Hi everybody,

We have the following code to process Enums and convert them into a list of values to select from

T[] enumValues = (T[])Enum.GetValues(typeof(T));
            string[] enumNames = (string[])Enum.GetNames(typeof(T));

            for (int i = 0; i < enumValues.Length; i++)
            {
                bool selected = false;
                object enumUnderlyingValue = Convert.ChangeType(enumValues[i], enumUnderlyingType);

                if (omitEnumValue != null && enumUnderlyingValue.Equals(omitUnderlyingValue))
                {
                    // The Enum value matches the omitValue parameter, so we won't process it.
                    // This check is for enums that have a default value such as NotSpecified
                    // which we may not always want to include in a dropdown.
                }
                else
                {
                    Int32 enumValue = Convert.ToInt32(enumUnderlyingValue);
                    string enumName = GetFormattedEnumName<T>(enumNames[i]);

                    if (selectedUnderlyingValue != null)
                    {
                        selected = enumUnderlyingValue.Equals(selectedUnderlyingValue) ? true : false;
                    }

                    items.Add(GetNewSelectViewModel(selected, enumName, enumValue));
                }
            }

There is, unfortunately, a bug here. This code assumes that each enum simply has values corresponding to their number in the list, which is not true. Say, I have the following enum

  public enum LookupTypes : byte
    {
        [Description("Select Lookup Method")]
        Typing = 1,
        HotKeySelect = 2,
        SingleKeyLookup = 3,
        MultiKeyLookup = 4
    }
}

and I noticed that my drop-down didn't have the value I specified as selected using this code

var lookupTypes = EnumUtilities.EnumToEnumViewModel<LookupTypes>(selectEnumValue: LookupTypes.Typing);

so I started to debug this code and thus how I found this bug.

The problem is - how to now resolve it to use the actual value of enum instead of its number?

Thanks in advance.
