Serialize enum to JSON using attribute value, not enum value

Question

I have an enum which contains attributes on each value, for example:

public enum MyEnum 
{
    [MyEnumAttribute("val01")]
    Value01,
    
    [MyEnumAttribute("val02")]
    Value02
}

This enum is used as a property in a class, for example:

public class MyDataObject 
{
    public string Name { get; set; }
    public MyEnum EnumOption { get; set; }
}

How can I serialize this object to JSON (preferably using Newtonsoft.Json), using the value from MyEnumAttribute instead of the enum value?

Edit:

Ideally, I'd also like to be able to deserialise the JSON into an instance of MyDataObject, mapping the values val01 to MyEnum.Value01, val02 to MyEnum.Value02 etc

or if you don't want custom converter - then easy & dirty way - add ignore to enum property + provide additional string property with get / set logic for (de)serialization based on custom attributes — Lanorkin, Jul 02 '19 at 15:19
Does it have to be a *custom* attribute? Json.NET's `StringEnumConverter` does support `EnumMemberAttribute` as shown in [How to serialize enums to different property name using json.net](https://stackoverflow.com/q/26391632) and [parsing an enumeration in JSON.net](https://stackoverflow.com/q/7799769). — dbc, Jul 02 '19 at 19:33
@dbc You're absolutely right, and that's all I need in the short term, thanks. At some point I'll need to include more properties in the attribute, in which case it sounds like I'll need a custom enum converter, which doesnt seem too bad. — devklick, Jul 02 '19 at 19:45
