'Newtonsoft.Json.Linq.JArray' does not contain a definition for 'id'

hello sir, I want to know why I can not retrieve data even if there are data inside it .

first error:

'Newtonsoft.Json.Linq.JArray' does not contain a definition for 'id'

"BedTypes":{"size":"2","BedType":[{"id":"14","description":"1 king bed"},{"id":"25","description":"2 twin beds"}]}

this is part of json where data is available.

  foreach (var a in root.HotelRoomAvailabilityResponse.HotelRoomResponse)
                    {
                        try
                        {

                           string bedtypeid = a.BedTypes.BedType.id;

 public class BedType
{
    public string id { get; set; }
    public string description { get; set; }
}

public class BedTypes
{
    public string size { get; set; }
    public BedType BedType { get; set; }
}
