Should I use string constants or string literals

Question

By default I use string constants in my code when I have a string of text that will be output to the screen via a messagebox, label, etc. My main reason for doing so is that I do not want these strings to change at runtime and this way nobody really touches them.

My question is:

It seems that from a memory point of view, this approach is creating an object whose lifetime will be decided by the GB whereas a string literal seems more efficient and will be disposed of more quickly. I know this is a rookie question but is there a benefit (no matter how tiny) when using a literal over a constant or should a constant be used in such scenarios.

I know it will not make any noticeable difference in my apps but I am trying to improve myself as a dev and build standards that I keep a reasonable amount of the time. :o)

Answer 1

Neither. The recommended way AFAIK is to use a resources file.

Answer 2

Prefer string constants to string literals, but the reason is to make your code more maintainable, not to improve its performance.
