Custom .NET Serialization doesn't seem to work

Question

I am using BinaryFormatter to serialize a collection of objects of class A stored in a System::Collections::Generic::List^.

Answer 1

From your description it sounds like the items within your list are possibly non-serializable; if you have control over that class can you verify if it is also tagged as serializable?

Also, have you tried using an XmlFormatter to be able to visually check the serialized data to see just how it's being built? It might provide some insight into whether the problem is occuring during serialization or deserialization.
