create variables in method update()

I need advice on how I can create a variable in the update ()?
In Javascripts I would do the following:

function Update ()
{
var abc : int;
}

How to do it in C Sharp?
I tried it:
void Update()
{
public int abc;
}
but it does not work: (

 

Public makes no sense in methods, so just use:

Code (csharp):

1. int abc;

public defines the "visibility" of variables/methods, ... . As the variable only exists within the Update method, it can not be accesses from outside and thus you can't define its visibility.

 

If you declare it inside a method it only lives in that method. So no need for public or private.

Code (csharp):

1.  
2. void Update()
3. {
4.    int a;
5. }
6.  

 

Tkank you.
