使用WPF在动画中按特定角度旋转圆

<Window x:Class="WpfApp.MainWindow"

        <Ellipse x:Name="circle" Width="100" Height="100" Fill="Blue"/>
    </Grid>

using System.Windows;
using System.Windows.Media.Animation;

namespace WpfApp
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            // 创建旋转动画
            DoubleAnimation rotateAnimation = new DoubleAnimation();
            rotateAnimation.From = 0;  // 起始角度
            rotateAnimation.To = 360;  // 终止角度
            rotateAnimation.Duration = new Duration(TimeSpan.FromSeconds(5));  // 动画持续时间
            rotateAnimation.RepeatBehavior = RepeatBehavior.Forever;  // 无限循环

            // 将动画应用于圆形元素
            circle.RenderTransformOrigin = new Point(0.5, 0.5);  // 设置旋转中心点
            circle.RenderTransform = new RotateTransform();  // 创建旋转变换
            circle.BeginAnimation(RotateTransform.AngleProperty, rotateAnimation);  // 应用动画
        }
    }
