How to get field name in type safe enum

Question

I have implemented the Type safe enum pattern in our solution, and now I want to get the name of the fields in string format. How do I achieve that? This is my type safe enum class:

    public sealed class Statuses
    {
      private readonly String _name;
      private static readonly Dictionary<string, Statuses> Instance 
= new Dictionary<string, Statuses>();

      private Statuses(string name)
      {
          _name = name;

          Instance[name] = this;
      }

      public static explicit operator Statuses(string str)
      {
          Statuses result;
          if (Instance.TryGetValue(str, out result))
              return result;
          else
              throw new InvalidCastException();
      }


     public static readonly Statuses Submitted = new Statuses("Submitted by user");
     public static readonly Statuses Selected = new Statuses("Selected by user");

     public static IEnumerable<Statuses> AllStatuses
    {
        get
        {
            return Instance.Values;

        }
    }
    public override String ToString()
    {
        return _name;
    }

And I would like to add a property to return the name of the current field like this:

 public string StateCode
        {
            get
            {
                return //The current fields name
            }
        }

Usage:

[TestMethod]
public void TestGetStatusName()
{
var state = Statuses.Selected;
Assert.AreEqual("Selected", state.StateCode);            
}

Answer 1

There might be some more effective way, but this is the solution i found:

public string StateCode
{
    get
    {
        return GetType()
            .GetFields(BindingFlags.Public | BindingFlags.Static)
            .First(f => f.FieldType == typeof (Statuses) && ToString() == f.GetValue(null).ToString())
            .Name;
    }
}

I would follow the way that the link you gave did, pass in the field name as a second string.

private Statuses(string name, string description)

public static readonly Statuses Submitted = new Statuses("Submitted", "Submitted by user");

The only problem then becomes ensuring you are consistently using either the description or the name (in your question you are using the description).
