Anyway to get JsonConvert.SerializeObject to ignore the JsonConverter attribute on a property?

Question

I have a class that I cannot change:

public enum MyEnum {
    Item1 = 0,
    Item2 = 1
}
public class foo {
    [JsonConverter(typeof(StringEnumConverter))]

I do not believe you can, as it is part of the definition. You'll have to remove the attribute and add the converter to the serializer settings instead:

var serializerSettings = new JsonSerializerSettings
{
    NullValueHandling = NullValueHandling.Ignore,
    DefaultValueHandling = DefaultValueHandling.IgnoreAndPopulate,

    Converters = new List { new StringEnumConverter() },

    ContractResolver = new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver()
};

In that case you can omit it if you don't want to use it. There is one thing I forgot to mention, the converter has to check the type in CanConvert:

public class StringEnumConverter: JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return typeof(MyEnum);
    }
}

I didn't test the code, but you'll get the idea.
