动态添加阴影效果到Silverlight边框？

Question

我想动态地将DropShadowEffect添加到我的Silverlight边框，但是无法弄清楚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>

我可以创建边框很好的边框。影响我遇到了麻烦。

保罗。

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;
