Determine if an element is part of a collection

[Lars]

Is there some efficient way to determine if a specific element is part of a Collection? By efficient I refer to a way in which I can avoid the process of looping through the collection comparing each and every element.

What I'm trying to achieve is to determine if a requirement exists in a diagram using VB-script.

Hello Lars,

you can use SQL (Repository.SQLQuery(slqString))

You find examples in Geerts Navigator (c#).
