Jackson - Deserialize nested JSON
I see couple of problems in your code. First thing is that you don't have report attribute in your Response class, which is required as per the json structure you have shown. Secondly you need to provide the getters and setters in your bean classes as those will be used by the jackson for marhsalling and unmarshalling of json/object.

JSON Deserialization Despair (unable to deserialize nested types)
I haven't done what you are doing before, but judging by the documentation, I'd assume the following would work: List<Type> types = new List<Type>(); types.Add(typeof(Person)); types.Add(typeof(Language)); types.Add(typeof(Secretary)); DataContractJsonSerializer dc = new DataContractJsonSerializer(typeof(PeopleObject), types); PeopleObject p = (PeopleObject)dc.ReadObject(response); You basically need to tell the Serializer all the types it may encounter while serializing/deserializing your object.

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type with complex and nested objects
According to your JSON data, the objects that you need to map to have to look like this (unless you have your own JsonDeserializer of course): public class Banner { public string LocationCodeString { get; set; } public int LocationCodeInt { get; set; } public string MediaUrl { get; set; } } public class CampaignWithChosenProposal { public List<Banner> Banners { get; set; } public string Code { get; set; } public string CustomerInstruction { get; set; } public string InfoLink { get; set; } public string LobbySubTitle { get; set; } public string LobbyTitle { get; set; } public string MoreText { get; set; } public int NumOfColumns { get; set; } public int NumOfRows { get; set; } public string OriginString { get; set; } public int

Nested Json Lists formatting incorrectly
The issue is not really in removing the u from the start of those strings. The easiest way to do this is to import the json module and call json.dumps(checklist.json()['list']). It will do the right thing for you. The strings the json module returns are unicode objects (and are represented in the repr) as unicode literals. To "remove" them you need to handle the unicode strings better and this is the easiest way that will result in the least hair pulling and most forward compatibility with python 3.

JSON serializer with nested object lists
Turns out you don't need to use a serializer at all. You just return type object. public object NavigationItems() { using (TTConnection connection = new TTConnection("ClientDb")) { if (MySession.Current.MyClub == null) return USER_ERROR; MiddleTier.WebNavigation.WebNavigationGenerator gen = MySession.Current.NavGenerator; List<NavigationElement> list = gen.GetNavigation(); return list; } }

How to insert nested lists (or nested block elements) into RichTextBlock?
Ok Ill start with silverlight. There was a TreeView Control in silverlight that would have exactly solved your problem. Link to tree view example But since we already know that winRt is a subset of API's these controls have been removed for metro app. More over microsofts design policy regarding the Type Of scenario you are mentioning has changed to : Semantic Zoom For Metro Apps So i advise if your app requirement is like that Either go with the richtextbox or use Grids with Rows and columns Which ever suits your coding best. One more way is to use third party library for tree structure . Syncfusion tree control Syncfusion has a tree control you can try out in the Demo. Even there are more third party tool but none are free not even he above one. Please Let me know if any more co

Deserialize multiple JSON arrays into separate C# datasets/datatables using JSON.net (newtonsoft)
This doesn't answer the question exactly because I personally don't see why you would want to deserialize into datasets when the json.NET model is more oriented around deserializing into objects. Here it is; public class TheJson { public string status { get; set; } public client[] clients { get; set; } public dossier[] dossiers { get; set; } } public class client { public string ClientID { get; set; } public string Fullname { get; set; } public bool Inactive { get; set; } } public class dossier { public string CreateDate { get; set; } public string DossierName { get; set; } } With those definitions it's as simple as; TheJson clientsAndDossiers = JsonConvert.DeserializeObject<TheJson>(_jsonresp); Now with regard to your last comment, to ap

Deserialize JSON Data - Custom Deserialization Using Jackson JSON Parser
UPDATED Among other things, you are mixing up the two aproaches to read a JSON stream: using readTree() to get all your JSON data in a memory tree (like XML's DOM) but also using a JsonParser to read a JSON stream token by token (like XML's JAX). The following is a method that does almost the same using readTree(), which seems to be more appropriate to you as you are reading JSON already loaded in a String: public List<VehicleInformationBean> getAllVehiclesInTree(String response) { List<VehicleInformationBean> vehicleList = new ArrayList<VehicleInformationBean>(); try { PersonInformationBean mPersonInformationBean; DatabaseHelper mDatabaseHelper = DatabaseHelper.getInstance(sContext); ObjectMapper mapper = new ObjectMapper(); O

Very simple attempt to deserialize JSON with JSON.NET does not work
Your JSON has more than one object, and neither are in an array. You either need to remove one of the objects from the JSON or add them to an array and deserialize them properly: string responseBody = @"[ {""HighScoreId"":1,""Name"":""Debra Garcia"",""Score"":2.23}, {""HighScoreId"":2,""Name"":""Thorsten Weinrich"",""Score"":2.65} ]"; var highScores = JsonConvert.DeserializeObject<List<GlobalHighScore>>(responseBody);

Deserialize the JSON where the values are field names with JSON.NET
You can create a custom JsonConverter which serializes/deserializes Role[]. You can then decorate your Roles property with the JsonConverterAttribute like this: public class User { public string Name { get; set; } [JsonConverter(typeof(RolesConverter))] public Role[] Roles { get; set; } } In your converter class you are able to read an object and return an array instead. Your converter class may look like this: class RolesConverter : JsonConverter { public override bool CanConvert(Type objectType) { return objectType == typeof(Role[]); } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { // deserialize as object var roles = serializer.Deserialize<JObject>(r

The javascript Date object is something that is not serializable by .Net, what you do is fix the date before you transfer your object: function fixDate(date) { if (date != undefined && date != null && date.getDate) { var curr_date = date.getDate(); var curr_month = date.getMonth() + 1; //Months are zero based var curr_year = date.getFullYear(); date = curr_date + "/" + curr_month + "/" + curr_year; date = date.replace(/d/g, '0$&'); } return date; } this code is for the "dd/MM/yyyy" format , but you can format it how ever you like. remember to choose the specific format in your server as well

How to Deserialize JSON string?
The secret is to keep your deserialized JSON in the most general form possible: Dictionary<string, object> theData= new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(jsonString); System.Collections.ArrayList dData= (System.Collections.ArrayList)theData["DData"]; foreach (Dictionary<string, object> data in dData) { string date = (string)data["Date"]; Dictionary<string, object> cZeroNode = (Dictionary<string, object>)data["C0"]; string d = (string)cZeroNode["D"]; string id = (string)cZeroNode["Id"]; } The call to Deserialize() creates a tree of Dictionary<string, object> that you can traverse at will.

How to Deserialize JSON data?
You can deserialize this really easily. The data's structure in C# is just List<string[]> so you could just do; List<string[]> data = JsonConvert.DeserializeObject<List<string[]>>(jsonString); The above code is assuming you're using json.NET. EDIT: Note the json is technically an array of string arrays. I prefer to use List<string[]> for my own declaration because it's imo more intuitive. It won't cause any problems for json.NET, if you want it to be an array of string arrays then you need to change the type to (I think) string[][] but there are some funny little gotcha's with jagged and 2D arrays in C# that I don't really know about so I just don't bother dealing with it here.

JSON.Net Deserialize MailAddress
I think the problem is that your ReadJson method leaves the reader incorrectly positioned when it is finished, thus messing up the rest of the deserialization process. Think of the reader like a forward-only cursor for the JSON data. When ReadJson gets called, it is positioned such that it is just about to read the next item that the converter said it can handle. In the case of your EmailConverter, it would be positioned just about to read this portion of the JSON: { "DisplayName": "", "User": "jamesdean890", "Host": "fake.com.au", "Address": "jamesdean890@fake.com.au" } Since the converter is supposed to handle the entire Email object, it needs to consume all the JSON for that object. I think what is happening is the reader is not getting advanced to the closing brace. You

Deserialize JSON to Object
object_hook won't help you, since you have id and name on the different levels in the json string: object_hook, if specified, will be called with the result of every JSON object decoded and its return value will be used in place of the given dict. Let's see why object_hook won't help. If you print objects that are coming to the object_decoder function, you'll see that it is going up from the deep, like this: {u'name': u'bedroom'} {u'name': u'kitchen'} {u'1': None, u'2': None} None This means that you cannot join object_decoder calls in order to produce a Light instance. How about using custom JSONDecoder class instead: import json class Light: def __init__(self, id, name): self.id = id self.name = name response = '{"1": {"name": "bedroom"}, "2": {"na

How can I deserialize JSON i Silverlight?
You haven't specified what technologies you use, so I assume that this is a general question about how to parse JSON data in Silverlight. I have written a tutorial in my blog, it is for Windows Phone but will work in Silverlight too. Or you can use the example from MSDN documentation. A general algorithm would be like this: Create model classes with DataContract and DataMember attributes. Use the default serializer class so: new DataContractJsonSerializer(typeof(YourModel)) Parse the stream to your model class (YourModel)dcs.ReadObject(stream) If you have a string instead of a stream, you should convert it to an instance of MemoryStream, it is explained in MSDN documentation. Also you can use other silverlight libraries like JSON.Net for deserializing, but I haven't worked with them

python json.loads / json.load truncates nested json objects?

Deserialize JSON to type with different property name
Your web method is accepting a list of Persons, but that is not what you are passing from the client. You are passing an object that contains a list of persons. If you want it to work, you should just pass the list itself and not wrap it in an object. $.ajax({ type: "POST", url: "TestPage.aspx/GetData", data: '[{ "Name": "Me"}]', contentType: "application/json; charset=utf-8", dataType: "json", success: function () { alert("Data Submitted"); } }); Another alternative, if you can't change the client, is to change the server side to expect the wrapper object. Create a class to hold the list... class PersonListWrapper { public List<Person> persons { get; set; } } ...and change your web method to accept that class. [WebMethod] public stat

Exception when trying to deserialize the JSON object
Without knowing the exception details I can only guess, but looks like the problem is that you are creating an instance of the non-resizable memory stream and trying to write an updated object into it - probably the result of the serialization is larger than the original string and thus stream cannot accept it.

Deserialize JSON containing an anonymous function using .net
JSON is a data representation protocol, and as such it can only be used to represent data, not behavior (which is what functions are). As your deserializer told you, what you have is not valid JSON (it's a valid JavaScript object, though, which causes some confusion). Check the JSON spec for more details on this format. So to your question - no, you cannot deserialize JSON containing function, because it's not JSON in the first place.

How do I deserialize a JSON array using the Play API
I'm a bit rusty, so please forgive the mess. Perhaps another overflower can come in here and clean it up for me. This solution assumes that the JSON is an array of objects, and each of the objects contains exactly one key-value pair. I would highly recommend spicing it up with some error handling and/or pattern matching to validate the parsed JSON string. def deserializeJsonArray(ss: String): Map[String, JsValue] = { val jsObjectSeq: Seq[JsObject] = Json.parse(ss).as[Seq[JsObject]] val jsValueSeq: Seq[JsValue] = Json.parse(ss).as[Seq[JsValue]] val keys: Seq[String] = jsObjectSeq.map(json => json.keys.head) (keys zip jsValueSeq).toMap }

Using Json.NET to deserialize this kind of data
The short answer to your question, "why am I getting this error" is that your JSON is a mix of JSON objects and arrays, yet your code appears to be trying to deserialize everything into dictionaries. Json.Net can't deserialize an array into a dictionary, so it throws this error. When deserializing, you have to make sure to match JSON objects to .NET objects (or Dictionaries) and JSON arrays to .NET arrays (or Lists). So, how do we get things working? Well, if you just want a generic function that can handle any arbitrary JSON and convert it into regular .NET types (primitives, Lists and Dictionaries), then you can use JSON.Net's Linq-to-JSON API to do something like this: private static object Deserialize(string json) { return ToObject(JToken.Parse(json)); } private static object

how do deserialize this json string to class
This isn't working because you're trying to deserialize an array into an object. The json.NET deserializer will not be able make that conversion. Because your json arrays have multiple types in them you'll have to deserialize into the smallest common denominator, in this case, object. From there I would recommend writing a method to assign each index to it's corresponding property in WidgetProps. So basically, define this constructor; public WidgetProps(object[] props) { Visible = (bool)props[0]; DockState = (string)props[1]; // ext } I would have something like a WidgetDirty class that I do the initial deserilization into. From there you can create a new instance of WidgetLayout by instantiating each of it's properties like myWidgetLayoutInstance.Visits = new WidgetProp(m
