I need to manipulate the following JSON Array to compare the value for Company Id. Any suggestions how I can manipulate this.
{ "39513447": { "field": "39513447", "label": "CompanyId", "type": "number", "value": "5907" }, "39513458": { "field": "39513458", "label": "UserId", "type": "number", "value": "5904" }, "39380671": { "field": "39380671", "label": "Name", "type": "name", "value": "first = First\nlast = Name" }, "39380675": { "field": "39380675", "label": "Company Name", "type": "text", "value": "CompanyName" }, "39381333": { "field": "39381333", "label": "Planned Gross Salary Amount", "type": "number", "value": "11020" }, "39381266": { "field": "39381266", "label": "Per:", "type": "select", "value": "Annum" }, "39380485": { "field": "39380485", "label": "Planned Gross Dividend Amount", "type": "number", "value": "31980" }, "39381357": { "field": "39381357", "label": "Per:", "type": "select", "value": "Annum" }}
I have a class with these 3 properties:
public int id { get; set; }
public DateTime timestamp { get; set; }
public object data { get; set; }
Which I deserialize using:
T jsonObject = JsonConvert.DeserializeObject<T>(text);
Ideally want to deserialize into class with these 4 properties:
public string field { get; set; }
public string label { get; set; }
public string type { get; set; }
public string value { get; set; }
Create a class:
public class MyClass
{
public string field { get; set; }
public string label { get; set; }
public string type { get; set; }
public string value { get; set; }
}
And simple deserialize your json into a Dictionary:
var json = GetJsonString();
var dict = JsonConvert.DeserializeObject<Dictionary<int,MyClass>>(json);
Here's how to fetch data:
var curr = dict[39513447];
var field = curr.field;
var label = curr.label;
// etc.

I am having trouble deserializing JSON received from HubSpot ContactList API.
I am using Restsharp and NewtonSoft, and I'm having real struggles understanding how to correctly define the required classes in order to deserialize the JSON string, which is below:
"contacts": [

}
],
"merge-audits": []
}
],
"has-more": false,
"vid-offset": 2401
}
If I simply request the vid, I correctly get 2 vid's back. It's when I try to do the properties and that i get a fail.
Please help
Lets reduce the Json to the minimum to reproduce your error :
{
"vid": 2301,
"portal-id": 5532227,
"is-contact": true,
"profile-url": "https://app.hubspot.com/contacts/5532227/contact/2301",
"properties": {
"firstname": {
"value": "Carlos"
},
"lastmodifieddate": {
"value": "1554886333954"
},
"company": {
"value": "Khaos Control"
},
"lastname": {
"value": "Swannington"
}
}
}
And the appropriate class ContactListAPI_Result:
public partial class ContactListAPI_Result
{
[JsonProperty("vid")]
public long Vid { get; set; }
[JsonProperty("portal-id")]
public long PortalId { get; set; }
[JsonProperty("is-contact")]
public bool IsContact { get; set; }
[JsonProperty("profile-url")]
public Uri ProfileUrl { get; set; }
[JsonProperty("properties")]
public Dictionary<string, Dictionary<string, string>> Properties { get; set; }
}
public partial class ContactListAPI_Result
{
public static ContactListAPI_Result FromJson(string json)
=> JsonConvert.DeserializeObject<ContactListAPI_Result>(json);
//public static ContactListAPI_Result FromJson(string json)
// => JsonConvert.DeserializeObject<ContactListAPI_Result>(json, Converter.Settings);
}
public static void toto()
{
string input = #" {
""vid"": 2301,
""portal-id"": 5532227,
""is-contact"": true,
""profile-url"": ""https://app.hubspot.com/contacts/5532227/contact/2301"",
""properties"": {
""firstname"": {
""value"": ""Carlos""
},
""lastmodifieddate"": {
""value"": ""1554886333954""
},
""company"": {
""value"": ""Khaos Control""
},
""lastname"": {
""value"": ""Swannington""
}
}
}";
var foo = ContactListAPI_Result.FromJson(input);
}
But the Value of one property will be burrow in the sub dictionary, we can the project the object in a more usefull one :
public partial class ItemDTO
{
public long Vid { get; set; }
public long PortalId { get; set; }
public bool IsContact { get; set; }
public Uri ProfileUrl { get; set; }
public Dictionary<string, string> Properties { get; set; }
}
Adding the projection to the Class:
public ItemDTO ToDTO()
{
return new ItemDTO
{
Vid = Vid,
PortalId = PortalId,
IsContact = IsContact,
ProfileUrl = ProfileUrl,
Properties =
Properties.ToDictionary(
p => p.Key,
p => p.Value["value"]
)
};
}
Usage :
var result = foo.ToDTO();
Live Demo
Creating and managing class structure for big and nested key/value pair json is tedious task
So one approach is to use JToken instead.
You can simply parse your JSON to JToken and by querying parsed object, you will easily read the data that you want without creating class structure for your json
From your post it seems you need to retrieve vid and properties from your json so try below code,
string json = "Your json here";
JToken jToken = JToken.Parse(json);
var result = jToken["contacts"].ToObject<JArray>()
.Select(x => new
{
vid = Convert.ToInt32(x["vid"]),
properties = x["properties"].ToObject<Dictionary<string, JToken>>()
.Select(y => new
{
Key = y.Key,
Value = y.Value["value"].ToString()
}).ToList()
}).ToList();
//-----------Print the result to console------------
foreach (var item in result)
{
Console.WriteLine(item.vid);
foreach (var prop in item.properties)
{
Console.WriteLine(prop.Key + " - " + prop.Value);
}
Console.WriteLine();
}
Output:
OK. I have sent a GET request to SharePoint and received a string back:

What I ultimately want to do is create a dropdown that is populated with the SerialNumber. When the SerialNumber is selected in the dropdown, it will return the id so that I can then plug that into a GET request to retrieve the appropriate listitems.
I am trying to figure out if I need to do a foreach to create a LIST<> or something else all together.
I do have this class setup, but wasn't sure if I could use it the way I thought I could.
public class Lookup
{
string id { get; set; };
string SerialNumber { get; set; }
}
This is the final working code:
private async void GetButton_Click(object sender, RoutedEventArgs e)
{
var (authResult, message) = await Authentication.AquireTokenAsync();
ResultText.Text = message;
if (authResult != null)
{
var httpClient = new HttpClient();
HttpResponseMessage response;
var request = new HttpRequestMessage(HttpMethod.Get, geturl);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", authResult.AccessToken);
response = await httpClient.SendAsync(request);

There are two way can create model easily.
You can use Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class, you can easier to know the relation between Json and model.
If you can't use Web Essentials you can instead of use http://json2csharp.com/ online JSON to Model class.
You can try to use those models to carry your JSON Format.
public class Lookup
{
public string SerialNumber { get; set; }
public string id { get; set; }
}
public class Value
{
public Lookup fields { get; set; }
}
public class RootObject
{
public List<Value> value { get; set; }
}
Then you can use obj.value property collection directly.
var obj = JsonConvert.DeserializeObject<RootObject>(jsonData);
foreach (var item in obj.value)
{
//item.fields.id
//item.fields.SerialNumber
}
A good example of how to bind a list of data to Combobox ( dropdown ) is here : https://www.c-sharpcorner.com/article/data-binding-in-xaml-uwp-using-combobox/
in this example the class is a Student with id and Name and it shows how u can show the name in combobox.
I will modify it a little for your scenario but if you want to go in depth than you can visit the provided link above.
This is the class
public class Fields
{
public string SerialNumber { get; set; }
public string id { get; set; }
public override string ToString()
{
return this.SerialNumber; // so that we can just bind to the object and get serial number in the ui.
}
}
Backend for adding items to the List
public sealed partial class MainPage: Page
{
List<Lookup> Lookups = new List<Lookup>();
public MainPage()
{
this.InitializeComponent();
Lookups.Add(new Lookup() {id = 1, SerialNumber = "S1"});
Lookups.Add(new Lookup() {id = 2, SerialNumber = "S2"});
Lookups.Add(new Lookup() {id = 3, SerialNumber = "S3"});
Lookups.Add(new Lookup() {id = 4, SerialNumber = "S4"});
//add as many items here as u want, u can even use a for loop or foreach loop or a Deserializer with newsoft json to get objects from ur json like below.
//var data = JsonConvert.DeserializeObject<RootObject>(jsonData);
//foreach (var d in data.value)
//{
// //d.fields.id //this is how u can get the inside properties.
//}
yourComboBox.ItemSource = Lookups;//setting item source to UI.
}
}
after you successfully bind the data with UI you can use SelectionChanged event of your combobox to do further logic as you require,
void MyComboBox_SelectionChanged(object sender, object args)
{
if(MyCombobox.SelectedIndex!=-1)
{
var mylookupId = (MyCombobox.SelectedItem as Lookup).id;// get your id and do further processing here.
}
}
I think this will be easy when using newtonsoft:
var dynamicObject = JObject.Parse(yourstring);
var list = new List<Lookup>();
//now you have a dynamic object containing an array.
//this should be doable with linq as well.
//note, the type is dynamic
foreach (dynamic thing in dynamicObject )
{
list.Add(new Lookup()
{
id = thing.fields.id,
SerialNumber = thing.fields.SerialNumber
});
}
disclaimer: not tested in any way ;-)
"fields": [
{
"field": {
"name": "SMS",
"value": "Yes"
}
},
{
"field": {
"name": "Email",
"value": ""
}
},
{
"field": {
"name": "Total",
"value": ""
}
},
]
I have tried to form the JSON format like above, so i formed the class like below. While serialization it does not return expected form, how can i achieve this one.
public class Test
{
public List<Field> fields;
}
public class Field
{
public string name { get; set; }
public string value { get; set; }
}
Response:
"fields": [{
"name": "SMS",
"value": "Yes"
}, {
"name": "Email",
"value": ""
},{
"name": "Total",
"value": ""
}]
Use this website http://json2csharp.com and generate all the classes automatically. Just copy-paste your json there.
You can customize resulting JSON object with anonymous types and LINQ. Please try this code:
var test = new Test {fields = new List<Field>()};
test.fields.Add(new Field {name = "f1", value = "v1"});
test.fields.Add(new Field {name = "f2", value = "v2"});
var json = JObject.FromObject(new { fields = test.fields.Select(f => new {field = f}).ToArray() })
.ToString();
A json variable would be:
{
"fields": [
{
"field": {
"name": "f1",
"value": "v1"
}
},
{
"field": {
"name": "f2",
"value": "v2"
}
}
]
}
You just missed a class level:
public class Test
{
public List<FieldHolder> fields;
}
public class FieldHolder
{
public Field field { get; set; }
}
public class Field
{
public string name { get; set; }
public string value { get; set; }
}
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();
}
I'm trying to deserialize a json string and I'm getting the error End element 'caption' from namespace '' expected. Found element 'created_time' from namespace ''. when calling
InstagramObject test = (InstagramObject) instagramObject.ReadObject(instagramWebResponse.GetResponseStream());
The json from Instagram returns many elements but there are only a few that I need. My DataContract will be posted below.
Basically I need {data:[{caption: string, link: string, images: {...}}]}
Here's an example of the json...
{
"data": [{
"comments": {
"data": [],
"count": 0
},
"caption": {
"created_time": "1296710352",
"text": "Inside le truc #foodtruck",
"from": {
"username": "kevin",
"full_name": "Kevin Systrom",
"type": "user",
"id": "3"
},
"id": "26621408"
},
"likes": {
"count": 15,
"data": [{
"username": "mikeyk",
"full_name": "Mike Krieger",
"id": "4",
"profile_picture": "..."
}, {...subset of likers...}]
},
"link": "http://instagr.am/p/BWrVZ/",
"user": {
"username": "kevin",
"profile_picture": "http://distillery.s3.amazonaws.com/profiles/profile_3_75sq_1295574122.jpg",
"id": "3"
},
"created_time": "1296710327",
"images": {
"low_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_6.jpg",
"width": 306,
"height": 306
},
"thumbnail": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_5.jpg",
"width": 150,
"height": 150
},
"standard_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_7.jpg",
"width": 612,
"height": 612
}
},
"type": "image",
"filter": "Earlybird",
"tags": ["foodtruck"],
"id": "22721881",
"location": {
"latitude": 37.778720183610183,
"longitude": -122.3962783813477,
"id": "520640",
"street_address": "",
"name": "Le Truc"
}
}]
}
and here's my DataContract...
[DataContract]
public class InstagramObject {
[DataMember(Name = "data")]
public IEnumerable<InstagramData> instagramData { get; set; }
}
[DataContract]
public class InstagramData {
[DataMember(Name = "images")]
public List<InstagramImage> instagramImages { get; set; }
[DataMember(Name = "caption")]
public string caption { get; set; }
[DataMember(Name = "link")]
public string link { get; set; }
}
[DataContract]
public class InstagramImage {
[DataMember(Name = "low_resolution")]
public InstagramImageInfo lowResolutionImage { get; set; }
[DataMember(Name = "thumbnail")]
public InstagramImageInfo thumbnail { get; set; }
[DataMember(Name = "standard_resolution")]
public InstagramImageInfo standardResolution { get; set; }
}
[DataContract]
public class InstagramImageInfo {
[DataMember(Name = "url")]
public string url { get; set; }
[DataMember(Name = "width")]
public int width { get; set; }
[DataMember(Name = "height")]
public int height { get; set; }
}
In the data contract caption is declared as a string, but in the JSON caption is a record with various fields - caption should be declared to be an object with a compatible structure:
[DataContract]
public class InstagramCaption {
[DataMember(Name = "text")]
public string Text {get; set;}
}
. . .
[DataMember(Name = "caption")]
public InstagramCaption caption { get; set; }
. . .
No need to declare those clases If you want to go with Json.Net + Linq
var obj = (JObject)JsonConvert.DeserializeObject(json);
var result = obj["data"]
.Select(x => new {
Caption = (string)x["caption"]["text"],
Link = (string)x["link"],
Images = x["images"].Children()
.Select(y=>(string)y.First()["url"]).ToArray()
})
.ToArray();
