Yes you're missing the params keyword which allows for a variable argument list. Look it up. Params gives you an array of object and you can pass any number of parameters as simple parameters.

public Test(params object[] args) { }

>I'd have to code a constructor for 0, 1, 2, and 3 arguments passed if I wanted any of them to be optional. I couldn't pass 2 and have the constructor run with only 2 passed and create a default value for the 3rd argument not passed (like vfp does) - it won't even compile. That's what I meant. You have to code for every possibility. You have to overload the constructor:
