Serializing Dictionaries

I think there might be some updates here for .NET 3.5. I am having no problem with a serialized Dictionary<int, List<int>> that I am using in WCF. I think the difference might be a different serializer. When using a DataContract, the NetDataContractSerializer is being used by default. Let's put it this way. I got the values on the server, passed them back through WCF and I got what I started with no problem. The class is not marked Serializable, it is marked DataContract and compiliation does not complain either.

So this is probably not an issue with WCF if you don't need to mark a class Serializable as well. This may work with a BinaryFormatter for serialization as well.

Ignore previous comment, anything derived from IDictionary apparently cannot be (de)serialized.

Another idea for refactoring though: the serializable key value pair struct could be implemented without generic parameters because the encapsulating class already specifies them, thus the struct could simply be non-generic like this:

public struct SerializableKeyValuePair

{

public K Key;

public V Value;

public SerializableKeyValuePair(KeyValuePair<K, V> kvp)

{

this.Key = kvp.Key;

this.Value = kvp.Value;

}

Why are you trying to (de)serialize IDictionary<K,V> when .NET has a perfectly serializable class Dictionary<K,V>??
