Search in Listview using Separate Forms, and using System.IO

[CityThrille]

Hello! I'm a programming student and a newbie in forums. :)

How can I search for a data in listview from fist form using my second form?

For example, I entered 7 entries to my listview,
and when I press "Search in listview" button, the second form will open.
(My first form contains the listview table
and a button named "Search in listview", while the second form
contains a textbox which I'll type what I want to search,
for example the ID Number, and a button named "Search".)

To shorten my code, I like to use from the System.IO Namespace.
Is it possible to use System.IO? How?
It is frustrating that I can't even find it in Google.

:-/
Help is appreciated. Thank you.

That would depend on the language you're working in - VB.NET? C#?

If you'll tell us, we can move this post to the appropriate forum where the experts can help out. :)
