BinaryFormatter and Deserialization Complex objects

Question

Can not deserialize following object graph. That Exception occurs when deserialize method called on BinaryFormmater: System.Runtime.Serialization.SerializationException :

Answer 1

Your serialization will succeed when you implement class C as following:

[Serializable]
public class C : IDictionary
{
    private Dictionary _inner = new Dictionary;

    // implement interface ...
}

The problem is the serialization of the Dictionary derived class.
