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。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
