I am working with an API that uses GraphQL and returns JSON data and I want to deserialize the JSON content dynamically rather than map the entire service structure in my application into C# data structures (.NET types/classes).
I've done this before but the JSON data was quite simple and straightforward. However, the this API I'm working with returns more complex/verbose JSON and I'm struggling to parse it properly.
Can anyone advise on how to parse the below JSON? That is, how to access the dynamic JSON's objects/properties.
I'm using Newtonsoft.Json. This is my code to deserialize:
byte bC = 0;
string location_text = string.Empty;
string location_value = string.Empty;
dynamic results = JsonConvert.DeserializeObject<dynamic>(json);
foreach (dynamic d in results)
{
bC = d.data.locationSuggestions.Count; // d.locationSuggestions.Count
for (byte b = 0; b < bC; b++)
{
location_text = d.data.locationSuggestions[b].location.contextualName;
location_value = d.data.locationSuggestions[b].location.id.value;
}
}
When I run this code I get an error that says "data" or "locationSuggestions" cannot be found.
The JSON I'm trying to parse is as follows:
{
"data": {
"locationSuggestions": [
{
"location": {
"id": {
"value": "seekAnzPublicTest:location:seek:2dkY4vZJF"
},
"name": "Brisbane",
"contextualName": "Brisbane QLD 4000 AU",
"countryCode": "AU",
"parent": {
"id": {
"value": "seekAnzPublicTest:location:seek:2FjxhQans"
},
"name": "CBD & Inner Suburbs",
"parent": {
"id": {
"value": "seekAnzPublicTest:location:seek:32XZdsa2K"
},
"name": "Brisbane"
}
}
}
},
{
"location": {
"id": {
"value": "seekAnzPublicTest:location:seek:2ckmimaF1"
},
"name": "Brisbane Grove",
"contextualName": "Brisbane Grove NSW 2580 AU",
"countryCode": "AU",
"parent": {
"id": {
"value": "seekAnzPublicTest:location:seek:2UC23LszP"
},
"name": "Southern Highlands & Tablelands",
"parent": {
"id": {
"value": "seekAnzPublicTest:location:seek:FTwZdE2K"
},
"name": "New South Wales"
}
}
}
}
]
},
"extensions": {
"requestLatency": 171
}
}
Regarding your JSON string, you can use dynamic to parse it and access the data as shown below:
You can also find a working example at: https://dotnetfiddle.net/lnhwJz
using System;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
var jsonString=#"{'data':{'locationSuggestions':[{'location':{'id':{'value':'seekAnzPublicTest:location:seek:2dkY4vZJF'},'name':'Brisbane','contextualName':'Brisbane QLD 4000 AU','countryCode':'AU','parent':{'id':{'value':'seekAnzPublicTest:location:seek:2FjxhQans'},'name':'CBD & Inner Suburbs','parent':{'id':{'value':'seekAnzPublicTest:location:seek:32XZdsa2K'},'name':'Brisbane'}}}},{'location':{'id':{'value':'seekAnzPublicTest:location:seek:2ckmimaF1'},'name':'Brisbane Grove','contextualName':'Brisbane Grove NSW 2580 AU','countryCode':'AU','parent':{'id':{'value':'seekAnzPublicTest:location:seek:2UC23LszP'},'name':'Southern Highlands & Tablelands','parent':{'id':{'value':'seekAnzPublicTest:location:seek:FTwZdE2K'},'name':'New South Wales'}}}}]},'extensions':{'requestLatency':171}}";
var parsedData=JsonConvert.DeserializeObject<dynamic>(jsonString);
foreach(var item in parsedData.data.locationSuggestions)
{
Console.WriteLine(item.location.name);
Console.WriteLine(item.location.id.value);
Console.WriteLine(item.location.contextualName);
}
}
}
Output:
Brisbane
seekAnzPublicTest:location:seek:2dkY4vZJF
Brisbane QLD 4000 AU
Brisbane Grove
seekAnzPublicTest:location:seek:2ckmimaF1
Brisbane Grove NSW 2580 AU

Can you help me parse the values in 'realEstateProperties' attribute (ex. serial number and economyType.value). Here is a part of the json file:
{
"Entity1": {
"id": "5f514d20744a1fb",
"realEstateProperties": [
{
"serialNumber": "11",
"cadastralSections": [
{
"id": "5f514dc11a1e3",
"economyType": {
"value": "landRegisterPage.type",
}
}
],
"landRegisterPage": {
"id": "3456",
"landRegisterBook": {
"abbreviation": null
},
"note": "LRP",
"tags": null
},
"propertyTextBlock": null
}
],
"customFields": [],
Here is what I currently have:
public static string[] GetJsonValues(string jsonProperty)
{
testCaseName = "Entity1";
FixtureIncident.Root incObject = new FixtureIncident.Root();
incObject = LoadJSONFile();
JObject incJson = JObject.FromObject(incObject);
var attributes = incJson[testCaseName].ToList<JToken>();
var property = attributes.Find(i => i.ToObject<JProperty>().Name == jsonProperty) as JArray; //returns property=null
string[] Properties = property.ToObject<string[]>();
return Properties;
}
property returns null and I am not sure how to correct it.
I need to save all the realEstateProperties values in a string[].
I found some similar topics but I couldn't adjust my code so I make it works. Thanks in advance for your help.
How do i filter out to obtain the text ("I can provide....")? The program im using has no variable that contains just this text. Thanks!
{
"session_id": "9643039c-edf0-435a-8345-fc225859a6de"
}
{
"output": {
"generic": [
{
"response_type": "text",
"text": "I can provide you with directions, locations and operating hours as of now."
}
],
"intents": [
{
"intent": "Function",
"confidence": 0.30141472287041043
}
],
"entities": []
}
}
{}
Thanks...took me longer than it should have but here it the code:
string response = dialog.Message();
JObject data = JObject.Parse(response);
Console.WriteLine(data["output"]["generic"].First["text"]);
string text = data["output"]["generic"].First["text"].ToString();
I am fetching /me/apprequests from Facebook API. It works and I get the data in JSON format.
Thing is that everything is nested, like a dictionary inside a dictionary.
What i tried:
Dictionary<string, object> dict = Facebook.MiniJSON.Json.Deserialize(result.RawResult) as Dictionary<string, object>;
object data;
string request_code = "";
if (dict.TryGetValue("data", out data))
{
var rc = (((Dictionary<string, object>)data)["id"]);
request_code = (string)rc;
}
Debug.Log("request_code=" + request_code);
I think I need to loop the dictionary to get all id's.
I can confirm that if (dict.TryGetValue("data", out data)) does work correctly and get the dictionary of data arrays, but fails here (((Dictionary<string, object>)data)["id"]); with casting error.
Json looks like:
{
"data": [{
"application": {
"category": "Games",
"link": "https:\/\/www.facebook.com\/games\/?app_id=2523532533",
"name": "game name",

}
}
}
Managed to make it work if it will help someone:
string request_code = "";
if (dict.TryGetValue("data", out data))
{
int dataLength = ((List<object>)data).Count;
for (int i = 0; i < dataLength; i++)
{
var rc = ((List<object>)data)[i];
var rc2 = (((Dictionary<string, object>)rc)["id"]);
request_code = (string)rc2;
Debug.Log("request_code=" + request_code);
}
}
i am trying to get a value from a json file using c#. the json file looks more like the below string.

I am looking for the formatted_address element from the json from C#. I am getting lost in JObject, JArray, JToken. I am trying to use NewtonSoft JSON. Thank you.
Using the LINQ-to-JSON API (JObjects) you can get the formatted address easily using the SelectToken method:
JObject obj = JObject.Parse(json);
string address = (string)obj.SelectToken("results[0].formatted_address");
Console.WriteLine(address);
Fiddle: https://dotnetfiddle.net/Fdvqkl
The easiest way would be to have model objects and then call
var rootObject = JsonConvert.DeserializeObject(jsonString);
With jsonString being your input. Then you can retrieve the formatted_address from the first array element like this like this:
var formattedAddress = rootObject.results[0].formatted_address;
Hope it helps.
using Newtonsoft.Json nuget . and do something like that
static void Main(string[] args)
{
string json = "{'results':[{'SwiftCode':'','City':'','BankName':'Deutsche Bank','Bankkey':'10020030','Bankcountry':'DE'},{'SwiftCode':'','City':'10891 Berlin','BankName':'Commerzbank Berlin (West)','Bankkey':'10040000','Bankcountry':'DE'}]}";
var resultObjects = AllChildren(JObject.Parse(json))
.First(c => c.Type == JTokenType.Array && c.Path.Contains("results"))
.Children<JObject>();
foreach (JObject result in resultObjects)
{
foreach (JProperty property in result.Properties())
{
// do something with the property belonging to result
}
}
}
// recursively yield all children of json
private static IEnumerable<JToken> AllChildren(JToken json)
{
foreach (var c in json.Children())
{
yield return c;
foreach (var cc in AllChildren(c))
{
yield return cc;
}
}
}
change JTokenType.Array to whatever the type u wish , also change the "results" to the property name you wish to extract
this is my json file

i want to get this "id": "4c190e01" from json
dynamic value = Newtonsoft.Json.JsonConvert.DeserializeObject(result);
string id = Convert.ToString(value.id[0]);
this is my code but i am not getting 4c190e01 id
rewrite your code as following...
dynamic valuePoco = Newtonsoft.Json.JsonConvert.DeserializeObject(result);
string id = Convert.ToString(valuePoco.createdBy.application.id);
You can use the path to the desired property. If you want to select the element with 4c190e01 as id, you can use
string id = value.createdBy.application.id;
or
string id = value.lastModifiedBy.application.id;
depending on your needs.
As it was pointed out, you'd need to fix your JSON first and remove the first { and the last }
First thing first, Your json is invalid.
You've to remove one { from top and } from the bottom and then use the following code:
dynamic jsonObj = JsonConvert.DeserializeObject(result);
string id = jsonObj.createdBy.application.id.ToString();
