动态添加阴影效果到Silverlight边框？

Question

我想一个DropShadowEffect动态添加到我的Silverlight的边界，但无法弄清楚的C＃语法...

   <Border BorderThickness="1" 
         CornerRadius="5" 
         Background="{StaticResource PanelBackground}" 
         BorderBrush="{StaticResource PanelBorderBrush}" 
         HorizontalAlignment="Left" 
         VerticalAlignment="Top" 
         Margin="0,8,0,0" 
         Width="250"> 
        <Border.Effect> 
         <DropShadowEffect /> 
        </Border.Effect> 
       </Border> 

我可以创建边界精其与Border.Effect我有麻烦。

System.Windows.Media.Effects.DropShadowEffect dropShadowEffect = new System.Windows.Media.Effects.DropShadowEffect(); 
dropShadowEffect.Opacity = 0.25; 
dropShadowEffect.ShadowDepth = 5; 
dropShadowEffect.BlurRadius = 10; 
dropShadowEffect.Color = Colors.Black; 
this.image.Effect = dropShadowEffect;

和

<Border Name="border"> 
      <Border.Effect> 
       <DropShadowEffect/> 
      </Border.Effect> 
     </Border> 

    this.border.Effect = dropShadowEffect;
