我的应用程序有一个自定义用户控件(带动画的椭圆。)在我的主窗口中,我同时使用了usercontrol和一个按钮
我需要在按下按钮时为控件设置动画:
private void button1_Click(object sender, RoutedEventArgs e)
{
for (int i = 0; i < 10; i++)
{
userControl11.BlueAnimate();
dowork1();
userControl11.RedAnimate();
dowork2();
}
}
在我的控件的xml中,我有以下定义:
<UserControl.Resources>
<Storyboard x:Name="Ellipse1Animation" x:Key="Ellipse1Animation">
<DoubleAnimation
x:Name="AnimacionEllipse"
Storyboard.TargetName="_Ellipse"
Storyboard.TargetProperty="Opacity"
From="0.0" To="1.0" Duration="0:0:1"
AutoReverse ="True"
RepeatBehavior="Forever"
/>
</Storyboard>
</UserControl.Resources>
userControl11.BlueAnimate();
具有以下代码(对于其他方法几乎相同;唯一的变化是偏色。)
Public Sub BlueAnimate()
Dim AnimJob As Action = Function()
Dispatcher.Invoke(DirectCast(
Function()
Dim sb As Storyboard = FindResource("Ellipse1Animation")
Dim Anim As DoubleAnimation = sb.Children(0)
_Ellipse.Fill = Brushes.Blue
Storyboard.SetTargetName(Anim, "_Ellipse")
sb.Begin()
End Function, Action))
End Function
Task.Factory.StartNew(AnimJob )
End Sub
当我投射userControl11.BlueAnimate
时,它不会改变。可视界面保持冻结状态,不起作用。有人可以帮忙吗?
感谢您的时间。
