functions in C#

Question

As in c # to create and then call the function? In C + + do so:

int func (int value) 
{ 
   value +=2;
}

But as is done in c #?

Answer 1

Here's the same function translated in C#:

public void Func(ref int value) 
{
   // Parameter is passed by reference so any modification
   // to the value will propagate to the caller
   value +=2;
}

And call it like this:

int value = 5;
Func(ref value); // value is now 7

---

UPDATE:

If as an alternative you don't want to reflect the modifications made to the value parameter outside the function you could declare it like this:

public void Func(int value) 
{ 
   // Parameter is passed by value so any modification
   // to the value will not propagate to the caller
   value +=2;
}

And call like this:

int value = 5;
Func(value); // value is still 5

Answer 2

Considering your example is wrong... well, anyway.

public void func(ref int value)
{
  value+=2;
}
