Esempio

Nell'esempio seguente viene creata un'istanza della classe DataContractSerializer che specifica il tipo da serializzare o deserializzare, l'elemento XML radice e lo spazio dei nomi (come parametri XmlDictionaryString) e un'istanza di un'interfaccia IEnumerable<T> che contiene i tipi utilizzati durante la deserializzazione. Il codice imposta anche i ignoreExtensionDataObject parametri e preserveObjectReferences su truee specifica un'implementazione dell'interfaccia per gestire i tipi legacy (tipi che non hanno l'attributo IDataContractSurrogateDataContractAttribute applicato). Per altre informazioni, vedere la documentazione di IDataContractSurrogate.
