ColorAnimation cannot be used to animate property Background due to incompatible type

6335 단어 objectborder
오늘 컨트롤 스타일을 작성할 때 다음과 같은 이상이 발생했습니다.
    ColorAnimation cannot be used to animate property Background due to incompatible type.
여기는 이상한 곳을 알리는 XAML 코드입니다.
  <ColorAnimation Storyboard.TargetName="border" 
         Storyboard.TargetProperty="Background"
         Duration="0" To="#FF6B6B6B">
           <ColorAnimation.EasingFunction
                <ExponentialEase Exponent="15" EasingMode="EaseOut"/>
           </ColorAnimation.EasingFunction>
   </ColorAnimation>
 




              ：ColorAnimation cannot be used to animate property Background due to incompatible type.


        ColorAnimation          ，           。


              ：  TargetProperty  (Border.Background).(SolidColorBrush.Color)       



  <ColorAnimation Storyboard.TargetName="border" 
         Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"
         Duration="0" To="#FF6B6B6B">
           <ColorAnimation.EasingFunction
                <ExponentialEase Exponent="15" EasingMode="EaseOut"/>
           </ColorAnimation.EasingFunction>
   </ColorAnimation>
  
물론 두 번째 솔루션은 다음과 같습니다.
    
<Storyboard>
     <ObjectAnimationUsingKeyFrames Storyboard.TargetName="border" 
                                    Storyboard.TargetProperty="Background">
            <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent" />
     </ObjectAnimationUsingKeyFrames>
</Storyboard>
