jQuery/ASMX：在C＃中反序列化JSON時出錯＃

Question

我正在對C＃ASMX網絡方法做AJAX POST，但無法獲取JSON數據反序列化。這應該工作，但是是給我下面的錯誤...

{"Message":"Cannot convert object of type \u0027System.String\u0027 to type \u0027System.Collections.Generic.IDictionary`2[System.String,System.Object]\u0027","StackTrace":" at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object\u0026 convertedObject)\r\n at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object\u0026 convertedObject)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"} 

這裏是的WebMethod ...

[WebMethod] 
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
    public void SaveProfileProperties(string data) 
    { 
     ups.Credentials = System.Net.CredentialCache.DefaultCredentials; 
     try 
     { 
      System.IO.File.WriteAllText(@"E:\Log.txt", data); 
     } 
     catch { } 

     var json = new JavaScriptSerializer(); 
     Dictionary<string, string> props = json.Deserialize<Dictionary<string, string>>(data); 
     SaveSQLData(props); 
    } 

這裏是正在發送數據...

"{data:{\"userName\":\"Doe\",\"UserProfile_GUID\":\"\",\"AccountName\":\"Domain\\Doe\",\"FirstName\":\"John\",\"LastName\":\"Doe\",\"PreferredName\":\"John Doe\",\"WorkPhone\":\"2176\",\"Department\":\"PHI\",\"Title\":\"Director\",\"SPS-JobTitle\":\"Director\",\"Manager\":\"Domain\\jdoe\",\"PersonalSpace\":\"/my/personal/Doe/\",\"PictureURL\":\"Doe_MThumb.jpg\",\"UserName\":\"Doe\",\"SPS-ClaimProviderID\":\"Windows\",\"SPS-ClaimProviderType\":\"Windows\",\"SPS-SavedAccountName\":\"Domain\\Doe\",\"SPS-DistinguishedName\":\"CN=John Doe,CN=Users,DC=domain,DC=local\",\"SPS-LastKeywordAdded\":\"1/2/2014 12:00:00 AM\",\"WorkEmail\":\"Doe@domain.com\",\"CellPhone\":\"5555555555\",\"Office\":\"C28\",\"SPS-TimeZone\":\"WF_Service.UPS.SPTimeZone\",\"personalEmail\":\"Doe.John@gmail.com\",\"SPS-EmailOptin\":\"0\",\"empID\":\"224\",\"team\":\"A\",\"p_id\":\"224\",\"username\":\"Doe\",\"last_name\":\"Doe\",\"first_name\":\"John\",\"birthday\":\"1/2/1985 12:00:00 AM\",\"anniv\":\"6/4/2007 12:00:00 AM\",\"imageurl\":\"A0BB.jpg\",\"Position\":\"Director\",\"dept_started_in\":\"IT\",\"birthplace\":\"NC\",\"marital_status\":\"Married\",\"sports_team\":\"Sporty Sports\",\"last_school\":\"None\",\"hobbies\":\"\",\"pets\":\"\",\"prior_employer\":\"None\",\"resides_in\":\"USA\",\"quote\":\"「Where you live should not determine whether you live, or whether you die.」 -- Bono\",\"fav_color\":\"009933\"}}" 

更新：這是客戶端。經過一些測試後，我發現在帖子開頭的堆棧跟蹤錯誤實際上是客戶端。

更新2：原來，JSON序列化在客戶端發生故障。這裏是準備數據的正確方法...

json.Stringify({data:{\"userName\":\"Doe\",\"UserProfile_GUID\":\"\",\"AccountName\":\"Domain\\Doe\",\"FirstName\":\"John\",\"LastName\":\"Doe\",\"PreferredName\":\"John Doe\",\"WorkPhone\":\"2176\",\"Department\":\"PHI\",\"Title\":\"Director\",\"SPS-JobTitle\":\"Director\",\"Manager\":\"Domain\\jdoe\",\"PersonalSpace\":\"/my/personal/Doe/\",\"PictureURL\":\"Doe_MThumb.jpg\",\"UserName\":\"Doe\",\"SPS-ClaimProviderID\":\"Windows\",\"SPS-ClaimProviderType\":\"Windows\",\"SPS-SavedAccountName\":\"Domain\\Doe\",\"SPS-DistinguishedName\":\"CN=John Doe,CN=Users,DC=domain,DC=local\",\"SPS-LastKeywordAdded\":\"1/2/2014 12:00:00 AM\",\"WorkEmail\":\"Doe@domain.com\",\"CellPhone\":\"5555555555\",\"Office\":\"C28\",\"SPS-TimeZone\":\"WF_Service.UPS.SPTimeZone\",\"personalEmail\":\"Doe.John@gmail.com\",\"SPS-EmailOptin\":\"0\",\"empID\":\"224\",\"team\":\"A\",\"p_id\":\"224\",\"username\":\"Doe\",\"last_name\":\"Doe\",\"first_name\":\"John\",\"birthday\":\"1/2/1985 12:00:00 AM\",\"anniv\":\"6/4/2007 12:00:00 AM\",\"imageurl\":\"A0BB.jpg\",\"Position\":\"Director\",\"dept_started_in\":\"IT\",\"birthplace\":\"NC\",\"marital_status\":\"Married\",\"sports_team\":\"Sporty Sports\",\"last_school\":\"None\",\"hobbies\":\"\",\"pets\":\"\",\"prior_employer\":\"None\",\"resides_in\":\"USA\",\"quote\":\"「Where you live should not determine whether you live, or whether you die.」 -- Bono\",\"fav_color\":\"009933\"}}
