Question

I want to use C# to build a custom-made scripting language. It will have simple statements which are in fact method calls with arguments like:

Set("C1", 63);
Wait(1.5);
Incr("C1", 1);

Now, I want to provide also a loop and the usual C# syntax with the indexer is too complicated for such a simple thing. For example I would have this to loop 20 times:

for (20)
{
  Wait(1.5);
  Incr("C1", 1);      
}

Is there some way to achieve such a simple loop at least closely? (e.g. a wrapped method call inside the for statement or the like)

Thanks, Marcel

Answer 1

create a function extending ints:

public static class Extensions {

    public static void Times(this int n, Action action) {
        if (action != null)
            for (int i = 0; i < n; ++i)
                action();
    }

}

call it like:

20.Times(() => {
    Wait(1.5);
    Incr("C1", 1);
});
