Serializing A Custom BindableDictionary<TKey,TValue> ?

Question

Question

How would I go about serializing this custom BindableDictionary given that it implements IDictionary and IBindingList?

BindableDictionary

What you need to do usually in these cases is serialise the data. to do this I simply the data into a List<KevValuePair<Tkey,Tvalue>> which serialises fine.
