Another thing that may affect what you want is the type accepted by the
function you say you want to pass it to (would you be able to give us the
signature of the function?). If you plan to write this function yourself,
then it probably won't make much of a difference.

Hi PvdG42
Thanks for the reply,

The language is vb.net 2005. The data types are strings , Name, Company ,
Service and it would be simpler if they were stroed in that order, and
will
be acc accessed sequentially from the beginning of the collection. As far
as
the file goes, there will be a mimimum of 1 record in the file, with an
esitmated maximum of about 200. I hope this helps in being able to give
advice and examples of the best way to handle this

regards

Dispite reading various web pages, i am still confused and stuck.
I am looping in a flat file and extracting 3 peices of information per
line
Name, Company , Service
the file will contain at least 1 line but an unlimited maximum lines.
What
i need to do is load the information into an array / ArrayList to be
able
to
parm it to a function

I have looked at arraylist and structures, but to be honest im still
just
as
baffled. Can any one provide an example and explination?

What language are you using? You ask for examples, and it would make
sense
if any examples provided were in the language you are using.

The ArrayList class defines a collection that can expand to hold any data
you want to store in it, so (compared to an Array, as you only mentioned
those two collections) that makes it a better choice for your needs as
you've described so far.

Yes, a struct may well be a good choice for your three fields. When you
define a struct, you are defining a new type to your language compiler,
so
you can then create an ArrayList that holds multiple instances of your
new
type.

What datatype are each of the three fields you want to store? How will
the
sets of fields you want to use as arguments be stored in your collection?
Any particular order? How will the field sets be accessed for method
calls?
Sequentially from the beginning of the collection?

All these questions need to be answered if you hope to get any good
examples.

Unlimited records on the input file? You must have some idea of the
potential high limit. If the number of records is really potentially
huge,
that too will influence what makes sense as a solution design.
