vb.net 中 如何实现 播放mp3文件

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。

vb.net中编辑音乐播放器用什么控件添加音乐

需要用到COM控件，例如media player、Real player等，或者用 .NET 自带的类库 System.Media下面的 SoundPlayer来播放音乐

vb.net中如何播放声音，是要什么控件嘛？

My.Computer.Audio.Play("SoundFile.wav")

SoundFile.wav是你要播放的声音文件的路径

VB.net里面怎么添加音乐

给你个 很简单的

Public Class Form1

Private Declare Function mciExecute Lib "winmm.dll" (ByVal lpstrCommand As String) As Long

‘ 声明函数 mciexcute 加入库 winmm.all

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Call mciExecute("play E:\music\music\单身情歌.wma ")

'在 formload过程中 调用函数 mciexcute 里面 是 文件 路径

End Sub

End Class

vb.net怎么播放音乐文件

添加一个 WindowsMediaPlayer 控件 一句代码即可播放音乐 AxWindowsMediaPlayer1.URL = "音乐地址"
