How to tell Json.Net to globally apply StringEnumConverter to all enums

Question

I want to deserialize enums into their string representation and vice versa using json.net. The only way I can define a structure to apply its StringEnumConverter is to annotate the given properties as follows:

 [JsonConverter(typeof(StringEnumConverter))] public virtual MyEnums MyEnum { get; set; } 

However, in my case it would be much more convenient to configure json.net all over the world so that all enumerations get (de) serialized using StringEnumConverter without the need for additional annotations.

Is there any way to do this, for example. using custom JsonSerializerSettings ?

Answer 1

Add a StringEnumConverter to the JsonSerializerSettings converter JsonSerializerSettings .

Documentation: Serialization with JsonConverters

If you want the serializer to use camelCasing, you can also set this:

 SerializerSettings.Converters.Add( new StringEnumConverter { CamelCaseText = true }); 

This will serialize SomeValue to SomeValue .

Other answers work for ASP.NET, but if you want to set these parameters, usually to call JsonConvert in any context, you can do:

 JsonConvert.DefaultSettings = (() => { var settings = new JsonSerializerSettings(); settings.Converters.Add(new StringEnumConverter {CamelCaseText = true}); return settings; });

In your application Global.asax.cs

 HttpConfiguration config = GlobalConfiguration.Configuration; config.Formatters.JsonFormatter.SerializerSettings.Converters.Add (new Newtonsoft.Json.Converters.StringEnumConverter());
