[EASY] C# Function/void that will access an object given in the arguments.

[TommyTwommy]

lets say I have an integer declared like this:

 

int something = 0;

 

and I have a function that takes 1 argument like this:

private void Something(int someInt)
{
       someInt++;
}

private void Button1_Clicl()
{
       Something(something);
}

 

How can I make my function directly access the object I gave it in the argument? I don't want my function to +1 someInt from the argument, but the actual int something.

 

Why I need this? Cuz it would make my could shorter multiple times, because currently I'm checking each object through many if loops and if I could do it with a function with the given parameter it would be much easier.

You would like to have a pointer, but since it is C# then there is no pointers and you would need to wrap your int into object and pass that object to te function,t hen function can access such obiect's member and modify it, so it won't be only modified inside function but it will remain modified as object aren't passed by value but by reference.

Wow, that is very nice of C#. Thanks!

Another thing I can think of is just return value and assign it back to the variable you want to modify. So oy pass value to function, moify it and return it back and assign it back to the variable.

I thought you can use references...

It would be harder doing it through a function unfortunately...

I don't know how complex is your case but according to your example it would look like this:

 

private void Something(int someInt)
{
       someInt++;
       return someInt;
}

private void Button1_Clicl()
{
       something = Something(something);
}

private void Button1_Clicl()
{
       something = Something(something);
}

 

Yes it is much more complex, I'm using multiple parameters. I would have bunch of return's if I used a function since I have a lot of if statements.
