改变冻结物体的可见性？
我正在尝试优化我的 WPF/VB.net 程序，并且正在考虑冻结一些对象。然而，虽然我知道以任何方式动画的对象都不能被冻结，但我需要知道......您可以更改冻结对象的可见性吗？
谢谢你！
I'm trying to optimize my WPF/VB.net program, and I'm considering freezing some objects. However, while I know that an object that is animated in any way cannot be frozen, I need to know...can you change the visibility of a frozen object?
Thank you!

从概念上来说，冻结
Freezable对象会使其不可变，因此尝试写入任何可写属性都会引发异常，包括Visibility。但是，您可以通过将 Freezable 对象包含在不可冻结对象中来隐式影响它的状态。例如，您可以使用Grid或任何其他Panel作为包装器并切换容器的Visibility，它将影响看似不可变的内容间接冻结对象。话虽这么说，冻结并不能真正提高效率，除非您要复制该对象的大量副本。Freezing a
Freezableobject conceptually makes it immutable so an attempt to write to any writable properties should throw an exception, includingVisibility. You can however implicitly affect aFreezableobject's state by containing it in a non-freezable object. For example, you can use aGridor any otherPanelas a wrapper and toggle theVisibilityof the container and it will affect the seemingly immutable frozen object indirectly. That being said, freezing doesn't really buy you very much efficiency-wise unless you are making quite a lot of copies of the object.
