02-Sep-2014Constants perform the same tasks as read-only variables with some differences. The differences between constants and read-only are
Constants:
Constants are dealt with at compile-time.
Constants supports value-type variables.
Constants should be used when it is very unlikely that the value will ever change.
Read-only:
Read-only variables are evaluated at runtime.
Read-only variables can hold reference type variables.
Read-only variables should be used when run-time calculation is required.
