阅读Silverlight中的MP3标签属性

我知道它适用于在silverlight中读出MP3标签属性MP3V1。我知道它没有任何第三方模组。但是当我使用像微软这样的MP3工作流程时，我总是会在我的MP3文件中获得零属性的数量。阅读Silverlight中的MP3标签属性

如何解决？

示例项目：下载MP3演示从这里文件： http://www.file-upload.net/download-2617219/Elenor_techno.mp3.html

    </StackPanel> 
</Grid>

Partial Public Class MainPage 
Inherits UserControl 

Public Sub New() 
    InitializeComponent() 
End Sub 

Private Sub MainPage_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded 

End Sub 

Private Sub MediaHelper_CurrentStateChanged(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles MediaHelper.CurrentStateChanged 
    If Me.MediaHelper.Attributes.ContainsKey("Title") Then Me.txtTitle.Text = Me.MediaHelper.Attributes("Title") 
End Sub 

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click 
    Me.txtTitle.Text = "Loading mp3..." 

    Me.MediaHelper.Source = New Uri("http://dave-d.ch/database/music/public/1000036869_stefan%20lange%20koolja.mp3") 
    Me.MediaHelper.Play() 
End Sub 

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button2.Click

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button3.Click 
    Me.MediaHelper.Stop() 
End Sub

从任何人都不知道？ – Nasenbaer 2010-06-29 14:47:43

确定。我创建了我自己的类，现在我通过服务将MP3标签提交给Silverlight页面。但是我仍然对Silverlight标签阅读器不感兴趣。
