Implementing a UML association

[=?Utf-8?B?UGFvbG8=?=]

I have 3 classes - their associations are modelled in UML thus:

Class A: 1 --1..* Class B: 1 --1..* Class C

How would I implement this in C#?

Thanks

Let A contain a List<Band B contain a List<C>.

And make the code enforce minimum of 1 element,
if that is really important.

Re: Implementing a UML association

Arne: thank you for the reply. I am new to C# so sorry if this next question
is a bit basic. When I create an instance of Class A I would create a
List<class Bas part of the instantiation. As I create a number of instances
of class B in my application presumably I then have to Add them to the
List<class Bin the class A object?

I am new to C# so sorry if this next question
is a bit basic. When I create an instance of Class A I would create a
List<class Bas part of the instantiation. As I create a number of

instances

of class B in my application presumably I then have to Add them to the
List<class Bin the class A object?

The list should be private, so either the B's should be created and
added inside A or something outside A should create them and
call a method in A that does the add.
