Question

I am using the following:

    public static SelectList GetOptions<T>(string value = null) where T : struct
    {
        var values = EnumUtilities.GetSpacedOptions<T>();
        var options = new SelectList(values, "Value", "Text", value);
        return options;
    }

    public static IEnumerable<SelectListItem> GetSpacedOptions<T>(bool zeroPad = false) where T : struct
    {
        var t = typeof(T);
        if (!t.IsEnum)
        {
            throw new ArgumentException("Not an enum type");
        }
        var numberFormat = zeroPad ? "D2" : "g";
        var options = Enum.GetValues(t).Cast<T>()
            .Select(x => new SelectListItem
            {
                Value = ((int) Enum.ToObject(t, x)).ToString(numberFormat),
                Text = Regex.Replace(x.ToString(), "([A-Z])", " $1").Trim()
            });
        return options;

My enum has values:

public enum DefaultStatus {
    Release = 0,
    Review = 1,
    InProgress = 2,
    Concept = 3,
    None = 99
};

From what I understand the number format should give my values of “01”,”02″ etc but it’s giving me “”1″,”2″,”3” ..

Is there something obvious I’m doing wrong?

Answer 1

Your GetSpacedOptions has optional parameter zeroPad with default value false.

Use

var values = EnumUtilities.GetSpacedOptions<T>(true);

instead of

var values = EnumUtilities.GetSpacedOptions<T>();
