newbie memory question

Hi all,

I have a program for race timing which currently stores to a dataset.
for a variety of reasons, I want to change this to an array.

If I have 500 participants, I will need to store 500 times format
"hh:mm:ss.00" and the order in which they cross the timing points.

so the array will look like

("00:00:04.65", "00:00:10.05", "00:00:18.09", "00:00:22.66", "18")

my question is does the line

Dim resultsArray(500,5) as string

presume that strings could be extremely long and therefore set aside a very
large section of memory?

Is there a more memory efficient way to do this, given that we know the
format of the data beforehand?

thanks

Neil

If you need all the data in memory, then your solution is OK. Maybe it's
better to utilize 'TimeSpan' objects to store the time
spans/durations/timing points instead of using strings to do that. The
optimal solution depends on what you want to do with the data (querying,
adding and removing datasets very often/seldom, ...).
