在.NET里,没有托管的音乐播放器,用API只能播放WAV格式,对于MP3等形式的音频文件,就要依赖于其他控件了,常用的就是
MediaPlayer。使用方法:
在工具箱上点右键,选择“选择项目(Choose
Items)”,切到COM选项卡,找到
Windows
Media
Player,
勾选,确定
在t工具箱上,把刚才加入的MediaPlayer控件,拖放到窗体上
代码:
WindowsMediaPlayer1.URL
=
"mp3文件路径,支持网络路径"
WindowsMediaPlayer1.Ctlcontrols.play
基本就OK了,至于其他的操作诸如下一曲上一曲暂停停止,直接看
WindowsMediaPlayer1.Ctlcontrols.
里面的方法吧。
给你我的程序,自己研究一下吧,我也不是很明白。

My.Computer.Audio.Play("SoundFile.wav")
SoundFile.wav是你要播放的声音文件的路径
