Serialize enum to string

Question

I have an enum:

public enum Action {     Remove=1,     Add=2 } 

And a class:

[DataContract] public class Container {     [DataMember]     public Action Action {get; set;} } 

When serialize instance of Container to json I get: {Action:1} (in case Action is Remove).

I would like to get: {Action:Remove} (instead of int I need to ToString form of the enum)

Can I do it without adding another member to the class?

Using Json.Net, you can define a custom StringEnumConverter as

public class MyStringEnumConverter : Newtonsoft.Json.Converters.StringEnumConverter {     public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)     {         if (value is Action)         {             writer.WriteValue(Enum.GetName(typeof(Action),(Action)value));// or something else             return;         }          base.WriteJson(writer, value, serializer);     } } 

and serialize as

string json=JsonConvert.SerializeObject(container,new MyStringEnumConverter());
