Why this method does not increment?

Felice Massaro

May be I had to much drinks last night. Why this method does not increment the value of "number" by 1 every time I receive the value "1" in "getTurns"?

class Turns

{

private int number;

public void Counts(int getTurn, out int getBack)

{

if (getTurn.Equals(1))

{

number++;

}

getBack = number;

}

Accepted answer
It sounds like you were calling the Count method from two different instances of the Turns class.

When number was an instance field, it would start off at 0 for each instance.

However, when you changed it to static, it would start off at 0 for the class as a whole and would be incremented by 1 as each instance called the Count method.

Yes. Thats it. Thanks for supporting.

Thanks for testing it, but doesn't work in my app. Actually I solved the problem changing the "private int number" to "static int number".
I do not understand why for you the original one is working. Thats interesting.

I've just tried it but it's working fine:

using System;

class Turns
{
private int number;

public void Counts(int getTurn, out int getBack)
{
if (getTurn.Equals(1))
{
number++;
}

getBack = number;

}
}

class test
{
static void Main()
{
Turns t = new Turns();
int i;
t.Counts(1, out i);
Console.WriteLine(i); // 1
t.Counts(1, out i);
Console.WriteLine(i); // 2
Console.ReadKey();
}
}
