exception - AxWindowsMediaPlayer播放歌曲

Question

我可以帮忙使用AxWindowsMediaPlayer播放音频文件吗？

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

末级

尝试访问任何对象属性或方法时出现以下错误:

An unhandled exception of type 'System.Windows.Forms.AxHost.InvalidActiveXStateException' occurred in AxInterop.WMPLib.dll

您需要注意

-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"

或像这样；

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