Question

Let’s say I have a custom class CustomClass, and I have a collection deriving from CollectionBase class named CustomClassCollection. Let’s say I do something like this:

CustomClassCollection a = new CustomClassCollection();
CustomClassCollection b = a;

When I change the CustomClass elements in a, the elements in b are also changed. How should I write these classes so that when I assign a to b and change the elements of b, a still stays the same?

Answer 1

You need a Clone (implementing IClonable) or a copy constructor for CustomClassCollection.
