本篇章节讲解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,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,m_Handle);
          mciSendString ("play Media",m_Handle);
        }
        catch (Exception)
        {
        }
      }
    }
    public void Open()
    {
      Open (m_musicPath);
    }
    void CloseMedia()
    {
      try
      {
        mciSendString ("Close ALL",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。
