Static variable inside a function like in C ?

Questions & Answers
1

In C lang I could do something like this:

 void    f()
    {
        static int     a = 0;
    
        printf("%d

", a);
a++;
}
Calling this function 3 times would result in:
0
1

Is it possible to use static variables like this in C# ?

In other words, to make, somehow, a variable inside a function persistent, until the next call.

I know I could use global variables, but I would like to keep my code cleaner and less confusing.

There’s no such thing as a global variable in C#, and nor is there a modifier to make local variables retain values between invocations (there is a C# static modifier but that is for a totally different purpose).

But you can achieve what you describe with a member variable of the class:

public class ExampleClass
{
  private int a = 0;
  void f()
   { 
       Debug.Log(a);
       a++;
   }
}

There are no static function variables in C#.

As you’ve guessed already, you will have to use a class variable, static or not.

but I would like to keep my code cleaner and less confusing.

Functions/Methods shouldn’t hold persistent data in my opinion. But to each their own.
