hi yuriy

you can use a foreach statement or a for loop for that matter with collections ie types that implement IEnumerable interface
so you can have an array(as vulpes has mentioned) or a List etc which contains the objects of your class and iterate over it using foreach statement

foreach only works with enumerable collections such as arrays, lists or even strings (collections of chars).

Also, the foreach iteration variable ('i' in your example) is read-only; in other words you can't assign anything to it.

I'm not really sure what you're trying to do but something like this should work:

public class myClass : Object
{
myObjectType[] objects;

public void Save()
{
objects = new myObjectType[3];

for(int i = 0; i < 3; i++)
{
objects[i] = ....; // whatever
}
}
}

Notice also that it's unnecessary to specify that a class inherits from Object - all classes do so by default if they don't inherit from any other class.
