我可以帮助您使用AxWindowsMediaPlayer播放音频文件。

我正在使用Visual Basic.net 2012 Ultimate。

这是我的代码:

Imports AxWMPLib

Public Class Form1

Public WithEvents MediaPlayerObject As AxWindowsMediaPlayer = New AxWindowsMediaPlayer

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    MediaPlayerObject = New AxWindowsMediaPlayer
    MediaPlayerObject.Ctlenabled = True
    MediaPlayerObject.URL = "C:\Users\Simon\Music\Music\CanLucidDream\108761__soundbytez__birds-late-morning.wav"
    MediaPlayerObject.Ctlcontrols.play()
End Sub

结束班

尝试访问任何对象属性或方法时出现以下错误:

  

AxInterop.WMPLib.dll中出现未处理的“System.Windows.Forms.AxHost.InvalidActiveXStateException”类型异常

你需要注意

-MediaPlayerObject.URL = "C:\Users\Simon\Music\Music\CanLucidDream\108761__soundbytez__birds-late-morning.wav"- 

应该是这样的;

MediaPlayerObject.URL = "C:\\\Users\\\Simon\\\Music\\\Music\\\CanLucidDream\\\108761__soundbytez__birds-late-morning.wav"

或者像这样;

MediaPlayerObject.URL = @"C:\Users\Simon\Music\Music\CanLucidDream\108761__soundbytez__birds-late-morning.wav"

在使用任何属性或方法之前,需要调用BeginInit()和EndInit()。

MediaPlayerObject.BeginInit()
MediaPlayerObject.EndInit()
MediaPlayerObject.CtlEnabled = True
