I have below JSON input for My azure function but unable to pass it in after deserialize object
{
"name": [{
"SiteName": "Site1",
"SiteUrl": "https://site1.com/"
},
{
"SiteName": "Site2",
"SiteUrl": "https://site2.com/"
},
]
}
after deserialize I am getting count as 2 but inside array value I am not getting for deserializing using below code
string requestBody = new StreamReader(req.Body).ReadToEnd();
dynamic data = JsonConvert.DeserializeObject(requestBody);
var Root = data["name"].ToObject<List<Constant>>();
and for Constant class declared like below
class Constant
{
public Dictionary<string, string> name { get; set; }
}
Try to create class like below.
class JsonResponse
{
public List<Constant> name { get; set; }
}
class Constant
{
public string SiteName { get; set; }
public string SiteUrl { get; set; }
}
And try to Deserialize response with JsonConvert.DeserializeObject<JsonResponse>(requestBody).
string requestBody = new StreamReader(req.Body).ReadToEnd();
JsonResponse data = JsonConvert.DeserializeObject<JsonResponse>(requestBody);
var Root = data.name;
Solution 1: Deserialize as object list
The model class should be:
public class Site
{
public string SiteName { get; set; }
public string SiteUrl { get; set; }
}
And deserialize as below:
var Root = data["name"].ToObject<List<Site>>();
Sample program (Site class)
Solution 2: Deserialize as Dictionary
var Root = data["name"].ToObject<List<Dictionary<string, string>>>();
Sample program (Dictionary)
I have a list of objects in below json format. I would like to deserialize using below code. It is throwing unable to convert to object error. I have tried below three options, but didnt help. jsoninput is a IEnumerable<string>converted into json object using ToJson().
Error:
{"Error converting value \"{\"id\":\"11ef2c75-9a6d-4cef-8163-94daad4f8397\",\"name\":\"bracing\",\"lastName\":\"male\",\"profilePictureUrl\":null,\"smallUrl\":null,\"thumbnailUrl\":null,\"country\":null,\"isInvalid\":false,\"userType\":0,\"profilePrivacy\":1,\"chatPrivacy\":1,\"callPrivacy\":0}\" to type 'Api.Models.UserInfo'. Path '[0]', line 1, position 271."}
var requests1 = JsonConvert.DeserializeObject<UsersInfo>(jsoninput);
var requests2 = JsonConvert.DeserializeObject<IEnumerable<UserInfo>>(jsoninput);
var requests3 = JsonConvert.DeserializeObject<List<UserInfo>>(jsoninput);
//Below are my classes,
public class UsersInfo
{
public List<UserInfo> UserInfoList { get; set; }
public UsersInfo()
{
UserInfoList = new List<UserInfo>();
}
}
public class UserInfo
{
public string Id { set; get; }
public string Name { set; get; }
public string LastName { set; get; }
public string ProfilePictureUrl { set; get; }
public string SmallUrl { set; get; }
public string ThumbnailUrl { get; set; }
public string Country { set; get; }
public bool IsInvalid { set; get; }
}
Below is my json object,
["{\"id\":\"11ef2c75-9a6d-4cef-8163-94daad4f8397\",\"name\":\"bracing\",\"lastName\":\"male\",\"profilePictureUrl\":null,\"smallUrl\":null,\"thumbnailUrl\":null,\"country\":null,\"isInvalid\":false}","{\"id\":\"318c0885-2720-472c-ba9e-1d1e120bcf65\",\"name\":\"locomotives\",\"lastName\":\"riddles\",\"profilePictureUrl\":null,\"smallUrl\":null,\"thumbnailUrl\":null,\"country\":null,\"isInvalid\":false}"]
Looping through individual items in json input and if i deserialize it like below, it works fine. But i want to deserialize the list fully. Note: jsoninput was a IEnumerable<string> before i convert in json object.
foreach (var re in jsoninput)
{
var request0 = JsonConvert.DeserializeObject<UserInfo>(re);
}
Please look at this fiddle: https://dotnetfiddle.net/XpjuL4

Both work, and are basically very close to what you are doing. You can either serialize it as a list (based on your json, I think that's the closest to your use case, and that's Option 2).
However, put extra attention to the JSON. I had to re-parse your JSON to make it work (https://jsonformatter.org/json-parser is a nice website to do it). For the sake of explaining the example, in C#, # means raw string, and in raw string, quotes are escaped with double quotes "".
I would expect that the business logic generating this JSON is not correct, if the JSON you pasted is the direct result from it.
EDIT
Given the OP's comment:
Thanks Tu.ma for your thoughts. The other method returns
IEnumerable which is nothing but
Dictionary.Where(x => x.Value == null).Select(x =>
x.Key).ToHashSet(). The values in Dictionary are -> Key
is String, Value is UserInfo object serialized. So, in that case i
should deserialize one by one? If not, i should serialize entire list
in one shot? Am i right? – Raj 12 hours ago
The problem is in the way you are generating the list of UsersInfo. The result from Dictionary<string,string>.Where(x => x.Value == null).Select(x =>
x.Key).ToHashSet() is a bunch of strings, not of objects, so you need to serialize them one by one.
If you are worried about the linearity of the approach, you could consider running through it in parallel. Of course, you need to judge if it fits your application.
var userInfoStrings = Dictionary<string,string>.Where(x => x.Value == null).Select(x => x.Key).ToHashSet();
var UserInfoList = userInfoStrings.AsParallel().Select (u => JsonConvert.DeserializeObject<UsersInfo>(u)).ToList();
The JSON data is as follows：

I want to use c # extraction
"UserID": 3974854,
"UserCharm": 114858,
"UserName": "jack",
"UserID":6231512,
"UserCharm":22644,
"UserName":"red.girl",
That is to extract UserID, UserCharm, UserName，This json has many layers,
What I want after the extraction is，id is sorted in order
id = 1, UserID = 3974854, UserCharm = 114858, UserName = jack
id = 2, UserID = 6231512, UserCharm = 22644, UserName = red.girl
I use the following code, but only extract the first one
string json = #"{"Sucess":true,"Code":0,"Msg":"Sucess","Data":{"UserDayRanking":{"UserID":11452112,"UserCharm":0,"UserName":"gay","UserGender":1,"UserLevel":36,"UserPhoto":"http://res.xxx.com/2020/3/16/63719926625601201487545U11452112.jpeg","Ranking":0,"IsNobility":0,"NobilityType":0,"NobilityLevel":0,"UserShowStyle":null,"LiveLevelUrl":null,"IsStealth":false},"DayRankingList":[{"UserID":3974854,"UserCharm":114858,"UserName":"jack","UserGender":1,"UserLevel":91,"UserPhoto":"http://res.xxx.com/2020/2/15/63717400601924412312384U3974854.jpeg","Ranking":2,"IsNobility":1,"NobilityType":1,"NobilityLevel":3,"UserShowStyle":{"NameColor":100102,"BorderColor":100403,"LiangMedal":0,"DztCountDown":0,"Mounts":100204,"LiveLevelCode":0,"LiveRights":null},"LiveLevelUrl":null,"IsStealth":false},{"UserID":6231512,"UserCharm":22644,"UserName":"red.girl","UserGender":1,"UserLevel":57,"UserPhoto":"http://res.xxx.com/2019/11/20/63709843050801519858823U6231512.jpeg","Ranking":3,"IsNobility":0,"NobilityType":0,"NobilityLevel":0,"UserShowStyle":{"NameColor":0,"BorderColor":0,"LiangMedal":0,"DztCountDown":0,"Mounts":0,"LiveLevelCode":0,"LiveRights":null},"LiveLevelUrl":null,"IsStealth":false}],"LiveCharmSwitch":1,"IsSelf":false}}";
List<Info> jobInfoList = JsonConvert.DeserializeObject<List<Info>>(z);
foreach (Info jobInfo in jobInfoList)
{
//Console.WriteLine("UserName:" + jobInfo.UserName);
}
public class Info
{
public string UserCharm { get; set; }
public string UserName { get; set; }
public data DayRankingList { get; set; }
}
public class data
{
public int UserID { get; set; }
public string UserCharm { get; set; }
public string UserName { get; set; }
public string UserGender { get; set; }
public string UserLevel { get; set; }
}
The above code only shows username = jack，Never show username = red.girl
As it looks to me then you want some details from your JSON has the which is in DayRankingList. As you only want some data then we can use a tool like http://json2csharp.com/ to create our classes and then remove what we don't need. Then we end up with the following classes.
public class DayRankingList
{
public int UserID { get; set; }
public int UserCharm { get; set; }
public string UserName { get; set; }
}
public class Data
{
public List<DayRankingList> DayRankingList { get; set; }
}
public class RootObject
{
public Data Data { get; set; }
}
Which you can deserialise like this
string json = .....
var root = JsonConvert.DeserializeObject<RootObject>(json);
Then if you wish, you can extract the inner data into a new List<> and then just work on that.
List<DayRankingList> rankingLists = root.Data.DayRankingList;
//Do something with this, such as output it
foreach(DayRankingList drl in rankingLists)
{
Console.WriteLine(String.Format("UserId {0} UserCharm {1} UserName {2}",drl.UserId, drl.UserCharm, drl.UserName));
}
You can use Json.Linq to parse your JSON into JObject and enumerate DayRankingList items (since it's an array). Then convert every item into data class and order the result sequence by UserID
var jObject = JObject.Parse(json);
var rankingList = (jObject["Data"] as JObject)?.Property("DayRankingList");
var list = rankingList.Value
.Select(rank => rank.ToObject<data>())
.OrderBy(item => item?.UserID);
foreach (var user in list)
Console.WriteLine($"{user.UserID} {user.UserName}");
Another way is copy your JSON, go to Edit->Paste Special->Paste JSON as classes menu in Visual Studio and generate a proper class hierarchy (I've got 5 classes, they are quite long to post here), then use them during deserialization
The most type-safe way is to define the class structure that you want, like jason.kaisersmith suggested.
To have the final format you need, though, you might want to do an extra Linq Order and Select, to include the id:
var finalList = rankingLists.OrderBy(rl => rl.UserId).Select((value, index) => new
{
id = index,
value.UserId,
value.UserCharm,
value.UserName
});
foreach (var drl in finalList)
{
Console.WriteLine($"Id = {drl.id}, UserId = {drl.UserId}, UserCharm = {drl.UserCharm}, UserName = {drl.UserName}");
}
I have one concrete class called ShipFromAddress and where I am deserializing my json this below way
JavaScriptSerializer jss = new JavaScriptSerializer();
oShipFromAddress = jss.Deserialize<ShipFromAddress>(Request.Cookies["ShipFromAddress"].Value);
Concrete class
public class ShipFromAddress
{
public string Weight
{
get;
set;
}
public string addressLine1
{
get;
set;
}
public string addressLine2
{
get;
set;
}
public string city
{
get;
set;
}
public string postcode
{
get;
set;
}
public string countrycode
{
get;
set;
}
public string StateCode
{
get;
set;
}
}
I do not want to create or use concrete class rather I want to do that deserialization on the fly with the help of dynamic object or anonymous class concept. Please guide me with sample code.
i got two solution.....which looks good
1) when need to pass multiple data serialize to anonymous the example would be
var query = from employee in employees select new { Name = employee.Name, Id = employee.Id };
LogEmployees(query);
public void LogEmployees (IEnumerable<dynamic> list)
{
foreach (dynamic item in list)
{
string name = item.Name;
int id = item.Id;
}
}
method argument type must be IEnumerable<dynamic> because LogEmployees() function expecting multiple data
2) when passing single data the code look like
public class Program
{
private static void Thing(dynamic other)
{
Console.WriteLine(other.TheThing);
}
private static void Main()
{
var things = new { TheThing = "Worked!" };
Thing(things);
}
}
With JavaScriptSerializer you can use the DeserializeObject method from serializer which will return just an object:
JavaScriptSerializer jss = new JavaScriptSerializer();
object obj= jss.DeserializeObject(Request.Cookies["ShipFromAddress"].Value);
Internally it will be represented as a Dictionary<string, object>, so you can cast it to it and use like this:
var values = (Dictionary<string, object>)jss.DeserializeObject(Request.Cookies["ShipFromAddress"].Value);
var addressLine1 = values["addressLine1"].ToString();
Or you can cast it to dynamic:
dynamic values = jss.DeserializeObject(Request.Cookies["ShipFromAddress"].Value);
var addressLine1 = values["addressLine1"].ToString();
Alternatively, You can use Json.NET library and it's JsonConvert class (benchmarks show that it performs faster than JavaScriptSerializer). The code will look like this:
dynamic values = JsonConvert.DeserializeObject(Request.Cookies["ShipFromAddress"].Value);
var addressLine1 = values.addressLine1;
I use Newtonsoft.Json
string source = Request.Cookies["ShipFromAddress"].Value as string;
var address = JsonConvert.DeserializeObject<ShipFromAddress>(source);
My application is asp.net. I have to send some values back to server. For this I create a object serialize it and send it to server. At server I try to de-serialize it
Following is my code
[Serializable]
public class PassData
{
public PassData()
{
}
public List<testWh> SelectedId { get; set; }
public string SelectedControlClientId { get; set; }
public string GroupTypeId { get; set; }
public string SectionTypeId { get; set; }
}
[Serializable]
public class testWh
{
public testWh()
{
}
public string Id { get; set; }
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
//this can not serialize the SelectedId and the count remains 0
PassData data = serializer.Deserialize<PassData>(jsonString);
//this serialize in an anonymous object with key value pair
var data2 = serializer.DeserializeObject(textHiddenArguments.Text);
Following is my Json Serialized String
{
"SelectedId":{"0":"ABCD","1":"JKLM"},
"SelectedControlClientId":"YTUTOOO",
"GroupTypeId":3,
"SectionTypeId":"1"
}
quotes escaped string
"{\"SelectedId\":{\"0\":\"ABCD\",\"1\":\"JKLM\"},\"SelectedControlClientId\":\"YTUTOOO\",\"GroupTypeId\":3,\"SectionTypeId\":\"1\"}"
My Problem is Selected Id is array of testWH object. But when I try to desrialize it, the SelectedId property of PassData which is list does not get serialized and count remains zero.
I tried using array instead of List, which gave an exception "no parameter less constructor..."
Could any one explain the what I am doing wrong here ?
The key problem here is that the JSON doesn't match the objects you have constructed. You can see this by writing the data you want and serializing:
var obj = new PassData
{
SelectedId = new List<testWh>
{
new testWh { Id = "ABCD"},
new testWh { Id = "JKLM"}
},
GroupTypeId = "3",
SectionTypeId = "1",
SelectedControlClientId = "YTUTOOO"
};
string jsonString = serializer.Serialize(obj);
which gives JSON like:
{"SelectedId":[{"Id":"ABCD"},{"Id":"JKLM"}],
"SelectedControlClientId":"YTUTOOO","GroupTypeId":"3","SectionTypeId":"1"}
So now you need to decide which you want to change; the JSON or the classes. The following alternative class works fine with your original JSON, for example:
public class PassData
{
public Dictionary<string,string> SelectedId { get; set; }
public string SelectedControlClientId { get; set; }
public string GroupTypeId { get; set; }
public string SectionTypeId { get; set; }
}
