想给控件设置个圆形图片，代码如下：

 

​
 <Setter Property="Icon">
        <Setter.Value>
                <Image Source="/WpfApp1;component/Resource/1.ico" Width="16" Height="16"/>
        </Setter.Value>
    </Setter>

​

报错，提示   expected type is ‘geometry’, actual type is ‘image’

改成如下：

      <Setter Property="Icon">
            <Setter.Value>
                <EllipseGeometry Center="40,50" RadiusX="20" RadiusY="20"></EllipseGeometry>
            </Setter.Value>
        </Setter>
