Enum to dictionary

Question

I want to implement an extension method which converts an enum to a dictionary:

public static Dictionary ToDictionary(this Enum @enum)
{
           


        

Answer 1

Here is the extension method I use to convert enumerations. The only difference is that I am returning IEnumerbale> for my purpose:

public static IEnumerable> ToListOfKeyValuePairs(this TEnum enumeration) where TEnum : struct
{
    return from TEnum e in Enum.GetValues(typeof(TEnum))
            select new KeyValuePair
                (
                    (int)Enum.Parse(typeof(TEnum), e.ToString()),
                    Regex.Replace(e.ToString(), "[A-Z]", x => string.Concat(" ", x.Value[0])).Trim()
                );
}

It also adds spaces for the value.

Example:

enum Province
{
    BritishColumbia = 0,
    Ontario = 1
}

Usage:

<% foreach(var item in Province.BritishColumbia.ToListOfKeyValuePairs()){ %>
    <%=item.Value %>
<% } %>

Output:

    British Columbia
    Ontario

Though @Paul Ruane is correct I have found this to be a very useful extension method. It's not a perfect world.
