Slightly modified from: http://www.wackylabs.net/2006/06/getting-the-xmlenumattribute-value-for-an-enum-field/

public static string ToString2 (this Enum e) {
    // Get the Type of the enum
    Type t = e.GetType ();

    // Get the FieldInfo for the member field with the enums name
    FieldInfo info = t.GetField (e.ToString ("G"));

    // Check to see if the XmlEnumAttribute is defined on this field
    if (!info.IsDefined (typeof (XmlEnumAttribute), false)) {
        // If no XmlEnumAttribute then return the string version of the enum.
        return e.ToString ("G");
    }

    // Get the XmlEnumAttribute
    object[] o = info.GetCustomAttributes (typeof (XmlEnumAttribute), false);
    XmlEnumAttribute att = (XmlEnumAttribute)o[0];
    return att.Name;
}
