    [DataMember]
    string name;
    [DataMember]
    int age;
    [Da         


        

Answer 1

Yes,you can do it with JSON.NET:

dynamic dycperson= JsonConvert.DeserializeObject(@"{
'name':'Chris',
'age':100,
'birthplace':'UK',
'height':170,
'birthdate':'08/08/1913'}");
Person person = new Person{
  name = dycperson.name,
  age=dycperson.age,
  height=dycperson.height,
  unused= new {birthplace = dycperson.birthplace, birthdate=dycperson.birthdate}
};

Answer 2

You should be able to use the [JsonExtensionData] attribute for this: http://james.newtonking.com/archive/2013/05/08/json-net-5-0-release-5-defaultsettings-and-extension-data

void Main()
{
    var str = "{\r\n    \"name\":\"Chris\",\r\n    \"age\":100,\r\n    \"birthplace\":\"UK\",\r\n    \"height\":170," +
    "\r\n    \"birthdate\":\"08/08/1913\",\r\n}";
    var person = JsonConvert.DeserializeObject<Person>(str);
    Console.WriteLine(person.name);
    Console.WriteLine(person.other["birthplace"]);
}

class Person
{
    public string name;
    public int age;
    public int height;
    [JsonExtensionData]
    public IDictionary<string, object> other;
}
