ObservableDictionary类 <TKey, TValue> ：IDictionary <TKey, TValue> 作为DataContract

Question

How to decorate

public class ObservableDictionary<TKey, TValue> : IDictionary<TKey, TValue>, INotifyCollectionChanged, INotifyPropertyChanged

as DataContract (or something like this) in WCF service?

Answer 1

据我所记得，如果您的ObservableDictionary<TKey, TValue>类是可序列化的，则自WCF 3.5 SP1起，无需将其标记为DataContract （请参阅问题： WCF datacontract vs class serialize ）。

Answer 2

You need CollectionDataContractAttribute

The CollectionDataContractAttribute is also intended to be used with dictionary types to handle keyed collections. Dictionary types are classes that implement either the IDictionary or the IDictionary interface, for example, the Dictionary.
