我想要更改矩形颜色,但是,颜色不会#39;要更改。哪里有问题?
ColorAnimation col = new ColorAnimation();
col.From = Colors.Aqua;
col.To = Colors.PaleGreen;
col.Duration = new Duration(TimeSpan.FromSeconds(1));
Storyboard zgo = new Storyboard();
Storyboard.SetTarget(col, c);
Storyboard.SetTargetProperty(col,
new PropertyPath(SolidColorBrush.ColorProperty));
zgo.Children.Add(col);
zgo.Begin();
这是XAML:
<Rectangle Name="rec"
Height="100" Width="200"
HorizontalAlignment="Left" VerticalAlignment="Top"
Stroke="Black"
MouseLeftButtonDown="rec_MouseLeftButtonDown">
<Rectangle.Fill>
<SolidColorBrush x:Name="c"></SolidColorBrush>
</Rectangle.Fill>
</Rectangle>

通过调用Animatable.BeginAnimation
直接运行动画:
var colorAnimation = new ColorAnimation(
Colors.Aqua, Colors.PaleGreen, TimeSpan.FromSeconds(1));
c.BeginAnimation(SolidColorBrush.ColorProperty, colorAnimation);
你仍然可以通过使用Rectangle作为动画的目标和Fill.Color
作为目标属性::
Storyboard storyboard = new Storyboard();
Storyboard.SetTarget(colorAnimation, rec);
Storyboard.SetTargetProperty(colorAnimation, new PropertyPath("Fill.Color"));
storyboard.Children.Add(colorAnimation);
storyboard.Begin();
