accessing member variables directly vs property accessor

[TS]

is it preferred to access member variables directly in code, on the page
that declared them, versus going thru a property accessor? I would think
that since theres no security concerns or anything it would be more
efficient to access directly. I also don't think that you would need to do
any special validation since the class developer knows what the rules are.

Note, i am not referring to accessing member variables declared in a
different class.

any comments appreciated

Thanks

Depends on what your doing... I would use a property accessor from within
it's class if that property does or will do something non-trivial, like for
instance late creation of an object or possibily validating paramter values
etc...

it would be more efficient to access directly

Thi isn't necessarily the case. When run in release mode outside of the IDE
the Jitter will inline code so the property execution speed "overhead" could
be factored out.

Hello TS,

Using properties instead of fields is more natural way. You don't need to
gave direct access to your fields, all fields shoul be private/protected.
Look at any .NET coding style (for exaple Microsoft one on the msdn)

Properties are more secure and elegant way, because u can easily control
access to your fields

Hi TS,

It's better to create properties to access the member variables. As your
design might be changed in the future, you'll have more flexibility on
controlling the access to those variables. Less code need to be modified to
change the access to the variables.
