c# JSON array, running foreach on a nested dictionary - c#

Sorry for the very ambiguous title but I don't quite know the question I am asking and have spent a couple of hours reading questions on here and am none the wiser!
I have a json array which looks like this:
{
"terms": "http://www.xe.com/legal/dfs.php",
"privacy": "http://www.xe.com/privacy.php",
"from": "USD",
"amount": 1,
"timestamp": "2018-08-14T00:00:00Z",
"to": [
{
"quotecurrency": "EUR",
"mid": 0.8771637444
},
{
"quotecurrency": "GBP",
"mid": 0.7835914281
}
]
}
My code looks like this:
public class DeserializeEX
{
//public string Disclaimer { get; set; }
//public string License { get; set; }
public string Timestamp { get; set; }
public string From { get; set; }
public DeserializeEXto To;
}
public class DeserializeEXto
{
public Dictionary<string, double> To { get; set; }
}
The bit I can't work out now is how to access that dictionary when deserializing?
This obviously doesn't work because result4.To isn't the correct thing to look at:
var result4 = JsonConvert.DeserializeObject<DeserializeEX>(response);
foreach (KeyValuePair<string, double> entry4 in result4.To)
{
outputData.Rows.Add(result4.Timestamp, loadBaseCurr, entry4.Key, entry4.Value);
}


Your DeserializeEXto class is wrong, it should really look like this:
public class DeserializeEXto
{
public string QuoteCurrency { get; set; }
public double Mid { get; set; }
}
And the To property in the root class needs to be this:
public IEnumerable<DeserializeEXto> To { get; set; }
And now your loop will look something like this:
foreach (var entry4 in result4.To)
{
outputData.Rows.Add(result4.Timestamp, loadBaseCurr, entry4.QuoteCurrency, entry4.Mid);
}


I don't think your model matches your json. Main issue is that for your to, it's actually an object array, instead of a dictionary.
Try this model:
public class CurrencyDTO
{
public string Terms { get; set; }
public string Privacy { get; set; }
public string From { get; set; }
public double Amount { get; set; }
public DateTimeOffset Timestamp { get; set; }
public List<QuoteCurrencyDTO> To { get; set; }
}
public class QuoteCurrencyDTO
{
public string QuoteCurrency { get; set; }
public double Mid { get; set; }
}

Deserialize json to List<object> in C#

I have the following JSON string
{
"data": [
{
"symbol": "1COV.GE",
"exposure": "0",
"makerExposure": "-2028",
"takerExposure": "2028",
"makerPnl": "447.6688",
"takerPnl": "-447.6688",
"makerPositions": [
{
"name": "IB_001",
"position": "-2028",
"vwap": "47.41",
"pnl": "447.6688"
}
],
"takerPositions": [
{
"name": "MT5_1",
"position": "2028",
"vwap": "47.41",
"pnl": "-447.6688"
}
]
},
{
"symbol": "A",
"exposure": "0",
"makerExposure": "-10",
"takerExposure": "10",
"makerPnl": "-4.6",
"takerPnl": "4.6",
"makerPositions": [
{
"name": "IB_002",
"position": "-10",
"vwap": "136.78",
"pnl": "-4.6"
}
],
"takerPositions": [
{
"name": "MT5_1",
"position": "10",
"vwap": "136.78",
"pnl": "4.6"
}
],
"total": 2
}
}
And my goal is to serialize it into a List of object from the NODE "Data":
I have the classes that map the data node fields:
public class Positions
{
public string name { get; set; }
public string position { get; set; }
public string vwap { get; set; }
public string pnl { get; set; }
}
public class ExPositions
{
public string symbol { get; set; }
public string exposure { get; set; }
public string makerExposure { get; set; }
public string takerExposure { get; set; }
public string makerPnl { get; set; }
public string takerPnl { get; set; }
public OZPositions makerPositions { get; set; }
public OZPositions takerPositions { get; set; }
}
Do you have any ideas how I can convert the node "data" to list of "ExPositions" objects, eg. List
I've did this but so far it throws an error
var positions = JsonSerializer.Deserialize<ExPositions>(json_string);

There is an error in your json - it's missing a closing ] for the array (I'll assume it's a typo).
The real problem is that you need a wrapper class to represent the data node of the json which should contain a list (or array) of ExPositions. The makerPositions and takerPositions should also become lists (or arrays) too. Add the following class and update the position properties of ExPositions:
public class Data
{
public List<ExPositions> data { get; set; }
}
// change positions to use a List too
public class ExPositions
{
...
public List<Positions> makerPositions { get; set; }
public List<Positions> takerPositions { get; set; }
}
Then you can deserialize using:
var result = JsonSerializer.Deserialize<Data>(json);
It's not clear where the ""total"": 2 property should be in your models (it's not clear in the json because of the issue I mentioned), you could add it to the Data class above (if it belongs there).
Online demo

Try with:
public class Positions
{
public string name { get; set; }
public string position { get; set; }
public string vwap { get; set; }
public string pnl { get; set; }
}
public class ExPositions
{
public string symbol { get; set; }
public string exposure { get; set; }
public string makerExposure { get; set; }
public string takerExposure { get; set; }
public string makerPnl { get; set; }
public string takerPnl { get; set; }
public Positions makerPositions { get; set; }
public Positions takerPositions { get; set; }
}
public class YourResult{
public ExPositions data { get; set; }
public int total { get; set; }
}
And then call:
var positions = JsonSerializer.Deserialize<YourResult>(json_string);

As haldo mentioned, there is a typo in your JSON. To quickly parse and validate your JSON data, you can use any online JSON parsers to validate your JSON data. I usually use the chrome extension JSON Viewer Pro.
Also, in the link that haldo provided to the .NET Fiddle for the demo, there is a trailing comma in JSON data which JSON deserializers might not ignore.
Here is the link to the edited demo that haldo provided.

Deserialize JSON using specific properties

I'm trying to deserialize JSON without declaring every property in C#. Here is a cut-down extract of the JSON:
{
"resourceType": "export",
"type": "search",
"total": 50,
"timestamp": "2020-08-02T18:26:06.747+00:00",
"entry": [
{
"url": "test.com/123",
"resource": {
"resourceType": "Slot",
"id": [
"123"
],
"schedule": {
"reference": {
"value": "testvalue"
}
},
"status": "free",
"start": "2020-08-03T08:30+01:00",
"end": "2020-08-03T09:00+01:00"
}
}
]
}
I want to get the values out of entry → resource, id and start.
Any suggestions on the best way to do this?

I've made very good experiences with json2sharp. You can enter your JSON data there and it will generate the classes you need to deserialize the JSON data for you.
public class Reference
{
public string value { get; set; }
}
public class Schedule
{
public Reference reference { get; set; }
}
public class Resource
{
public string resourceType { get; set; }
public List<string> id { get; set; }
public Schedule schedule { get; set; }
public string status { get; set; }
public string start { get; set; }
public string end { get; set; }
}
public class Entry
{
public string url { get; set; }
public Resource resource { get; set; }
}
public class Root
{
public string resourceType { get; set; }
public string type { get; set; }
public int total { get; set; }
public DateTime timestamp { get; set; }
public List<Entry> entry { get; set; }
}
The next step is to choose a framework which will help you to deserialize. Something like Newtonsoft JSON.
Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);

If you want to get the data without declaring classes, you can use Json.Net's LINQ-to-JSON API (JToken, JObject, etc.). You can use the SelectToken method with a JsonPath expression to get what you are looking for in a couple of lines. Note that .. is the recursive descent operator.
JObject obj = JObject.Parse(json);
List<string> ids = obj.SelectToken("..resource.id").ToObject<List<string>>();
DateTimeOffset start = obj.SelectToken("..resource.start").ToObject<DateTimeOffset>();
Working demo here: https://dotnetfiddle.net/jhBzl4
If it turns out there are actually multiple entries and you want to get the id and start values for all of them, you can use a query like this:
JObject obj = JObject.Parse(json);
var items = obj["entry"]
.Children<JObject>()
.Select(o => new
{
ids = o.SelectToken("resource.id").ToObject<List<string>>(),
start = o.SelectToken("resource.start").ToObject<DateTimeOffset>()
})
.ToList();
Demo: https://dotnetfiddle.net/Qe8NB7

I am not sure why you don't deserialize the lot (even if it's minimally populated) since you have to do the inner classes anyway.
Here is how you could bypass some of the classes (1) by digging into the JObjects
Given
public class Reference
{
public string value { get; set; }
}
public class Schedule
{
public Reference reference { get; set; }
}
public class Resource
{
public string resourceType { get; set; }
public List<string> id { get; set; }
public Schedule schedule { get; set; }
public string status { get; set; }
public string start { get; set; }
public string end { get; set; }
}
public class Entry
{
public string url { get; set; }
public Resource resource { get; set; }
}
You could call
var results = JObject.Parse(input)["entry"]
.Select(x => x.ToObject<Entry>());

How to deserialize multidimensional JSON

I know people asked and already got some answers very similar question before like this, but still, I couldn't figure it out about mine. I have a JSON file contains a multidimensional object, like below:
{
"Common": {
"Required": "Required Entry ",
"Photos": "Photos",
"Videos": "Videos",
"Register": "Register"
},
"Forms": {
"Form": "Forms",
"Name": "Name",
"Phone": "Phone",
"Email": "Email",
"Message": "Message"
},
"Sections": {
"Home": {
"EventDateTime": "",
"MainTitle": "",
"SubTitle": ""
},
"About": {},
"Venue": {},
"Schedule": {},
"Speakers": {},
"Sponsors": {},
"Price": {},
"Contact": {}
}
}
I would like to deserialize it into my view model (LanguagesViewModel) like this:
[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
public class LanguagesViewModel
{
public Common Common { get; set; }
public Buttons Buttons { get; set; }
public Forms Forms { get; set; }
public Navbar Navbar { get; set; }
public Sections Sections { get; set; }
}
public class Common
{
public string Required { get; set; }
public string Photos { get; set; }
public string Videos { get; set; }
public string Register { get; set; }
}
public class Forms
{
public string Form { get; set; }
public string Name { get; set; }
public string Phone { get; set; }
public string Email { get; set; }
public string Message { get; set; }
}
public class Sections
{
public Home Home { get; set; }
public About About { get; set; }
public Venue Venue { get; set; }
public Schedule Schedule { get; set; }
public Speakers Speakers { get; set; }
public Sponsors Sponsors { get; set; }
public Price Price { get; set; }
public Contact Contact { get; set; }
}
public class Home
{
public string EventDateTime { get; set; }
public string MainTitle { get; set; }
public string SubTitle { get; set; }
}
public class About
{
}
public class Venue
{
}
public class Schedule
{
}
public class Speakers
{
}
public class Sponsors
{
}
public class Price
{
}
public class Contact
{
}
}
Some of the snippet to do this:
using (StreamReader sr = new StreamReader(language_file_path))
{
string contents = sr.ReadToEnd();
items = JsonConvert.DeserializeObject<LanguagesViewModel>(contents);
}
Somehow, I only can get the first level of the objects, which is:
LanguagesViewModel{
Common:null,
Forms:null,
Sections:null
}
Not the second level, not the third level. Did I do something wrong or have I missed something? Very appreciated for any kind of help.
Thank you.

You can Use this static class
public static class JsonHelper
{
public static T ToObject<T>(this string content)
{
var obj = JObject.Parse(content).GetValue(typeof(T).Name);
if (obj == null)
throw new NullReferenceException();
else
return obj.ToObject<T>();
//This ToObject here is default method written in object
}
}
Usage
var mymodel= json.ToObject<Forms>();
Or create a JSON object and read it with magic strings.
//Creating your JSON object
JObject content = JObject.Parse(sr.ReadToEnd()//or your json);
//content["your object name"] let you access to you object
var common =(Common)content["Common"];
in multidimensional objects, you can access them like this.
//content["level1"]["level2"]["level3"] & ...
var sections= (Home)content["Sections"]["Home"];
Also this way may work but i prefer the way with magic strings.
dynamic jsonObject = new JObject.Parse(sr.ReadToEnd());
var common = jsonObject.Common;

I hope this Helps!

JSON invalid format

I'm trying to deserialize the JSON from the weather API, I have created C# classes but I can't seem to get it working. Most sites display this JSON as invalid format, so I'm not really sure whats wrong with it. Here is the JSON string and my class for Deserializing.Visual studio displays it like any other regular JSON.

Your JSON is not valid.
The main thing is that you are using brackets [] where you should be using braces {}.
In JSON [] is an array, while {} is an object. There are a couple of places where you need to have an array (e.g. list) so you can't simply do a find-replace to fix this.
An easy way to resolve this in the future is to create an instance of your WeatherInfo class, populate it with data, and then serialize it to JSON. You can then compare that with the JSON you have (using a diff tool like KDiff or WinMerge) to identify where your source JSON is different from your generated JSON.

A valid JSON always starts with a [ or a { and ends with the same, where square bracket [ represents an array and curly bracket { represents an object.
Looking at your C# class, your JSON lacks the curly brace to start with for objects and is also missing names for the arrays like allinfos.
You should start building your JSON like this:
var json = JToken.Parse
("{\"cod\":\"200\",\"message\":0,\"cnt\":40,\"list\":{\"allinfos\":[{\"dt\":1574175600, \"main\":{\"temp\":284.79,\"temp_min\":282.63,\"temp_max\":284.79,\"pressure\":1021,\"sea_level\":1021,\"grnd_level\":958,\"humidity\":88,\"temp_kf\":2.16}}]}}").ToString(Formatting.Indented);
This will give a formatted, easy to read output like this:
{
"cod": "200",
"message": 0,
"cnt": 40,
"list": {
"allinfos": [
{
"dt": 1574175600,
"main": {
"temp": 284.79,
"temp_min": 282.63,
"temp_max": 284.79,
"pressure": 1021,
"sea_level": 1021,
"grnd_level": 958,
"humidity": 88,
"temp_kf": 2.16
}
}
]
}
}

Update: The JSON was actually valid, the problem is that I was trying to work with debugging version of the string. The debugger automatically adds escape characters and "" quotes. Also some of the classes I had didn't follow up the JSON format correctly, so that error stopped me from seeing the real issue here.

Parse JSON object in C#

I use JSON.NET and I would like to parse the following object which I get from a WebService. Can someone post an example on how to do that?
#"{""MessageType"":0,
""Message"":""Success"",
""Value"":[
{""listId"":1,
""listName"":""DemoList"",
""itemInList"":[
{
""fromDate"":""\/Date(1228946400000)\/"",
""fromLocation"":null,
""toLocation"":null,
""originalRequest"":""water"",
""creationDate"":""\/Date(1339448400000)\/"",
""typeId"":1
},
{
""fromDate"":null,
""fromLocation"":null,
""toLocation"":null,
""originalRequest"":""gala"",
""creationDate"":""\/Date(1304370000000)\/"",
""typeId"":1
}
]}
]}"
JSON Object
{
"MessageType":0,
"Message":"UserLists",
"Value":
[
{
"listId":1,
"listName":"DemoList",
"itemInList"
[
{
"fromDate":"\/Date(1228946400000)\/",
"fromLocation":null,
"toLocation":null,
"originalRequest":"water",
"creationDate":"\/Date(1339448400000)\/",
"typeId":1
},
{
"fromDate":null,
"fromLocation":null,
"toLocation":null,
"originalRequest":"gala",
"creationDate":"\/Date(1304370000000)\/",
"typeId":1
}
],
"numberOfItems":2
}
]
}
Thanks.

You need to create some entity like this:
public class Entity
{
public int MessageType { get; set; }
public string Message { get; set; }
public List<EntityValue> Value { get; set; }
}
public class EntityValue
{
public int listId { get; set; }
public string listName { get; set; }
public List<ItemInList> itemInList { get; set; }
}
public class ItemInList
{
public DateTime? fromDate { get; set; }
public string fromLocation { get; set; }
public string toLocation { get; set; }
public string originalRequest { get; set; }
public DateTime creationDate { get; set; }
public int typeId { get; set; }
}
The entity must has the same structure like the json data.
And you can call the Method:
JsonConvert.DeserializeObject<Entity>(json);
If it has any exception,you need to adjust the entities until it works.
