具有多个表的JSON字符串

我正在调用一个Web服务，该服务返回一个包含来自DataSet的多个表对象的JSON字符串。我试过无数的选项，并且无法访问我的成功函数中的JSON数组。在ajax调用中，data.d返回一个字符串，data.d.Table返回undefined。 JSON字符串验证。有人能告诉我我做错了什么吗？我对JSON相当陌生。具有多个表的JSON字符串

JSON字符串：

{"d":"{\"Table\":[{\"PID_Key\":1379391,\"EMP_NAME\":\"Alemao, Francisco | 3024250\"},{\"PID_Key\":1405973,\"EMP_NAME\":\"De Michieli, Francis | 3024570\"},{\"PID_Key\":1143321,\"EMP_NAME\":\"Ferris, Nick | 3024340\"},{\"PID_Key\":1557903,\"EMP_NAME\":\"Frison, Monika | 3024938\"},{\"PID_Key\":1220009,\"EMP_NAME\":\"Hand, Niccoli | 3024358\"},{\"PID_Key\":1592556,\"EMP_NAME\":\"Kearns, Ronald | 3024183\"},{\"PID_Key\":1552113,\"EMP_NAME\":\"Kurcz, Krystal | 3024911\"},{\"PID_Key\":1637525,\"EMP_NAME\":\"Leasure, Katherine | 3024100\"},{\"PID_Key\":1637274,\"EMP_NAME\":\"Myers, Lynn | 3024106\"},{\"PID_Key\":1418148,\"EMP_NAME\":\"Olson, Amy | 3024663\"},{\"PID_Key\":1368903,\"EMP_NAME\":\"Rosemond, Courtniegh | 3024110\"},{\"PID_Key\":1637715,\"EMP_NAME\":\"Sims, Jeryka | 3024108\"},{\"PID_Key\":1637610,\"EMP_NAME\":\"Wilder, Ashley | 3024097\"}],\"Table1\":[{\"ExceptCode\":\"BRKHR\",\"Description\":\"BRKHR - Approved Paid HR Break\"},{\"ExceptCode\":\"COACH\",\"Description\":\"COACH - Coachings, 1 on 1s, and reviews\"},{\"ExceptCode\":\"MEET\",\"Description\":\"MEET - All Meetings\"},{\"ExceptCode\":\"MEETOFFS\",\"Description\":\"MEETOFFS - Meeting at Offsite Location\"},{\"ExceptCode\":\"PROJ\",\"Description\":\"PROJ - SME, POC, and all other projects\"},{\"ExceptCode\":\"PROJOFFS\",\"Description\":\"PROJOFFS - Project at Offsite Location\"},{\"ExceptCode\":\"PROTIME\",\"Description\":\"PROTIME - SavePro – For SavePro Huddles and Coaching Only\"},{\"ExceptCode\":\"SYSTEM\",\"Description\":\"SYSTEM - Systems issues\"},{\"ExceptCode\":\"TRAIN\",\"Description\":\"TRAIN - Training Exception (not CBT)\"},{\"ExceptCode\":\"TRAIN_CBT\",\"Description\":\"TRAIN_CBT - Computer Based Training\"},{\"ExceptCode\":\"TRAINOFFS\",\"Description\":\"TRAINOFFS - Train at Offsite Location\"}],\"Table2\":[{\"Dept\":\"1\"}]}"}

阿贾克斯：

$.ajax({ 
     type: 'POST', 
     url: 'ExceptionServices.asmx/GetAgentsCodes', 
     contentType: "application/json; charset=utf-8", 
     data: '{"supPidKey":"' + supPidKey + '" }', 
     dataType: "json", 
     success: function (data) { 
      alert(data.d); 
      alert(data.d.Table); 
      $.each(data.d.Table, function (PID_Key, val) { 
      }); 
     }, 
     error: function (jqXHR, ajaxOptions, thrownError) { 
      alert(jqXHR.responseText); 
     } 
    });

C＃：

[WebMethod] 
    [ScriptMethod(ResponseFormat=ResponseFormat.Json)] 
    public string GetAgentsCodes(int supPidKey) 
    { 
     classes.ExceptionObject excObj = new classes.ExceptionObject(); 
     JavaScriptSerializer js = new JavaScriptSerializer(); 
     return js.Serialize(JsonMethods.ToJson(excObj.getAgentsCodes(supPidKey))); 
    } 

public static Dictionary<string, object> ToJson(DataSet data) 
     { 
      Dictionary<string, object> d = new Dictionary<string, object>(); 
      foreach (DataTable table in data.Tables) 
      { 
       d.Add(table.TableName, RowsToDictionary(table)); 
      } 
      return d; 
     }

如果其他人有类似的问题....我回答我自己的问题。在访问它之前需要解析我的成功函数中返回的数据。

success: function (data) { 
      var parsed = $.parseJSON(data.d); 
      $.each(parsed.Table, function (i, val) { 
       alert(val.PID_Key); 
      }); 
     },
