Say I have a Json as below:
{
"Records123": {
"-count": "1",
"-count2": "2",
"-count3": "4",
"Metadata": {
"value": 2,
"sum": 5
}
}
}
How do I get only the root name i.e 'Records123' in this case for Json (using Json.net or any method) , the way we have XDocument.Root.Name.LocalName in XML...
How to get the Root attributes i.e 'count' in this case like we have XDocument.Root.Attributes() in XML?
You could use JObject like this
var jsonObject = JObject.Parse(jsonString);
foreach (var tmp in jsonObject)
{
Console.WriteLine(tmp.Key);
}
For your sample JSON this should give you Records123 on the console. You have to add some logic here to get the first item only, which is a bit more tricky to JProperty handling.
Edit
For getting the other properties use
var jsonObject = JObject.Parse(jsonString);
foreach(JObject jsonProperty in jsonObject.Children<JProperty>().First())
{
foreach (var property in jsonProperty.Properties())
{
Console.WriteLine(property.Name);
}
}

I have a .NET Core 3.1 C# application reading the following JSON doc:
{
"info": {
"_postman_id": "b"
},
"item": [
{
"name": "GetEntityById via APIM",
"item": [
{
"name": "Call 1",
"url": {
"raw": "urlforcall1"
}
},
{
"name": "Call 2",
"url": {
"raw": "urlforcall2"
}
}
]
}
]
}
I want to select the value for each item\item\name and each item\item\url\raw.
So, I'd like to end up with "Call 1":"urlforcall1" and "Call 2":"urlforcall2".
I've been playing around and can grab the value from the raw token with the following:
var jObject = JObject.Parse(jsonString);
var urls = jObject.SelectTokens("..raw");
How can I grab the value from its parent's sibling, name?
I hope this code will help you
using Newtonsoft.Json.Linq;
using System;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
string json = #"
{
'info': {
'_postman_id': 'b'
},
'item': [
{
'name': 'GetEntityById via APIM',
'item': [
{
'name': 'Call 1',
'url': {
'raw': 'urlforcall1',
}
},
{
'name': 'Call 2',
'url': {
'raw': 'urlforcall2',
}
}
]
}
]
}";
dynamic d = JObject.Parse(json);
foreach(var item in d.item)
{
foreach(var innerItem in item.item)
{
Console.WriteLine($"'{innerItem.name}' : '{innerItem.url.raw}'");
}
}
}
}
}

To answer your question directly, if you have a JToken you can navigate upward from there using the Parent property. In your case you would need to use it four times to get to the level you want:
The parent of the JValue representing the call URL string is a JProperty with the name raw
The parent of that JProperty is a JObject
The parent of that JObject is a JProperty with the name url
The parent of that JProperty is a JObject, which also contains the name property
From there you can navigate back down using indexer syntax to get the value of name.
So, you would end up with this:
var jObject = JObject.Parse(jsonString);
foreach (JToken raw in jObject.SelectTokens("..raw"))
{
string callName = (string)raw.Parent.Parent.Parent.Parent["name"];
string urlForCall = (string)raw;
}
You may flatten inner item array using SelectMany method into one sequence (since outer item is also an array), then get name and raw values directly by key
var jObject = JObject.Parse(jsonString);
var innerItems = jObject["item"]?.SelectMany(t => t["item"]);
foreach (var item in innerItems)
{
var name = item["name"];
var raw = item["url"]?["raw"];
}
I can´t find a value in a json string using json.net
I´ve tried jsonstr[0].track_numbers[0].track_number
This is my json file.
{
"0": {
"increment_id": "112",
"track_numbers": [
{
"track_number": "2223",
"title": "tit",
"carrier_code": "custom"
}
]
},
"live_shipping_status": "Delivered"
}
I want to find the Track_nummber.
dynamic jsonstr = JsonConvert.DeserializeObject(json));
var track = jsonstr[0].track_numbers[0].track_number
(donsent work)
The 0 of your json is a string key, not an index position:
dynamic obj = JsonConvert.DeserializeObject(json);
var trackNumber = obj["0"].track_numbers[0].track_number;
Note the difference in getting the first entry of track_numbers, which is an array.
I have the following JObject as return by https://gate.io/api2#trade API. How do I iterate through each key which is a separate coin also get its value.
I tried to parse it using Newtonsoft JObject Parse like this:
var coinData = JObject.Parse(#"{
""result"": ""true"",
""available"": {
""BTC"": ""0.83337671"",
""LTC"": ""94.364"",
""ETH"": ""0.07161"",
""ETC"": ""82.35029899""
},
""locked"": {
""BTC"": ""0.0002"",
""YAC"": ""10.01""
}
}")["available"];
foreach (JToken item in coinData)
{
item.Key
}
but then JToken doesn't give access to key values. I don't know how to further parse it.
JSON received from gateio api:
{
"result": "true",
"available": {
"BTC": "0.83337671",
"LTC": "94.364",
"ETH": "0.07161",
"ETC": "82.35029899"
},
"locked": {
"BTC": "0.0002",
"YAC": "10.01"
}
}
EDIT: Should I break it with ':' while iterating in loop? This is working if i break it and replace quotes.
foreach (JToken item in coinData)
{
var data = item.ToString().Replace("\"", String.Empty).Split(':');
}
var data has two parts, 1 => coin name, 2 => balance.
Is there any other legit way?
JToken is base class for all types of json tokens. In your case though you want only json properties, so you need to filter by more narrow type - JProperty. You can filter to include only property tokens like this:
foreach (var item in coinData.OfType<JProperty>()) {
string coinName = item.Name;
// to parse as decimal
decimal balance = item.Value.Value<decimal>();
// or as string
string balanceAsString = item.Value.Value<string>();
}
I would suggest being very explicit about expecting the result of "available" to be another object, by casting to JObject. You can then call Properties() to get its properties, each as a JProperty. Here's a complete example to demonstrate:
using System;
using Newtonsoft.Json.Linq;
class Program
{
public static void Main()
{
string json = #"{
'result': 'true',
'available': {
'BTC': '0.83337671',
'LTC': '94.364',
'ETH': '0.07161',
'ETC': '82.35029899'
},
'locked': {
'BTC': '0.0002',
'YAC': '10.01'
}
}".Replace('\'', '"');
JObject root = JObject.Parse(json);
JObject coins = (JObject) root["available"];
foreach (JProperty property in coins.Properties())
{
string name = property.Name;
string value = (string) property.Value;
Console.WriteLine($"Name: {name}; Value: {value}");
}
}
}
I have a JSON file I'm reading from text and parsing it into JObject using Newtonsoft.Json.Linq. The JSON file looks like this:
{
"EntityTypeDto":[
{
"EntityType":"Grade",
"Language":"ES"
},
{
"EntityType":"ApplicationType",
"Language":"ES"
},
{
"EntityType":"Borough",
"Language":"ES"
}
]
}
Using the Newtonsoft library, are there any methods I can leverage on JObject to replace the Language property of all the objects to another value? If not what would be another way to do this? This project is a console application in C#, VS 2012, thanks.
You don't need Linq here to achieve what you need , Linq is for consult data, not for modify it. So you can just, eg, a foreach to iterate and modify the elements of the array:
JObject json= JObject.Parse(jsonString);
JArray entityTypeDtos= (JArray)json["EntityTypeDto"];
foreach(var e in entityTypeDtos)
{
if(e["Language"] != null)
e["Language"]="EN";
}
I'm guessing by the Linq tag you would like a Linq approach try this
string json = #"{
'EntityTypeDto':[
{
'EntityType':'Grade',
'Language':'ES'
},
{
'EntityType':'ApplicationType',
'Language':'ES'
},
{
'EntityType':'Borough',
'Language':'ES'
}
]
}";
JObject myjobj = JObject.Parse(json);
JArray EntityType = (JArray)myjobj["EntityTypeDto"];
(from eobj in EntityType
where eobj["Language"]="ES"
select eobj).ForEach(x => x["Language"]="New Value");
I have a JSON string from which I want to be able to delete some data.
Below is the JSON response:
{
"ResponseType": "VirtualBill",
"Response": {
"BillHeader": {
"BillId": "7134",
"DocumentId": "MN003_0522060",
"ConversionValue": "1.0000",
"BillType": "Vndr-Actual",
"AccountDescription": "0522060MMMDDYY",
"AccountLastChangeDate": "06/07/2016"
}
},
"Error": null
}
From above JSON response I want to able remove the
"ResponseType": "VirtualBill", part such that it looks like this:
{
"Response": {
"BillHeader": {
"BillId": "7134",
"DocumentId": "MN003_0522060",
"ConversionValue": "1.0000",
"BillType": "Vndr-Actual",
"AccountDescription": "0522060MMMDDYY",
"AccountLastChangeDate": "06/07/2016"
}
},
"Error": null
}
Is there an easy way to do this in C#?
Using Json.Net, you can remove the unwanted property like this:
JObject jo = JObject.Parse(json);
jo.Property("ResponseType").Remove();
json = jo.ToString();
Fiddle: https://dotnetfiddle.net/BgMQAE
If the property you want to remove is nested inside another object, then you just need to navigate to that object using SelectToken and then Remove the unwanted property from there.
For example, let's say that you wanted to remove the ConversionValue property, which is nested inside BillHeader, which is itself nested inside Response. You can do it like this:
JObject jo = JObject.Parse(json);
JObject header = (JObject)jo.SelectToken("Response.BillHeader");
header.Property("ConversionValue").Remove();
json = jo.ToString();
Fiddle: https://dotnetfiddle.net/hTlbrt
Convert it to a JsonObject, remove the key, and convert it back to string.
Sample sample= new Sample();
var properties=sample.GetType().GetProperties().Where(x=>x.Name!="ResponseType");
var response = new Dictionary<string,object>() ;
foreach(var prop in properties)
{
var propname = prop.Name;
response[propname] = prop.GetValue(sample); ;
}
var response= Newtonsoft.Json.JsonConvert.SerializeObject(response);
