Hello everyone,

This is a beginner question, but it's been frustrating me... I am using C#, by the way.

I'd like to make a few classes, each with their own properties and methods. I would also like to have a database to store certain instances of these classes in case I would ever need to look at them again. So, for example...

class Polygon
{
    String name;
    Double perimiter;
    int numSides;
    public Double GetArea()
    {
        // ...
    }
}

class Circle
{
    String name;
    Double radius;
    public void PrintName()
    {
        // ...
    }
}

Say I've got these classes. I also want a database that has the TABLES "Polygon" and "Circle" with the COLUMNS "name" "perimeter" "radius" etc. And I want an easy way to save a class instance into the database, or pull a class instance out of the database.

I have previously been using MS Access for my database stuff, which I don't mind using, but I would prefer if nothing other than .NET need to be installed.

I've been researching online a bit, but I wanted to get some opinions on here. I have looked at Linq-to-Sql, but it seems you need Sql-Server. Is this true? If so, I'd really rather not use it because I don't want to have to have it installed everywhere.

Anway, I'm just fishing for some ideas/insights/suggestions/etc. so please help me out if you can.

Thanks.
