DDD Refactoring: Enums++ with Enumeration Classes
DDD Refactoring: Enums++ with Enumeration Classes Let's refactor ENUMS by moving from traditional ENUM types to enumeration classes Understanding Problems with Enums Using C# Enum types has limitations: They are value types and cannot have behavior (methods). They cannot hold additional data. They are not easily extensible without modifying the original enum. They don’t support polymorphism. E xample Code public enum OrderStatus { Pending, Shipped, Delivered } I ssues with above code If you need to associate extra info (like display name or code), you need separate mappings. Adding logic (IsFinalStatus ) is impossible inside the Enum. F ix: Use Enumeration Classes Enumeration Classes Enumeration classes are implemented using sealed classes with static instances . They allow: Adding properties a. Adding methods b. Strong typing c. Extensibility Code Example public sealed class OrderStatus { public string Name { get ; } publi...
