Answer 1

在 MSDN 上得到它

// Create a red rectangle that will be the target 
Rectangle myRectangle = new Rectangle();
myRectangle.Width = 200;
myRectangle.Height = 200;
Color myColor = Color.FromArgb(255, 255, 0, 0);
SolidColorBrush myBrush = new SolidColorBrush();
myBrush.Color = myColor;
myRectangle.Fill = myBrush;

// Add the rectangle to the tree.
LayoutRoot.Children.Add(myRectangle);

// Create a duration of 2 seconds.
Duration duration = new Duration(TimeSpan.FromSeconds(2));

// Create two DoubleAnimations and set their properties.
DoubleAnimation myDoubleAnimation1 = new DoubleAnimation();
DoubleAnimation myDoubleAnimation2 = new DoubleAnimation();

myDoubleAnimation1.Duration = duration;
myDoubleAnimation2.Duration = duration;

Storyboard sb = new Storyboard();
sb.Duration = duration;

sb.Children.Add(myDoubleAnimation1);
sb.Children.Add(myDoubleAnimation2);

Storyboard.SetTarget(myDoubleAnimation1, myRectangle);
Storyboard.SetTarget(myDoubleAnimation2, myRectangle);

// Set the attached properties of Canvas.Left and Canvas.Top
// to be the target properties of the two respective DoubleAnimations.
Storyboard.SetTargetProperty(myDoubleAnimation1, new PropertyPath("(Canvas.Left)"));
Storyboard.SetTargetProperty(myDoubleAnimation2, new PropertyPath("(Canvas.Top)"));

myDoubleAnimation1.To = 200;
myDoubleAnimation2.To = 200;

// Make the Storyboard a resource.
LayoutRoot.Resources.Add("unique_id", sb);

// Begin the animation.
sb.Begin();
