无法使用wcf服务反序列化json数组

Question

我试图在项目中使用wcf服务对json数组中的数据进行DeSerialize。 数据被提取并且可以在调试中被注意到，但是我无法反序列化，或者我错误的其他内容。以下是我尝试反序列化的代码。 注意： - 我已经以正确的格式单独运行wcf应用程序及其返回的json数组与实际结果。

HotelServiceClient.cs

public class HotelServiceClient
    {
        private string BASE_URL = "http://localhost:50540/ServiceHotel.svc/";

        public List<HotelInfo> findall()
        {
            try
            {
                var webClient = new WebClient();
                var json = webClient.DownloadString(BASE_URL + "findall");
                var javaScriptJson = new JavaScriptSerializer();
                return javaScriptJson.Deserialize<List<HotelInfo>>(json);

            }
            catch
            {
                return null;
            }
        }

HotelInfo.cs

public class HotelInfo

            {
                return _hotelid;
            }

            set
            {
                _hotelid = value;
            }
        }

        [Display(Name = "Name")]
        public string Hotelname
        {
            get
            {
                return _hotelname;
            }

            set
            {

            }
        }

            get
            {
                return _hoteldesc;
            }

            set
            {
                _hoteldesc = value;
            }
        }

        [Display(Name = "price")]
        public string Hotelprice
        {
            get
            {
                return _hotelprice;
            }

            set
            {
                _hotelprice = value;
            }
        }

        [Display(Name = "picture")]
        public byte[] Hotelpicture
        {
            get
            {
                return _hotelpicture;
            }

            set
            {
                _hotelpicture = value;
            }
        }
