首先建立类player。 public class Player
{
private AxWMPLib.AxWindowsMediaPlayer myPlayer;
private string[] playList;
private int numOfMusic;
private int currentPlay;
public int NumOfMusic
{
get
{
return numOfMusic;
}
}
public WMPLib.WMPPlayState playstate
{
get
{
return myPlayer.playState;
}
}
public string PlayList(int num)
{
return playList[num];
}
public Player(AxWMPLib.AxWindowsMediaPlayer mediaPlayer)
{
myPlayer = mediaPlayer;
playList = new string[1000];
numOfMusic = 0;
}
switch (type)
{
case 0:
currentPlay ++;
if(currentPlay > numOfMusic)return 0;
else return currentPlay;
case 1:
currentPlay ++;
if(currentPlay > numOfMusic) return 1;
else return currentPlay;
case 2:
return currentPlay;
case 3:
Random rdm = new Random(unchecked((int)DateTime.Now.Ticks));
currentPlay = rdm.Next() % numOfMusic;
if(currentPlay == 0) return numOfMusic;
else return currentPlay;
default:
return 0;
}
}
} Player类中包括一个windowsMediaPlayer对象myPlayer,一个存储播放列表的数组playlist,记录歌曲总数的numOfMusic,以及当前播放的歌曲对应列表中的序号currentplay； 另外有四个方法分别是Play,AddFile,DelFile,以及获得下次播放序号的NextPlay
分功能列出其他主要代码
添加单个歌曲 if(this.openFileDialog1.ShowDialog() == DialogResult.OK)
{
string path = this.openFileDialog1.FileName;
FileInfo f = new FileInfo(path);
MyPlayer.AddFile(f.FullName);
string STRFILE = Convert.ToString(MyPlayer.NumOfMusic);
for(int i = 1;i<=5-STRFILE.Length;i++)STRFILE+=’ ’;
STRFILE += f.Name;
this.listBox1.Items.Add(STRFILE);
} 添加一个文件夹及其所有子文件夹的歌曲
利用递归函数showfiles实现所有层歌曲都添加到歌曲列表中。
private void showfiles(string path,ListBox listBox1)
{
DirectoryInfo dir = new DirectoryInfo(path);
foreach(FileInfo f in dir.GetFiles("*.mp3"))
{
MyPlayer.AddFile(f.FullName);
}
foreach(DirectoryInfo f in dir.GetDirectories())
{
showfiles(f.FullName,listBox1);
} 删除和清空直接调用类Player中的AddFile和DelFile函数
