In memory, just like everything else.
I would recommend though, that you use a List<T> rather than an ArrayList - it is type safe, and you don't need to cast the elements every time you want to use them.

thank you but when I close my program in this case I lose my information?

OriginalGriff 28-Aug-11 7:48am

Yes.
Unless you specifically save it, everything will be lost when you program closes.
What to do want to save, and how?

I have no Precedure to save information.Iwant to enter information of some students and can save it's with access database or file or sql server.I need your help

I would use a database, myself - it's pretty simple, and the procedure is much the same whichever you chose.
There is a run-through here: http://www.codeproject.com/KB/database/sql_in_csharp.aspx
It's a bit old, but it is all still relevant and effective.
