RestSharp - 嵌套JSON数据的问题

Question

我已经和那些遇到同样问题的人尝试过其他答案，但我无法让它发挥作用。另外，我是新手。任何帮助表示赞赏。

当我运行此操作时，我的手机数据为空。

这是我从我的服务中获得的JSON数据。 {＆＃34; GetDirectoriesResult＆＃34;：＆＃34; [{\＆＃34; ID为\＆＃34;：1，\＆＃34;部门\＆＃34;：\＆＃34;承认\＆ ＃34; \＆＃34;部来看\＆＃34;：\＆＃34; \＆＃34; \＆＃34;电话\＆＃34;：\＆＃34; 555-444-4013 \ ＆＃34;，\＆＃34;评论\＆＃34;：\＆＃34;按1 \＆＃34;}，{\＆＃34; id \＆＃34;：2，\＆＃34 ;部门\＆＃34;：\＆＃34;门诊手术中心\＆＃34;，＆＃34; subdepartment \＆＃34;：\＆＃34; \＆＃34;，\＆＃34;电话\＆＃34;：\＆＃34; 555-444-4013 \＆＃34; \＆＃34;评论\＆＃34;：\＆＃34; \＆＃34;}]＆＃34 ;}

我的代码

    public class PhoneList
    {
//      public string GetDirectoriesResult { get; set; } 
        public List<Phone> Phones { get; set; }     //- can't get this working
    }

    public class Phone
    {
        public int id { get; set; }
        public string department { get; set; }
        public string subdepartment { get; set; }
        public string phone { get; set; }
        public string comments { get; set; }
    }


        public IRestResponse<PhoneList> Execute<PhoneList>(RestRequest request) where PhoneList : new()
        {
            PhoneList ro = new PhoneList();

            var client = new RestClient();
            client.BaseUrl = BaseUrl;

//          var request = new RestRequest();
            request.RequestFormat = DataFormat.Json;
            request.AddHeader("Content-Type", "application/json");
            request.AddJsonBody(ro);

            IRestResponse<PhoneList> response = client.Execute<PhoneList>(request);
            if (response.ErrorException != null)
            {
                const string message = "Error retrieving response.  Check inner details for more info.";
                var Exception = new ApplicationException(message, response.ErrorException);
                throw Exception;
            }

            return response;
        }
