    Get the dictionary from enum.

    public static IDictionary ToDictionary(this Type enumType)
{
    return Enum.GetValues(enumType)
    .Cast()
    .ToDictionary(v => ((Enum)v).ToEnumDescription(), k => (int)k); 
}



    Now call this like...
    


    var dic = typeof(ActivityType).ToDictionary();

    


    EnumDecription Ext Method
    


    public static string ToEnumDescription(this Enum en) //ext method
{
    Type type = en.GetType();
    MemberInfo[] memInfo = type.GetMember(en.ToString());
    if (memInfo != null && memInfo.Length > 0)
    {
        object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
        if (attrs != null && attrs.Length > 0)
            return ((DescriptionAttribute)attrs[0]).Description;
    }
    return en.ToString();
}

public enum ActivityType
{
    [Description("Drip Plan Email")]
    DripPlanEmail = 1,
    [Description("Modification")]
    Modification = 2,
    [Description("View")]
    View = 3,
    [Description("E-Alert Sent")]
    EAlertSent = 4,
    [Description("E-Alert View")]
    EAlertView = 5
}
