画像を回転させようとしていますが、次のフェーズのようにストーリーボードを使用したいので、時間に合わせて実行される複数のアニメーションを追加する必要があります。
私のコードは、次のようにボタンのクリックイベント内にあります。
//start the animation
DoubleAnimation animationRotation = new DoubleAnimation();
animationRotation.From = -17;
animationRotation.To = 17;
animationRotation.Duration = new Duration(TimeSpan.FromMilliseconds(NumericDisplay.Milliseconds));
animationRotation.RepeatBehavior = RepeatBehavior.Forever;
animationRotation.AccelerationRatio = 0.3;
animationRotation.DecelerationRatio = 0.3;
animationRotation.AutoReverse = true;
Storyboard storyboard = new Storyboard();
Storyboard.SetTarget(animationRotation, Arm);
Storyboard.SetTargetProperty(animationRotation,
new PropertyPath("(UIElement.RenderTransform).(TransformGroup.Children)[0].(RotateTransform.Angle)"));
storyboard.Children.Add(animationRotation);
// Add the storyboard to the tracking collection.
//this.Stostoryboards.Add(bomb, storyboard);
// Configure and start the storyboard.
this.BeginStoryboard(storyboard);
コードは警告なしにコンパイルされますが、クリックイベントはアニメーションを開始しません。

私は何が間違っているのですか?
