Enum ToString()

I have a question. In full .NET, this code prints “Two”

class Program
{
    public enum Words
    {
        One,
        Two
    }

    static void Main(string[] args)
    {
        Words word = Words.Two;
        Console.WriteLine(word.ToString());
    }
}

In NETMF, this similar code prints “1”

public class Program
{
    public enum Words
    {
        One,
        Two
    }

    public static void Main()
    {
        Words word = Words.Two;
        Debug.Print(word.ToString());
    }
}

How do I make NETMF print “Two” instead of “1”?

The above are made up examples, in my real scenario, there are more enum values and I’d rather not do a giant switch case statement to translate the enum integer values back to human readable words. Thanks!

I ran into the same issue. Unfortunately, there currently doesn’t seem to be a way to get the string representation of an enum value. I think you’re stuck using a switch statement for now ???

Instead of switch a array lookup could be done:


   public enum Words
    {
      One,
      Two
    }

    string[] WordsStr = new string[2] {"One","Two"};

    public void Test()
    {
      Words word = Words.Two;
      Debug.Print(WordsStr[(int)word]);
    }

Instead of creating your array by hand, you can do:


public string[] GetStringArray(Type type)
{
    //use Reflection to get the fields in our enum
    FieldInfo[] info = type.GetFields();

    //new ArrayList to hold the values (will convert later)
    ArrayList fields = new ArrayList();

    //loop through all the fields
    foreach (FieldInfo fInfo in info)
    {
        //add each to our ArrayList
        fields.Add(fInfo.Name);
    }

    //now we convert to string array and return
    return (string[]) fields . ToArray ( typeof ( string ) );

  }

PS I don’t know why that link is appearing after ToArray, tried to add spaces but it’s still there :frowning:

Thats a neat function :slight_smile:

I’m assume Enum.Parse() doesn’t exist in .NET MF?

hari,

if you do this in .NETMF you will get what you are asking for.

public enum Words
{
      One = 1,
      Two
}

NETMF is targeted for small devices. So the enums’ names are not there.
If you need them, you have to create your own string array with the names.

@ hari - You can do something like this:


public enum WebSocketState
{
	Initialized = 0, // initial state
	Connecting,
	Connected,
	Disconnecting,
	Disconnected
}

public static class WebSocketStateExtensions
{
	public static string Name(this WebSocketState webSocketState)
	{
		string text = "";
		switch (webSocketState)
		{
			case WebSocketState.Initialized:
				text = "Initialized";
				break;
			case WebSocketState.Connecting:
				text = "Connecting";
				break;
			case WebSocketState.Connected:
				text = "Connected";
				break;
			case WebSocketState.Disconnecting:
				text = "Disconnecting";
				break;
			case WebSocketState.Disconnected:
				text = "Disconnected";
				break;
		}
		return text;
	}
}

Then use it like this:


WebSocketState wss = WebSocketState.Connecting;
string currentState = "Current state: " + wss.Name();
