Question

I want to set some attributes just before the object is serialized, but as it can be serialized from several locations, is there a way to do this using the OnSerializing method (or similar) for Xml serialization – my class is largely like this – but the On… methods are not being called…:

[Serializable] [XmlRoot(ElementName = 'ResponseDetails', IsNullable = false)] public class ResponseDetails {     public ResponseDetails() {}       [OnSerializing]     internal void OnSerializingMethod(StreamingContext context)     {         logger.Info('Serializing response');     }      [OnSerialized]     internal void OnSerializedMethod(StreamingContext context)     {         logger.Info('Serialized response');     }      [OnDeserialized]     internal void OnDeserializedMethod(StreamingContext context)     {         logger.Info('Deserialized response');     }      [OnDeserializing]     internal void OnDeserializingMethod(StreamingContext context)     {         logger.Info('Deserializing response');     }

No, XmlSerializer does not support this. If you’re using .NET 3.0 or later, take a look at the DataContractSerializer.
