Question

What is the best way to copy a BindingList?

Just use ForEach()? Or are there better ways?

Answer 1

Foreach pretty much is the easiest way, and the performance overhead is minimal if any.

Answer 2

Serialize the object then de-serialize to get a deep cloned non referenced copy

Answer 3

Just pass the old binding list as a parameter for the new binding list, on the constructor.

Answer 4

BindingList has a constructor which can take an IList. And BindingList implements IList. So you can just do the following:

BindingList newBL = new BindingList(oldBL);

Of course that creates a second list that just points at the same objects. If you actually want to clone the objects in the list then you have to do more work.
