Freezable.Changed Event


在修改 Freezable 或其包含的对象时发生。Occurs when the Freezable or an object it contains is modified.

 event EventHandler ^ Changed;
public event EventHandler Changed;
member this.Changed : EventHandler 
Public Custom Event Changed As EventHandler 


如果在无法修改当前对象时尝试添加或删除事件处理程序(当 trueIsFrozen 属性时),则会引发异常。If you attempt to add or remove event handlers when the current object is not modifiable (when the IsFrozen property is true), an exception is thrown.
