how best to store these objects?

[mp]

I have a class cObject that has a property .Views, which is a collection
of 3 different view objects, cPlanView:cView, cElevationView:cView and
cIsometricView:cView.

So I think I want each cObject to have it's own .Views property

Which kind of collection would be best for such a small collection of
items? collection,dictionary,list?

List if it is lookup by index 0..COUNT-1
Dictionary if lookup by key

thank you Arne
here's what i'm trying, obviously it's very very wrong ;-) lol
the help says Dictionary has a property ".Item" to set and return entries
but I don't get that property when I try to use it.
any hints on where i'm going wrong appreciated

namespace BuildingComponentTest
{
class cViews:cBldgComponentGraphical
{
private Dictionary<string, cView> InternalDictionary;

//attempt to make property to return the "PlanView" object
public cPlanView PlanView
{
get { return InternalDictionary.Item("Planview"); }
//no item property appears in intellisense
set { InternalDictionary.Item("PlanView") = value ; }
}

//my first attempt at a constructor
//default constructor
public cViews ()
{
InternalDictionary = new Dictionary<string, cView>();

InternalDictionary.Add("PlanView", new cPlanView());
InternalDictionary.Add("ElevationView", new cElevationView());
InternalDictionary.Add("IsometricView", new cIsometricView());

get { return InternalDictionary.Item("Planview"); }

ok further reading found .Item property is, for whatever reason,
invisible so now using
private Dictionary<string, cView> InternalDictionary;

public cPlanView PlanView
{
get { return InternalDictionary["Planview"]; }
set { InternalDictionary["PlanView"] = value ; }
}
now the error is casting from cPlanView to cView, I thought cPlanView
was a "kind of" cView so thought this would work but obviously not

this seems to have gotten rid of compiler complaints
public cPlanView PlanView
{
get { return(cPlanView) InternalDictionary["Planview"]; }
set { InternalDictionary["PlanView"] = value ; }
}

You reference Dictionary Item using square brackets not round
round brackets around key.

[] not ().
