.ShowDialog()==DialogResult.OK)

{

DirectoryInfo dir = new DirectoryInfo(folderBrowserDialog1.SelectedPath);

GetAllFiles(dir); //调用函数

}

}

public void GetAllFiles(DirectoryInfo dir)

{

this.listBox1.Items.Clear();

FileSystemInfo[] fileinfo = dir.GetFileSystemInfos(); //返回表示某个目录中所有文件和子目录的强类型System.IO.FileSystemInfo项的数组

foreach (FileSystemInfo i in fileinfo)

{

if (i is DirectoryInfo)

{

GetAllFiles((DirectoryInfo)i);

}

else

{

string str = i.FullName;

int b = str.LastIndexOf("//");

string strbbb = str.Substring(b + 1);

if (strbbb.Substring(strbbb.Length - 3) == "mp3")

{

this.listBox1.Items.Add(str.Substring(b + 1));

//添加列表

WC = new WMPLib.WindowsMediaPlayerClass();

MC = WC.newMedia(str);

this.axWindowsMediaPlayer1.currentPlaylist.appendItem(MC);

}

}

}

}

播放所有文件：

private void button2_Click(object sender, EventArgs e)

{

if (MC != null)

this.axWindowsMediaPlayer1.Ctlcontrols.play();

else

MessageBox.Show("请添加文件列表");

}

3、播放动画

1）播放Flash动画

首先需要计算机中有Flash插件，添加过程如下：

（1）选择“工具箱”，单击鼠标右键，在弹出的快捷菜单中选择“选择项”。

（2）弹出“选择工具箱项”对话框，选择“COM组件”选择卡。

（3）在COM组件列表中，单击[浏览]按钮，在对话框中选择“//SYSTEM32/Macromed/Flash/SWFLASH.OCX”.

打开文件事件：

try

{

openFileDialog1.Filter = "Flash文件(*.swf)|*.swf|所有文件(*.*)|*.*";

if (openFileDialog1.ShowDialog() == DialogResult.OK)

{

string MyFileName = openFileDialog1.FileName;

this.axShockwaveFlash1.Movie = MyFileName;

}

}

catch (Exception ey)

{

MessageBox.Show(ey.Message);

}

//播放

private void button6_Click(object sender, EventArgs e)

{

this.axShockwaveFlash1.Rewind();

this.axShockwaveFlash1.Play();

}

//第一帧

private void button3_Click(object sender, EventArgs e)

{

this.axShockwaveFlash1.Rewind();

}

//上一帧

private void button4_Click(object sender, EventArgs e)

{

this.axShockwaveFlash1.Back();

}

//下一帧

private void button5_Click(object sender, EventArgs e)

{

this.axShockwaveFlash1.Forward();

}

//停止

private void button2_Click(object sender, EventArgs e)

{

this.axShockwaveFlash1.Stop();

}

2）播放制作AVI播放器

需添加“COM组件”中“Microsoft Animation Control，Version 6.0”

主要方法： open（）方法，eg. this.axAnimation1.Open(Application.StartupPath + "//clock.avi");

stop（）方法，

Play（）方法，播放文件。参数this.axAnimation1.Play(播放次数, 播放开始帧, 播放结束帧);

4、播放Gif动画

Bitmap bitmap = new Bitmap(Application.StartupPath+"//1.gif");

bool current = false;

播放事件：

private void button1_Click(object sender, EventArgs e)

{

PlayImage();

ImageAnimator.Animate(bitmap, new EventHandler(this.OnFrameChanged));//播放

}

public void PlayImage()

{

if (!current)

{

ImageAnimator.Animate(bitmap, new EventHandler(this.OnFrameChanged));

current = true;

}

}

停止播放：

private void button2_Click(object sender, EventArgs e)

{

ImageAnimator.StopAnimate(bitmap, new EventHandler(this.OnFrameChanged));//停止

}
