How to accept multiple names for a single property on newtonsoft JSON de-serialization?

Question

We have a standard json format that we defined (the typo is on purpose):

{
  "Name" : "John",
  "Salari" : "150000"
}

which is de-serialized (using newtonsoft) to:

class Person
{
    public string Name;
    public string Salari;
}

Is there a way to change Salari to Salary and still be able to accept messages with the old name? Something like:

class Person
{
    public string Name;
    [DeserializeAlso("Salari")]
    public string Salary;
}

To make newtonsoft de-serializer understand that Salari should be de-serialized to the Salary field?

Is string.Replace("\"Salari\",\"Salary\") is out of the question? — Nissim, Jun 16 '15 at 09:30

@Nissim I'd rather not since that would require keeping track of it in a lot of places — Shmoopy, Jun 16 '15 at 09:32
@AndreiV Wouldn't that cross 'Salary' off and just keep 'Salari' ? — Shmoopy, Jun 16 '15 at 09:33
@AndreiV I think shmoopy wants to use anonymous objects. the answer you referenced requires the object to exist — Nissim, Jun 16 '15 at 09:33
I think I understand now: you want `{"Name" : "John", "Salari" : "150000"}` and `{"Name" : "John", "Salary" : "150000"}` to be deserialized in the same way, i.e. in the same object type. — Andrei V, Jun 16 '15 at 09:35

I don't think that that's possible out of the box... You might need a custom deserializer. — Andrei V, Jun 16 '15 at 09:39
@BojanKomazec Thanks! it's getting impossible now days to ask a unique question in SO :) — Shmoopy, Jun 16 '15 at 09:39

You can make use of properties:

class Person
{
  protected string _Salary;
  public string Salary
  {
    get { return _Salary; }
    set { _Salary = value; }
  }
  public string Name { get; set; } 
}

class BackwardCompatiblePerson : Person
{
  public string Salari 
  {
    get { return _Salary; }
    set { _Salary = value; }
  }
}

And use Person for serialization & BackwardCompatiblePerson for deserialization.
