Can you inherit enum C#?

Can we inherit enum in Java?
Inheritance Is Not Allowed for Enums. Now, let’s find out why we got our compiler error. When we compile an enum, the Java compiler does some magic to it: It turns the enum into a subclass of the abstract class java.
Can you extend an enum Swift?
We can extend the enum in two orthogonal directions: we can add new methods (or computed properties), or we can add new cases. Result and Optional are defined as enums; both the standard library and our own code can add extensions without having to worry about breaking things.
Can enum extend abstract class?
Java enum is a kind of a compiler magic. In byte code, any enum is represented as a class that extends the abstract class java. lang. Therefore, enum cannot extend any other class or enum : there is no multiple inheritance.
What can be used instead of enum?
Enum Alternatives in C#
- public enum Roles { Author, Editor, Administrator, SalesRepresentative }

Can we inherit enum in Swift?

Can a service be changed in a C # enum?

C# allows syntax to change the underlying representation of the enum values which looks like inheritance, but in actuality they still inherit from System.enum.
How to create a new enum in.net?
You can use .NET reflection to retrieve the labels and values from an existing enum at run-time ( Enum.GetNames () and Enum.GetValues () are the two specific methods you would use) and then use code injection to create a new one with those elements plus some new ones. This seems somewhat analagous to “inheriting from an existing enum”.
