我认为您***在这里实现IXmlSerializable，因为您确实不希望滥发地序列化基类中的所有内容(而且我不相信您坦率地说可以.

I think you are better off implementing IXmlSerializable here, as you really don't want to indiscriminately serialize everything in the base class (and I don't believe you can, quite frankly).

相反，在MyCustomClass上实现IXmlSerializable，然后DataContractJsonSerializer将能够使用该实现向JSON序列化/从JSON序列化.

Rather, implement IXmlSerializable on MyCustomClass, and then the DataContractJsonSerializer will be able to use that implementation to serialize to/from JSON.
