converting from string to array

[darrel]

well, I've never used arrays and quickly finding that I'm a bit over my
head. I've hit a catch-22 in my understanding of arrays.

I have a comma delimted string that may be of any length:

2, 4, 34

To convert something to an array, it looks like I use the SPLIT command to
populate the array within for/while loop.

But the catch is that to dim an array, it looks like I need to tell it the
number of items I want to store in it to begin with.

So, I'm a bit confused, as SPLIT appears to also make an array. Can I not go
from a split function directly to an array or do I first need to count the
items to dim the array, and then populate it from the split?

Could you not use the array that is returned from Split?

Split() does all the work for you - e.g.

string strElements = "1,2,3,4,5,6,7,8";
Array astrElements = strElements.Split(',');
int intArrayLength = astrElements.Length; // returns 8
foreach(string strElement in astrElements)
{
// do something with each element of the array in turn
}

Ah, OK, so it's definitely not as complicated as I thought. That definitely
makes sense that split would dim the array for me with the applicable amount
of items.

Thanks!

That's what I'm confused about. When I dim an array, don't I need to tell it
how many items it contains? Or does the split function, by default, dim the
array for me?
