New to the site, and C#, and the site has been a great help. I have been experimenting with the 'An Elegant C# Data Access Layer using the Template Pattern and Generics' article, hopefully someone can help me with this problem.
I have 3 objects: ObjectA, ObjectB, ObjectC. All 3 are derived from an object ParentObject. Parent Object has a property 'ID'.
If the objects are stored in a Collection like: Collection<ObjectA>, Collection<ObjectB>, Collection<ObjectC>.
Is there any way that I can use Collection<ParentObject> as a parameter to a single function in order to read the 'Id' Property from either of the Collections.
