求助：修复WPF C#后台代码中Storyboard的图片双轴动画问题

你的代码核心问题是重复设置了Storyboard的TargetProperty——第二次设置TranslateTransform.YProperty时覆盖了第一次的XProperty配置，导致只有Y轴动画生效。

修正方案1：给单个动画绑定目标属性 #

将目标属性绑定到每个动画对象，而非整个Storyboard，避免覆盖：

DoubleAnimationUsingKeyFrames AnimateX = new DoubleAnimationUsingKeyFrames();
AnimateX.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(0))));
AnimateX.KeyFrames.Add(new EasingDoubleKeyFrame(80, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(3))));
// 给X轴动画单独设置目标
Storyboard.SetTargetName(AnimateX, translationName);
Storyboard.SetTargetProperty(AnimateX, new PropertyPath(TranslateTransform.XProperty));

DoubleAnimationUsingKeyFrames AnimateY = new DoubleAnimationUsingKeyFrames();
AnimateY.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(0))));
AnimateY.KeyFrames.Add(new EasingDoubleKeyFrame(34, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(3))));
// 给Y轴动画单独设置目标
Storyboard.SetTargetName(AnimateY, translationName);
Storyboard.SetTargetProperty(AnimateY, new PropertyPath(TranslateTransform.YProperty));

TransformGroup tg = new TransformGroup();
TranslateTransform translation = new TranslateTransform();
string translationName = "myTranslation";
RegisterName(translationName, translation);
tg.Children.Add(translation);
myImage.RenderTransform = tg;

Storyboard s = new Storyboard();
string storyboardName = "s";
Resources.Add(storyboardName, s);
s.Children.Add(AnimateX);
s.Children.Add(AnimateY);
s.Begin();

修正方案2：直接给属性启动动画（更简洁） #

如果不需要Storyboard的额外功能（如控制播放状态、绑定触发器），可以跳过Storyboard，直接给TranslateTransform的X/Y属性启动动画：

DoubleAnimationUsingKeyFrames AnimateX = new DoubleAnimationUsingKeyFrames();
AnimateX.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(0))));
AnimateX.KeyFrames.Add(new EasingDoubleKeyFrame(80, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(3))));

DoubleAnimationUsingKeyFrames AnimateY = new DoubleAnimationUsingKeyFrames();
AnimateY.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(0))));
AnimateY.KeyFrames.Add(new EasingDoubleKeyFrame(34, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(3))));

TranslateTransform translation = new TranslateTransform();
myImage.RenderTransform = translation;

// 直接启动X、Y轴动画
translation.BeginAnimation(TranslateTransform.XProperty, AnimateX);
translation.BeginAnimation(TranslateTransform.YProperty, AnimateY);
