How can I make an “abstract” enum in a .NET class library?

Question

I\'m making a server library in which the packet association is done by enum.

public enum ServerOperationCode : byte
{
    LoginResponse = 0x00,
    Selectio         


        

Answer 1

1. Create an Enum for LoginResponse, SelectionResponse, etc., but don't specify the values.

2. Have ServerOperationCode and ClientOperationCode implement a function that, given an integer bytecode, returns the appropriate value from your Enum.

Example:

public enum OperationCode
{
 LoginResponse,
 SelectionResponse,
 BlahBlahResponse
}

public interface IOperationCodeTranslator {
 public OperationCode GetOperationCode(byte inputcode);
 }

public class ServerOperationCode : IOperationCodeTranslator
{
  public OperationCode GetOperationCode(byte inputcode) {
    switch(inputcode) {
       case 0x00: return OperationCode.LoginResponse;
      [...]
    } 
}

Caveat: since interfaces can't define static functions, ServerOperationCode and ClientOperationCode would only be able to implement a common interface if said function is an instance function. If they don't need to implement a common interface, GetOperationCode can be a static function.

(Apologies for any C# snafus, it's not my first language...)
