1、CD、VCD音頻播放
首先需要添加Wiindows Media Player組件，方法：
（1）“工具箱”右鍵“選擇項”。
（2）在彈出的“選擇工具箱項”對話框中選擇“COM組件”選項卡。
（3）在COM組件列表中選擇Windows Media Player，單擊確定，ok。
事例代碼：
private void 選取文件_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();
}
暫停： this.axWindowsMediaPlayer1.Ctlcontrols.pause();
繼續(xù)播放：this.axWindowsMediaPlayer1.Ctlcontrols.play();
獲取歌曲信息：
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）帶記憶功能的MP3 播放器
具有帶記憶功能只需要在程序退出時，將當前用戶選擇的文件保存到ini文件中就可以了。
如：在打開文件的同時寫入到ini文件中：
string strpath;
public Form1() //構造函數(shù)
{
InitializeComponent();
strpath = System.Environment.CurrentDirectory;
}
private void button1_Click(object sender, EventArgs e)
{
this.openFileDialog1.FileName = "";
this.openFileDialog1.ShowDialog();
StreamWriter s = new StreamWriter(strpath + "http://HyList.ini", true);
s.WriteLine(openFileDialog1.FileName);
s.Flush();
s.Close();
ShowWindows(openFileDialog1.FileName); //調用函數(shù)
}
public void ShowWindows(string fileName)
{
this.listBox1.Items.Add(fileName);
}
在打開窗體的時候加載ini文件中的數(shù)據(jù)：
private void Form1_Load(object sender, EventArgs e)
{
string str = Application.StartupPath;
StreamReader sr = new StreamReader(str + "http://HyList.ini");
while (sr.Peek() >= 0)
{
string strk=sr.ReadLine();
if (strk!="")
listBox1.Items.Add(strk);
}
sr.Close();
}
播放選中文件：
private void button2_Click(object sender, EventArgs e)
{
if (listBox1.SelectedItems.Count > 0)
{
string strPath = listBox1.SelectedItem.ToString();
ShowPlay(strPath);
}
}
2）、自動播放的MP3播放器
（1）自動添加播放列表：
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); //調用函數(shù)
}
}
public void GetAllFiles(DirectoryInfo dir)
{
this.listBox1.Items.Clear();
FileSystemInfo[] fileinfo = dir.GetFileSystemInfos(); //返回表示某個目錄中所有文件和子目錄的強類型System.IO.FileSystemInfo項的數(shù)組
foreach (FileSystemInfo i in fileinfo)
{
if (i is DirectoryInfo)
{
GetAllFiles((DirectoryInfo)i);
}
else
{
string str = i.FullName;
int b = str.LastIndexOf("http://");
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("請?zhí)砑游募斜?);
}
3、播放動畫
1）播放Flash動畫
首先需要計算機中有Flash插件，添加過程如下：
（1）選擇“工具箱”，單擊鼠標右鍵，在彈出的快捷菜單中選擇“選擇項”。
（2）彈出“選擇工具箱項”對話框，選擇“COM組件”選擇卡。
（3）在COM組件列表中，單擊[瀏覽]按鈕，在對話框中選擇“//SYSTEM32/Macromed/Flash/SWFLASH.OCX”.
打開文件事件：
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();
}
//第一幀
private void button3_Click(object sender, EventArgs e)
{
this.axShockwaveFlash1.Rewind();
}
//上一幀
private void button4_Click(object sender, EventArgs e)
{
this.axShockwaveFlash1.Back();
}
//下一幀
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組件”中“Microsoft Animation Control，Version 6.0”
主要方法： open（）方法，eg. this.axAnimation1.Open(Application.StartupPath + "http://clock.avi");
stop（）方法，
Play（）方法，播放文件。參數(shù)this.axAnimation1.Play(播放次數(shù), 播放開始幀, 播放結束幀);
4、播放Gif動畫
Bitmap bitmap = new Bitmap(Application.StartupPath+"http://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
}
