推荐答案

由于ContextAction是

Since a ContextAction is a MenuItem this is not possible. The MenuItem does not expose any (bindable) IsVisible property or alike.

一个变通的解决方法是，每当您确定需要显示或隐藏哪些内容时，都可以添加/删除上下文操作.或使用可用的IsEnabled属性.

A hacky workaround could be to add/remove context actions whenever you determine what needs to be shown or hidden. Or use the IsEnabled property that is available.
