Better Way to Save in Database?

Hi

I want to save properties of object array in db.So i use foreach loop.But i think it's not better way coz connection will be opened and closed again and again.

May i know the way to avoid it.

Now code is :

foreach (AA a in List)
{

//to save in db..
SaveToDb(a.pro1,a.pro2);
}
