x:Nameis a special property. As a matter of fact it's not a property at all, it's an attribute that maps the name or id property of the element to x:Name. Binding only works when applied to a DependencyProperty, so it cannot work on x:Name. It must be set manually.
x:Name是一个特殊的属性。事实上，它根本不是一个属性，它是一个将元素的 name 或 id 属性映射到x:Name. 绑定仅在应用于 a 时才有效DependencyProperty，因此无法在x:Name. 必须手动设置。
If you want to distinguish between objects in runtime, you can set the Tagattribute, which tolerates everything.
如果你想在运行时区分对象，你可以设置Tag属性，它容忍一切。

You should use FrameworkElement.Tagproperty, according to MSDN
FrameworkElement.Tag根据 MSDN，您应该使用财产
FrameworkElement.Tag gets or sets an arbitrary object value that can be used to store custom information about this element.
FrameworkElement.Tag 获取或设置可用于存储有关此元素的自定义信息的任意对象值。
