Question

I am writing a JsonConverter for Json.NET which should allow me to convert any enum’s to a string value defined by a [Description] attribute.

For example:

public enum MyEnum {
    [Description("Sunday")] Sunday,
    [Description("Monday")] Monday,
    [Description("Tuesday")] Tuesday,
    [Description("Wednesday")] Wednesday,
    [Description("Thursday")] Thursday,
    [Description("Friday")] Friday,
    [Description("Saturday")] Saturday
}

I already have the code for supporting myEnum.Description() which will obviously return its string description.

In the JsonConverter implementation, there is this method:

    public override bool CanConvert(Type objectType)
    {

    }

I am trying to figure out how to determine if objectType is an Enum and return true so that the converter knows it can convert this object. Since I have many Enum‘s, I cannot explicitly check each one so I was hoping for a more generic way of accomplishing this.

Answer 1

Use the IsEnum property:

if(objectType.IsEnum) {
    return true;
}
