OK. I posted a reply but it disappeared. Having seen Frank's post:
If a parameter is specified as an array then you can either pass a single dimensioned array or a list of items of a valid type. e.g

void Something (params int[] numbers){}

can be called so:

int[] x = {1, 2, 3};
Something (x);
//or
Something(1,2,3);
