Serialize .Net object to json, controlled using xml attributes

Question

I have a .Net object which I've been serializing to Xml and is decorated with Xml attributes. I would now like to serialize the same object to Json, preferably using the Newtonsoft Json.Net library.

I'd like to go directly from the .Net object in memory to a Json string (without serializing to Xml first). I do not wish to add any Json attributes to the class, but instead would like for the Json serializer to use the existing Xml attributes.

public class world{
  [XmlIgnore]
  public int ignoreMe{ get; }

  [XmlElement("foo")]
  public int bar{ get; }

  [XmlElement("marco")]
  public int polo{ get; }
}

becomes

{
  "foo":0,
  "marco":0
}

Answer 1

Use [JsonProperty(PropertyName="foo")] Attribute and set the PropertyName.
