public void Request_CBS11Async(string ZCIZID)
        {
            using (var client = new HttpClient())
            {
                var url = "http://localhost:1000/Home/Get_CBS11";

                RequestDetail reqDetail = new RequestDetail();
                reqDetail.LASTCIF = "a";
                reqDetail.CURPAGE = "b";
                reqDetail.RCPAGE = "c";

                reqDetail.ZCONDITION = "e";
                reqDetail.ZSEARCH = "f";

                var json = Newtonsoft.Json.JsonConvert.SerializeObject(reqDetail);
                var content = new StringContent(json, System.Text.Encoding.UTF8, "application/json");
                var result = client.PostAsync(url, content);
            }
        }
