播放器 musicplayer in silverlight

網上看了幾看文獻所寫的一個播放器,事先聲明很垃圾的.我純粹試試mediaelement而已.

mainpage.xaml

1. <UserControl x:Class="musicPlayer.MainPage"

6.     <Grid x:Name="LayoutRoot" ShowGridLines="True" Background="Black">


7.         <MediaElement x:Name="media" Source="HUMAN_TOUCH.mp3" AutoPlay="False"/>


8.  


9.         <StackPanel VerticalAlignment="Stretch">


10.             <Button Content="Play" x:Name="play" Click="play_Click" Margin="5" />


11.             <Button Content="Pause" x:Name="pause" Click="pause_Click" Margin="5" />


12.             <Button Content="Stop" x:Name="stop" Click="stop_Click" Margin="5" />


13.             <Button Content="Mute" x:Name="mute" Click="mute_Click" Margin="5" />


14.             <Slider Grid.Row="1" x:Name="vol" Minimum="0" Maximum="1" ValueChanged="vol_ValueChanged" Margin="5" />


15.         </StackPanel>        


16.     </Grid>


17. </UserControl>
