DataContractJsonSerializer and Enums

Question

When I serialize a enum value using DataContractJsonSerializer, it serializes the numerical value of the enum, not the string name.

IE:

enum foo
{

To get 2 way serialization/deserilization for wcf json you can add a second get set property of type string, when you're construction your json object in javascript use the string named property, on the server side use the strongly typed enum version: e.g.

public class DTOSearchCriteria {
  public int ? ManufacturerID { get; set; }
  public int ? ModelID { get; set; }

  private SortBy _sort;

  public SortBy SortType {
    get { return _sort; }
    set { _sort = value; }
  }

  public String Sort {
    get {
      return _sort.ToString();
    }
    set {
      _sort = (SortBy) Enum.Parse(typeof(SortBy), value);
    }
  }

  public int PageSize { get; set; }
  public int PageNumber { get; set; }
}

public enum SortBy {
  PriceDescending,
  PriceAscending
}
