Hello,
I have a class where I store a lot of setting names. Right now they're all
declared as consts :
public const CurDoc as string = "CURRENT_DOCUMENT"

>From what I know about const, every call to CurDoc will be replaced with the
text "CURRENT_DOCUMENT" during compilation. Is this right? If yes then
wouldn't it be better to declare it as:
public shared readonly CurDoc as string = "CURRENT_DOCUMENT"

This way there'll be a reference to this string, instead of it being copied
at each access point. What's the best practice for these?
Thanks
Amit
