c# parameters question

Question

I am new to c# and need help understanding what going on in the following function

    public bool parse(String s)
    {
        table.Clear();
        return parse(s, table, null);
    }

where table is a Dictionary. I can see that is is recursive but how is parse being passed three params when it is defined to take just a string?

EDIT: how do I delete a question? parse has been overloaded facepalm

Answer 1

it is overloaded parse exists that accepts 3 arguments.
