tl;dr for local variables with literal values, const makes no difference at all. Your distinction of "inside methods" is very important. Let's look at it, then compare it with const fields.
12 mar 2024 · Constants are immutable values which are known at compile time and do not change for the life of the program. Constants are declared with the const modifier. Only the C# built-in types may be declared as const. Reference type constants other than String can only be initialized with a null value.
10 maj 2023 · Constants can be numbers, Boolean values, strings, or a null reference. Don’t create a constant to represent information that you expect to change at any time.
