Strongly typed boxed values and reference to them...

  • Article

I just found this on my hard-disk. I thought I would share:

int ^ stronglyTypedBoxedValue = 1234 ; // C++/CLI feature

int copyOfUnboxedValue = *stronglyTypedBoxedValue ;

int % referenceIntoBox = *stronglyTypedBoxedValue ; // C++/CLI feature

referenceIntoBox = 4321 ; // Sets the value INSIDE the box!

Debug::Assert( copyOfUnboxedValue == 1234 ) ;

Debug::Assert( *stronglyTypedBoxedValue == 4321 ) ;

Debug::Assert( *stronglyTypedBoxedValue == referenceIntoBox ) ;

Check Boxing under C++: The Most Powerful Language for .NET Framework Programming if you're interested in those lines of code.
