OO Relationship modelling in .NET

Hi,

Dipping my toe into OO stuff here.

SoI've designed a simple application in UML. It has classes (obviously)in various one-to-one/one-to-many relationships and association classesto sort out the many-to-many relationships. Looks good on paper.

However,I'm getting myself into a dreadful tangle trying to actually representthis in code. It's the relationship modelling that's really getting meand I can't find any code samples. All I've got to go on so far is theadvice to "Use a reference variable as an attribute of a class" andthat "A reference variable points to an actual instance". But being apractical guy, I'd like to see a practical example and I can't findany.

Can anyone outline how this is supposed to work, orpoint me at a tutorial with actual code? VB in preference but I cantranslate C# if I have to.

Cheers,
