FrameworkElement Extensions 为 FrameworkElement 提供了一种简单的绑定实际尺寸的方式，扩展利用 EnableActualSizeBinding 来指定是否允许实时绑定实际尺寸中的 ActualWidth...获取到的 ActualHeight 和 ActualWidrh 一直都是变为 False 时最后一个值，不管尺寸怎么改变都不会被更新和监听； 而通过扩展设置的绑定，和直接设置 ActualHeight 和 ActualWidth...= baseElement.ActualWidth) { SetActualWidth(baseElement, baseElement.ActualWidth); }...} 代码简单分析如上，大家在实际项目中可以对这个类进行扩展，比如把 Opacity，Color 等也作为可以实时绑定的值，实现方式和 ActualHeight ActualWidth 很类似，大家可以自行扩展...调用示例 我们创建了三个 Rectangle，第一个是绑定目标，第二和第三个去绑定第一个的实际尺寸；可以看到因为第二个红色矩形使用 ActualHeight 和 ActualWidth 直接进行绑定，所以并没有绑定到正确的值

PointerPoint point = e.GetCurrentPoint(btn); 这样point.Position.X就是移动的左边 我们可以通过x += point.Position.X - btn.ActualWidth.../ 2.0; 这是因为btn.ActualWidth / 2.0不用的话会是控件的左上角。...double y = (double)btn.GetValue(Canvas.TopProperty); x += point.Position.X - btn.ActualWidth...double y = (double)btn.GetValue(Canvas.TopProperty); x += point.Position.X - btn.ActualWidth

同时无法获得 ActualHeight 和 ActualWidth 的值。 在 Loaded 的时候，可以获得属性的值，而且可以获得 ActualHeight 和 ActualWidth 的值。
