Event for when the number of displays changes in .NET?

I have a program that needs to update some internal data structures when the number of attached displays changes, like when you put your laptop into the docking station and your dual monit开发者_如何学编程ors comes to life.

Couple of questions in this regard:

• Is there such an event in .NET?
• If not, is there a windows message I can listen for?
• Will Screen.AllScreens be updated?
• Will it be updated before I catch the event? or after? or is that indeterminate?

If it matters, this is .NET 3.5 and C#.

Have you looked into SystemEvents.DisplaySettingsChanged Event:

Occurs when the user changes the display settings.

There's not much more information than this on the MSDN but it might be of some use.
