c# - How to use Enums with Dynamic Linq?

Question

I would like to use enumerations in my dynamic LINQ queries.

Is it possible, and if, how?

Consider the code bellow:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Dynamic;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            Room aRoom = new Room() { Name = "a Room" };
            Room bRoom = new Room() { Name = "b Room" };
            Room cRoom = new Room() { Name = "c Room" };

            House myHouse = new House
            {
                Rooms = new List<Room>(new Room[] { aRoom }),
                MainRoom = aRoom
            };
            House yourHouse = new House()
            {
                Rooms = new List<Room>(new Room[] { bRoom, cRoom }),
                MainRoom = bRoom
            };
            House donaldsHouse = new House()
            {
                Rooms = new List<Room>(new Room[] { aRoom, bRoom, cRoom }),
                MainRoom = aRoom
            };

            var houses = new List<House>(new House[] { myHouse, yourHouse, donaldsHouse });

            // MainRoom.Name = "a Room" and Rooms.Count = 3 or 
            // ?????????????????????????
            var aRoomsHouses = houses.AsQueryable<House>().Where("MainRoom.Type = "RoomType.Kitchen"");

            Console.WriteLine("aRoomsHouses count = {0}", aRoomsHouses.Count());
            Console.ReadKey();
        }
    }

    public class House
    {
        public string Address { get; set; }
        public double Area { get; set; }
        public Room MainRoom { get; set; }
        public List<Room> Rooms { get; set; }
    }

    public class Room
    {
        public double Area { get; set; }
        public string Name { get; set; }
        public RoomType Type { get; set; }
    }

    public enum RoomType
    {
        Kitchen,
        Bedroom,
        Library,
        Office
    }
}

Answer 1

I encountered this same issue and tried the marked answer specified by @Steve Wilkes but it didn't work for me !! Then I discovered that dynamic LINQ has an HTML documentation in the same package which mentioned that Enums can be specified as String Literals.

houses.AsQueryable<House>().Where("MainRoom.Type = "Kitchen"")

Which worked for me.
