Re: Why properties cannot be used as ref or out arguments

Ah. Yes. Didn't think of the actual mechanics of how it presented the
properties behind it all. Thank you.

Is a shame though - or is there any way I can get around it using
delegates? I have a function that I require to set one of two
properties, and return a 3rd?

Because properties are implemented underneath as functions.
get_PropName
set_PropName

A ref argument cannot point to a func, and if it did, it would point
to the wrong function in any case.

ref arg needs the passing value; it would need the get_PropName function
for it.
but ref arg needs to set the value as well; it would need the
set_PropName function for it.
