我要评论本文实例讲述了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。
