Programmatically Lock The Screen

Question

How do I programmatically lock the screen of the iPhone using C#?

Answer 1

Quick answer

Apple does not allow you to do so (it's not a C# limitation).

Longer answer

There's a private GSEventLockDevice API to do so - but it would prevent your application to be on the appstore (Apple will refuse it because of the private API). Also it seems it is not working anymore for iOS7.
