如何为边框提供外部发光效果？

<Grid Width="200" Height="200">
    <Grid.Background>
        <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.8" RadiusY="0.8">
            <RadialGradientBrush.GradientStops>
                <GradientStop Offset="0" Color="#FF123B5F" />
                <GradientStop Offset="1" Color="#FF001F31" />
            </RadialGradientBrush.GradientStops>
        </RadialGradientBrush>
    </Grid.Background>
    <Border Width="180" Height="180" Margin="10" Background="Transparent"
            BorderBrush="White" BorderThickness="1">
        <Border.BitmapEffect>
            <OuterGlowBitmapEffect GlowColor="White" GlowSize="3" Opacity="1" />
        </Border.BitmapEffect>
    </Border>
</Grid>

我试过这个但是没用

如何在WPF中获取控件的委托列表表单事件.

我尝试了以下代码,但它会将字段信息返回为null

TextBox cont = new TextBox();
cont.TextChanged += new TextChangedEventHandler(cont_TextChanged);
FieldInfo fi = cont.GetType().GetField("TextChanged", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField | BindingFlags.Public | BindingFlags.Static);
Delegate del = (Delegate)fi.GetValue(cont);
