I'm trying to Deserialize object to list of object using JSON.NET lib. My json file is:
[
{
"id": 1,
"name": "Poczta",
"description": "Opis",
"latitude": 52.25197,
"longitude": 20.896355,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 2,
"name": "WAT",
"description": "Budynek główny - sztab.\r\nzażółć gęślą jaźń",
"latitude": 52.2531213,
"longitude": 20.8995849,
"accuracy": 0,
"type": "Uczelnia",
"image": null
},
{
"id": 3,
"name": "Przychodnia",
"description": "Opis",
"latitude": 52.250808,
"longitude": 20.895348,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 4,
"name": "DS3",
"description": "Opis",
"latitude": 52.250063,
"longitude": 20.895847,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 5,
"name": "DS2",
"description": "Opis",
"latitude": 52.2497674,
"longitude": 20.8966583,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 6,
"name": "DS1",
"description": "Opis",
"latitude": 52.25088,
"longitude": 20.897492,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 7,
"name": "DS4",
"description": "To jest opis",
"latitude": 52.2539982,
"longitude": 20.8971716,
"accuracy": 0,
"type": "",
"image": null
},
{
"id": 15,
"name": "a",
"description": "b",
"latitude": 52.250105,
"longitude": 20.896124,
"accuracy": 0,
"type": "Uczelnia",
"image": null
}
]
And I wrote some code to do that, but it doesn't work. I tried many options like dynamic deserialize and now i'm tried to make a list.
async private void webServiceGetPoints()
{
try
{
var client = new HttpClient();
var response = await client.GetAsync(new Uri("\\private\\"));
var result = await response.Content.ReadAsStringAsync();
List<WebServiceTag> convert = JsonConvert.DeserializeObject<List<WebServiceTag>>(result) as List<WebServiceTag>;
Debug.WriteLine(convert.Count);
}
catch (JsonSerializationException jsonerr)
{
Debug.WriteLine(jsonerr.ToString());
}
catch (Exception e)
{
Debug.WriteLine(e.ToString());
}
}
This code based on my own class with is:
class WebServiceTag
{
[JsonProperty("id")]
public int id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("description")]
public string description { get; set; }
[JsonProperty("latitude")]
public double latitude { get; set; }
[JsonProperty("longitude")]
public double longitude { get; set; }
[JsonProperty("accuracy")]
public int accuracy { get; set; }
[JsonProperty("type")]
public string type { get; set; }
[JsonProperty("image")]
public string image { get; set; }
}
I found that trying to use:
JsonConvert.DeserializeObject<List<T>>()
wouldn't work for me. I found that this worked instead.
JsonConvert.DeserializeObject<IEnumerable<T>>()
Hope its a better late than never answer.
If work for u... like it
List<modelCasa> objList = JsonConvert.DeserializeObject<List<modelCasa>>(json);
Response Body Class>>>
public class RestResponse
{
public string status { get; set; }
}
post Body Class>>>
class Customer_List
{
public string phone { get; set; }
}
in Void >>>>
Customer_List send= new Customer_List
{
phone= "***"
};
//
string json = JsonConvert.SerializeObject(send);
//
var client = new RestClient("http://localhost:1959/***");
var request = new RestRequest();
//
request.Method = Method.POST;
request.AddHeader("Accept", "application/json");
request.Parameters.Clear();
request.AddParameter("application/json", json,
ParameterType.RequestBody);
//
var response = client.Execute(request);
var content = response.Content;
it's answer for me !
var resp = JsonConvert.DeserializeObject<List<RestResponse>>(content);

I have doubt about how creating a class for receiving the response from HttpWebResponse.
The code I use for receiving a json response is:
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
ResJson myojb = (ResJson )js.Deserialize(objText, typeof(ResJson ));
}
}
The json I receive is:
{
"name": "Rube Goldberg Machine Stage 1",
"published": true,
"description": "<p>.STEP Version\n<br /><br>Rube Goldberg Experiment</p>",

"cached_slug": "stl"

{

"cached_slug": "rendering"
}
]
}
When creating the ResJson class I can not figure out how set softwares variable type.
How should it be declared?
public class Software
{
[JsonProperty("name")]
public string Name {get;set;}
[JsonProperty("cached_slug")]
public string CachedSlug {get;set;}
}
And then in your ResJson:
{
...
[JsonProperty("softwares")]
public List<Software> Softwares {get;set;}
...
}

I have generated classes from json2csharp
public class From

}
public class Chat

public string username { get; set; }
}
public class Entity
{
public string type { get; set; }
public int offset { get; set; }
public int length { get; set; }
}
public class Message
{
public int message_id { get; set; }
public From from { get; set; }
public Chat chat { get; set; }
public int date { get; set; }
public string text { get; set; }
public List<Entity> entities { get; set; }
}
public class Result
{
public int update_id { get; set; }
public Message message { get; set; }
}
public class RootObject
{
public bool ok { get; set; }
public List<Result> result { get; set; }
}
using newtonsoft to deserialization
var d = Newtonsoft.Json.JsonConvert.DeserializeObject(rcvd_data);
what to do next? how to put this all at work? I am confused please help.
To deserialization use this code:
RootObject ro = JsonConvert.DeserializeObject<RootObject>(rcvd_data);
And in ro you have all data.
EXAMPLE
bool ok = ro.ok;
foreach(Result r in ro.result)
{
int uId = r.update_id;
Message m = r.message;
int msgId = m.message_id;
}
string data = #"{""ok"":true,""result"":[{""update_id"":920493886,...";
RootObject ro = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(data);
foreach (Result result in ro.result)
{
//two example fields
Console.WriteLine("update_id= " + result.update_id);
Console.WriteLine("message text= "+result.message.text);
}
Based on: https://yts.am/api/v2/list_movies.json (Source: https://yts.am/api)
I used: http://json2csharp.com/ to create classes
Copy and paste the result of the get request of postman to json2csharp to automatically create the classes that you need
And once created, i used them on a Service like this:
private string URL = "https://yts.am/api/v2/list_movies.json";
public async Task<List<Movie>> GetMovies()
{
var httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(URL);
RootObject lista = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
List<Movie> todoes = lista.data.movies;
return todoes;
}
I'm using Newtonsoft.Json
Try this way
var d = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(rcvd_data);
then d will contain list of RootObject. By iterating using foreach you can get all the properties of RootObject model

I am trying to deserialize it with the following code and object classes
var response = _client.Execute(request);
var converter = new JsonDeserializer();
var menu = converter.Deserialize<PosMenu>(response);
PosMenu
[DataContract]
public class PosMenu
{
[DataMember]
public int VenueId { get; set; }
[DataMember]
public int count { get; set; }
[DataMember]
public PosMenuEmbedded _embedded { get; set; }
}
PosMenuEmbedded
[DataContract]
public class PosMenuEmbedded
{
[DataMember]
public long UniqueId { get; set; }
[DataMember]
public PosMenuCategory[] categories { get; set; }
[DataMember]
public int PosMenuId { get; set; }
}
PosMenuCategory
[DataContract]
public class PosMenuCategory
{
}
Note: I have taken all properties out of this class for now just to see if I could get it working with a blank class, but alas not.
If I comment out the line in PosMenuEmbedded
public PosMenuCategory[] categories { get; set; }
It succeeds. If I put it back in, it fails, even with an empty class.
Can anyone suggest why this might be?
[DataMember]
public List<PosMenuCategory> categories { get; set; }
im facing a problem with probably selfreference Looping:

public class ProtectedAccountMember

public int Id { get; set; }
[StringLength(300)]
public string Name { get; set; }

public virtual ProtectedAccount ProtectedAccount { get; set; }
}
Controller:
[ResponseType(typeof(ProtectedAccount))]
[Route("ProtectedAccounts/{id}/Members")]
[HttpGet]
public IHttpActionResult GetProtectedAccountMembers(int id)
{
var protectedAccount = db.ProtectedAccounts.Find(id);
if (protectedAccount == null)
{
return NotFound();
}
return Ok(protectedAccount.Members.ToList());
}
the data wich i receive for an GET seems to Loop recursive through all navigations:

There is only one "ProtectedAccount" in the database. DO i have to use DTO to overcome this issue? I tried some configuration via the json formatsettings but didnt get any better results.
From your code, you are only returing the protectedAccount.Members, hence you could do a projection query as below
var results = ctx.ProtectedAccountMembers
.Where(member => member.ProtectedAccount.Id == protectedAccount.Id)
.Select(member => new { member.Id, member.Name }).ToList();
I'm currently trying to read Json file (named initial_data.json) which reside in the folder DataModels in my Project folder. The problem I'm having is it won't read the file. I have tried the following code to read the file to json string (which I will use it to deserialize later, so I've tried to display it into resultTextBlock) and nothing has came out.
Here's my Json file format
{
"brands": [
{
"id": "AUD",
"name": "AUDI",
"sort": "99",
"active": true
},
{
"id": "BEN",
"name": "MERCEDES-BENZ",
"sort": "6",
"active": true
},
{
"id": "BMW",
"name": "BMW",
"sort": "7",
"active": true
},
{
"id": "CHE",
"name": "CHEVROLET",
"sort": "8",
"active": true
}
],
"models": [
{
"id": "100",
"name": "CIVIC",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "101",
"name": "CRV",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "102",
"name": "CRVEXI",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "103",
"name": "GDYSSEY",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
}
]
}
Here's my json Class
public class Brand
{
[JsonProperty("id")]
public string id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("sort")]
public string sort { get; set; }
[JsonProperty("active")]
public bool active { get; set; }
[JsonProperty("path")]
public string path { get; set; }
}
public class Model
{
[JsonProperty("id")]
public string id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("brandID")]
public string brandID { get; set; }
[JsonProperty("size")]
public object size { get; set; }
[JsonProperty("year")]
public string year { get; set; }
[JsonProperty("active")]
public bool active { get; set; }
}
And here's how I write my reading function
private async Task readJsonAsync()
{
// Notice that the write **IS** identical ... except for the serializer.
string content = String.Empty;
var myStream = await ApplicationData.Current.LocalFolder.OpenStreamForReadAsync(JSONFILENAME);
using (StreamReader reader = new StreamReader(myStream))
{
content = await reader.ReadToEndAsync();
}
resultTextBlock.Text = content;
}
Any help would be appreciated
think there might be some issue with the path you specified for the file name.
Please put your file in assets folder and follow the below code
var fileStream = File.OpenRead("Assets/" + "sampleJson.txt");//You can specify your file name here.
using (StreamReader reader = new StreamReader(fileStream))
{
var content = await reader.ReadToEndAsync();
}
