Question

我有一个应该返回json的Web服务。我知道我可以使用JsonConvert.DeserializeObject<ClassType>(jsonString)。但是我无法从字符串创建类，因为我从结构结构未知的sql存储过程中获取了json字符串。它是动态的，每次Web服务调用时，我都会得到另一个结构。 Web服务代码为：

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
     [System.Web.Script.Services.ScriptService]
    public class Dispatcher_Service : System.Web.Services.WebService
    {

        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public string GetProcedureDetails(string JSON_IN)
        {
            try
            {
                string JSON_OUT = null;
                string ReturnValue = null;
                JObject json = new JObject();
                string ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
                using (SqlConnection SqlConn = new SqlConnection(ConnectionString))
                {
                    using (SqlCommand command = new SqlCommand("UWQ.p_Web_Dispatcher", SqlConn))
                    {
                        EventLog.WriteEntry("UWQ_DispatcherService", "INPUT: " + JSON_IN);
                        command.CommandType = CommandType.StoredProcedure;
                        //SqlDbType.NVarChar,-1 is nvarchar(max)
                        command.Parameters.Add("@_p_Request_JSON_IN", SqlDbType.NVarChar, -1).Value = JSON_IN;
                        command.Parameters.Add("@_p_Result_JSON_OUT", SqlDbType.NVarChar, -1);
                        command.Parameters["@_p_Result_JSON_OUT"].Direction = ParameterDirection.Output;
                        SqlConn.Open();
                        command.ExecuteNonQuery();
                        SqlConn.Close();
                        JSON_OUT = command.Parameters["@_p_Result_JSON_OUT"].Value.ToString();


                    }

                }
                return JSON_OUT;
            }
            catch (Exception ex)
            {
                EventLog.WriteEntry("UWQ_DispatcherService", "Error occur in  Get Procedure Details from Dispatcher: " + ex.Message);
                return null;
            }
        }

        void CreateEventLog()
        {
            try
            {
                if (!EventLog.SourceExists("UWQ_DispatcherService"))
                {
                    EventLog.CreateEventSource("UWQ_DispatcherService", "UWQ_DispatcherService");
                }
            }
            catch (Exception exc)
            {
                using (EventLog eventLog = new EventLog("Application"))
                {
                    eventLog.Source = "Application";
                    eventLog.WriteEntry("Can't Create source log massage:" + exc.Message, EventLogEntryType.Information, 101, 1);
                }
            }

        }
    }  

I have tried to use with Jobject.parse but it add extra braces to the json.

任何想法？

从Web服务返回JSON，而没有对象的构建类类型
