Re: Array vs List<>

I wondered if someone would say something like that :)

In this situation I typically have two arrays

	classA [] a = whatever1();
	classB [] b = whatever2(); // same size as a

and I need to do this:

// no way to do this without indexed access
for (int i=0 ; i<a.Length ; i++)
{
	ProcessElements(a[i], b[i]);
}

The more complete object model solution would probably be to define something like

struct A_and_B
{
	A a;
	B b;
}

Allowing me to instead iterate through a single array of type A_and_B[] without worrying about indexes.

While that is a possible solution, I'm dubious about whether that leads to better or clearer code, since you've now got a whole additional type (and possibly quite an artificial, nonintuitive, one) that's there purely for use in a single method.
