How to get all descriptions of enum values with reflection?

Question

So I need to get a List from my enum

Here is what I have done so far:

enum definition

Answer 1

I created these extension methods

public static class EnumExtender
{
    public static string GetDescription(this Enum enumValue)
    {
        string output = null;
        Type type = enumValue.GetType();
        FieldInfo fi = type.GetField(enumValue.ToString());
        var attrs = fi.GetCustomAttributes(typeof(DescriptionAttribute), false) as DescriptionAttribute[];
        if (attrs.Length > 0) output = attrs[0].Description;
        return output;
    }

    public static IDictionary GetEnumValuesWithDescription(this Type type) where T : struct, IConvertible
    {
        if (!type.IsEnum)
        {
            throw new ArgumentException("T must be an enumerated type");
        }

        return type.GetEnumValues()
                .OfType()
                .ToDictionary(
                    key => key,
                    val => (val as Enum).GetDescription()
                );
    }
}

Usage

var stuff = typeof(TestEnum).GetEnumValuesWithDescription();

Will return a Dictionary with value as keys and descriptions as values. If you want just a list, you can change .ToDictionary to

.Select(o => (o as Enum).GetDescription())
.ToList()
