How do I tell if a PictureBox's Image has changed?

原文 2011-07-20 15:42:38 5 1 c#/ .net/ picturebox

Apparently, the PictureBox class does not offer an event when its Image property is set. Is there a way to still catch such a change, possibly by subclassing?

You could subclass it and hide the base class' Image property , providing your own which raised an event in the property setter ( set ) if the value is different.
