How can I use Generics to create a way of making an IEnumerable from an enum?

Question

Given an enum like this:

public enum City {
    London    = 1,
    Liverpool  = 20,
    Leeds       = 25
}

public enum House {
    OneFloor    = 1,
    TwoF         


        

Answer 1

This function might help you:

public static IEnumerable> GetValues() where T : struct
{
        var t = typeof(T);
        if(!t.IsEnum)
            throw new ArgumentException("Not an enum type");

        return Enum.GetValues(t).Cast().Select (x => 
               new KeyValuePair(
                   (int)Enum.ToObject(t, x), 
                    x.ToString()));
}

Usage:

var values = GetValues();
