QuestPond’s Interview Questions & Answers on learning data contract serializer and XML serializer

What is the difference between data contract serializer and XML serializer?

XML Serializer

  • It follows the Opt-out approach. It means all the public properties get serialized. If you don’t want something you have to specify explicitly.

  • It serializes only properties and again only public properties with both get and set accessor.

Data contract serializer

  • It follows Opt-In approach. It means we have to explicitly specify what we want to serialize.

  • It can serialize nonpublic members and fields also.
