Enum Types

Enum types are just like you'd expect. It let's API consumers know that a field can be only 1 of a set of values.

With our Person example we could add a Gender enum.

[JsonConverter(typeof(StringEnumConverter))]
public enum Gender {
    Female,
    Male,
    NotSpecified
}

// building our schema
schema.AddEnum<Gender>("Gender", "A persons Gender");

The GraphQL schema produced from this helps document and describe the data model to API users. Example GraphQL schema below

enum Gender {
  Female
  Male
  NotSpecified
}

type Person {
  firstName: String
  lastName: String
  gender: Gender
}
