Question

I have an enum that looks as follows:

public enum TransactionStatus { Open = 'O', Closed = 'C'}; 

and I’m pulling data from the database with a single character indicating – you guessed it – whether ‘O’ the transaction is open or ‘C’ the transaction is closed.

now because the data comes out of the database as an object I am having a heck of a time writing comparison code.

The best I can do is to write:

protected bool CharEnumEqualsCharObj(TransactionStatus enum_status, object obj_status) {     return ((char)enum_status).ToString() == obj_status.ToString(); } 

However, this is not the only character enum that I have to deal with, I have 5 or 6 and writting the same method for them is annoying to say the least. Supposedly all enums inherit from System.Enum but if I try to set that as the input type I get compilation errors. This is also in .NET 1.1 so generics are out of the question.

I’ve been struggling with this for a while. Does anyone have a better way of writing this method? Also, can anyone clarify the whole enums inherit from System.Enum but are not polymorphic thing?

Answer 1

static void Main(string[] args) {     object val = 'O';     Console.WriteLine(EnumEqual(TransactionStatus.Open, val));      val = 'R';     Console.WriteLine(EnumEqual(DirectionStatus.Left, val));      Console.ReadLine(); }  public static bool EnumEqual(Enum e, object boxedValue) {                             return e.Equals(Enum.ToObject(e.GetType(), (char)boxedValue)); }  public enum TransactionStatus { Open = 'O', Closed = 'C' }; public enum DirectionStatus { Left = 'L', Right = 'R' };
