如何在 WPF 中获取 UI 元素的旋转值 [英] How to get the rotation value of a UI Element in WPF

问题描述

我已经知道如何分配旋转值 (element.RenderTransform = new RotateTransform(x))，但是如何获取元素的旋转值?

I've figured out how to assign a rotation value (element.RenderTransform = new RotateTransform(x)), but how do I get the rotation value of the element?

例如，如果我想让一个 ui 元素与另一个 ui 元素具有相同的旋转角度，我该怎么做?

For example, if I wanted to make one ui element have the same rotation angle as another ui element, how would I do that?

推荐答案

您可以通过以下方式获取旋转值:

You can get the rotation value by doing:

RotateTransform rotation = element.RenderTransform as RotateTransform;
if (rotation != null) // Make sure the transform is actually a RotateTransform
{
    double rotationInDegrees = rotation.Angle;
    // Do something with the rotationInDegrees here, if needed...
}

如果你只想让另一个 UIelement 以同样的方式旋转，你可以只分配相同的变换:

If you want to just make another UIelement rotate in the same way, you can just assign the same transform:

element2.RenderTransform = element.RenderTransform;
