 1、控件旋转，可直接调用。需要将控件的名称，旋转的角度，时间等参数传进去。

        /// <summary>

        /// 控件绕中心旋转动画

        /// </summary>

        /// <param name="element">控件名</param>

        /// <param name="anglefrom">开始角度</param>

        /// <param name="angleto">结束角度</param>

        /// <param name="power">过渡强度1为不用过渡</param>

        /// <param name="time">持续时间，例如3秒： TimeSpan(0,0,3) </param>

        public void AngleEasingAnimationShow(UIElement element, double anglefrom, double angleto,int power,TimeSpan time)

        {

            RotateTransform angle = new RotateTransform();  //旋转

            element.RenderTransform = angle;

            //定义圆心位置

            element.RenderTransformOrigin = new System.Windows.Point(0.5, 0.5);

            //定义过渡动画,power为过度的强度

            EasingFunctionBase easeFunction = new PowerEase()

            {

                EasingMode = EasingMode.EaseInOut,

                Power = power

            };

            DoubleAnimation angleAnimation = new DoubleAnimation()

            {

                From = anglefrom,                                   //起始值

                To = angleto,                                     //结束值

                FillBehavior = FillBehavior.HoldEnd,

                Duration = time,                                 //动画播放时间

            };

            angle.BeginAnimation(RotateTransform.AngleProperty, angleAnimation);

        }
