本文实例讲述了C#定义的MP3播放类。分享给大家供大家参考。具体分析如下：
这里使用C#定义一个MP3播放类，将Mp3文件作为资源文件包含到项目中，就可以播放mp3了
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.InteropServices;
namespace Mp3Tool
{
public Class MP3Player
{
[DllImport ("winmm.dll")]
static extern Int32 mciSendString (String command,StringBuilder buffer, Int32 bufferSize, IntPtr hwndCallback);
/// <summary>
/// temporary repository of music files
/// </ summary>
private String m_musicPath = "";
/// <summary>
/// parent window handle
/// </ summary>
private IntPtr m_Handle;
/// <summary>
/// Create Mp3 player class
/// </ summary>
/// <PARAM name="music">embedded music file</ param>
/// <PARAM name="path">temporary music file path</ param>
/// <PARAM name="Handle">parent window handle</ param>
public MP3Player (Byte [] Music, String path, IntPtr Handle)
{
try
{
m_Handle = Handle;
m_musicPath = Path.Combine (path, "temp.mp3");
FileStream fs = new FileStream (m_musicPath, FileMode.Create);
fs.Write (Music, 0, music.Length);
fs.Close ();
}
catch (Exception)
{
}
}
/// <summary>
/// Create Mp3 player class
/// </ summary>
/// <PARAM name="musicPath">to play the mp3 file path</ param>
/// <PARAM name="Handle">parent window handle</ param>
public MP3Player(String musicPath, IntPtr Handle)
{
m_musicPath = musicPath;
m_Handle = Handle;
}
public MP3Player(Byte [] Music, IntPtr Handle) : this(Music, @"C:\Windows\",Handle)
{
}
public void Open (String path)
{
IF (path ! = "")
{
try
{
mciSendString ("Open " + path + " alias Media", null, 0, m_Handle);
mciSendString ("play Media", null, 0, m_Handle);
}
catch (Exception)
{
}
}
}
public void Open()
{
Open (m_musicPath);
}
void CloseMedia()
{
try
{
mciSendString ("Close ALL", null, 0, m_Handle);
}
catch (Exception)
{
}
}
}
}
调用方法：
private void Main()
{
//load music
MP3Player MP3 = new MP3Player (Properties.Resources.music, Handle);
//music start playing
mp3.Open ();
}
希望本文所述对大家的C#程序设计有所帮助。
