首先将WindowStyle样式设置为none，AllowTransParency为True，BackGround为Transparent，OpacityMask为White

 WindowStyle="None" Background="Transparent" OpacityMask="White"  AllowsTransparency="True" ResizeMode="NoResize"

 

 其次将grid加一个boder，方便加圆角就可以了

<Border Background="White" Height="192" Width="169" BorderThickness="1" BorderBrush="red" CornerRadius="4,4,4,4" Name="top">

<Border.Effect>

<DropShadowEffect ShadowDepth="0" Color="White" BlurRadius="4"/>

</Border>
