您好scocia888，

您可以尝试以下代码：

 <网格和GT; 
< Border 
 BorderBrush =" Black" 
 BorderThickness =" 1,1,1,1" 
 CornerRadius =" 140,140,​​140,​​140"> 
< Border.Effect> 
< DropShadowEffect /> 
< /Border.Effect> 

< Border.Background> 
< ImageBrush ImageSource =" /Photo/1.jpg" /&GT; 
< /Border.Background> 
< / Border> 
< / Grid> 

***的问候，

Cherry

I have the following window code which has a circular border within a transparent square window giving the effect of a circular window. How do I get a Circular drop shadow which is effectively an offset of the circle towards the bottom right. I have tried all sorts of dropShadow effects on the borders but unable to get a circular drop shadow.

Many thanks

Hi scocia888,

You can try the following code:

  <Grid>
        <Border
            BorderBrush="Black"
            BorderThickness="1,1,1,1"
            CornerRadius="140,140,140,140">
            <Border.Effect>
                <DropShadowEffect />
            </Border.Effect>

            <Border.Background>
                <ImageBrush ImageSource="/Photo/1.jpg" />
            </Border.Background>
        </Border>
    </Grid>

Best Regards,

Cherry
