Kuidas toimub andmete edastamine funktsiooni või meetodi sees?

In C#, data transfer to a function or method can be done in several ways:

• By value (by value) — the value of the argument is copied. Changes inside the method do not affect the original data.
• By reference (ref) — a reference to the variable is passed, changes inside the method reflect on the original.
• Output parameter (out) — used to return data from the method back to the calling code, the variable does not need to be initialized before the call.
• Parameters with the in keyword — passing by reference, but only for read inside the method.

Example:

void UpdateValue(ref int x) {
    x = 10; // will change the value of the variable passed by reference
}

int a = 5;
UpdateValue(ref a);
// now a == 10
