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

I don't think an interface would work, as this is generic - for example,
on one data entry screen, I might have 10 textboxes with strings, 3 with
dates etc and I would want to call these generic functions 10 time for
the string properties, and 3 times for the date properties - so there's
no way my class could implement a single interface for it. And there
will be a few places where I want to call the same generic functions, so
1 interface with multiple properties won't work either.

Is it sufficiently general that you could create an interface with the
properties in, and then pass an implementation of that interface into
the method?

You certainly *could* do it with delegates, but it would feel a little
ugly.
