I am trying to deserialize the string input in Azure function app. My input is
[{"messageid":1,
"deviceid":"Android",
"temperature":20.0,
"humidity":47.0,
"eventprocessedutctime":"2017-12-01T10:35:57.8331048Z",
"result1":{"temperature":"20","humidity":"47","Scored Labels":"NO","Scored Probabilities":"0.450145334005356"}}]
I tried to run with this code.
#r "Newtonsoft.Json"
using System.Configuration;
using System.Text;
using System.Net;
using Microsoft.Azure.Devices;
using Newtonsoft.Json;
// create proxy
static Microsoft.Azure.Devices.ServiceClient client = ServiceClient.CreateFromConnectionString(ConfigurationManager.AppSettings["myIoTHub"]);
public static async Task<HttpResponseMessage> Run(string input, HttpRequestMessage req, TraceWriter log)
{
log.Info($"ASA Job: {input}");
var data = JsonConvert.DeserializeAnonymousType(input, new { deviceid = "" });
if (!string.IsNullOrEmpty(data?.deviceid))
{
string deviceId = data.deviceid;
// string deviceId = data[0].deviceid;
log.Info($"Device: {deviceId}");
// cloud-to-device message
var msg = JsonConvert.SerializeObject(new { input });
var c2dmsg = new Microsoft.Azure.Devices.Message(Encoding.ASCII.GetBytes(msg));
// send AMQP message
await client.SendAsync(deviceId, c2dmsg);
}
return req.CreateResponse(HttpStatusCode.NoContent);
}
My interest is the deviceid and Scored Labels. But for now I can't even extract one of them. Some more the Scored Labels consists of space. The result1 is the result returned by Azure machine learning so it seems like can't be renamed.
Your problem is that your root JSON container is an array, not an object:
An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma).
An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace).
As explained in the Json.NET docs, a JSON array needs to be deserialized into a collection, such as a .Net array. Thus you can do:
var dataArray = JsonConvert.DeserializeAnonymousType(input, new [] { new { deviceid = "" } });
var data = dataArray.SingleOrDefault();
Sample fiddle.
If you find you need to extract more than just one or two properties from your JSON, you may want to create explicit type(s) into which to deserialize. To do this you could use http://json2csharp.com/ or Paste JSON as Classes.

I'm looking to change a specific property for each json record in my json file. I'd like to change the "Completed" property to "true" when a method finishes executing.
My json file looks like:
{
"LoanRecords": [
{
"LoanGUID": "{70dbec7e-5e94-460d-831c-0a5dc2d085e2}",
"RecordDT": "2020-11-10T14:44:34.378Z",
"Completed": "false",
"Environment": "TEBE",
"ProcessType": "RateLock"
},
{
"LoanGUID": "{70dbec7e-5e94-460d-831c-0a5dc2d085e2}",
"RecordDT": "2020-11-10T14:53:12.187Z",
"Completed": "false",
"Environment": "TEBE",
"ProcessType": "RateLock"
}
]
}
My C# code is the following:
private void ExecuteEvent(object sender, ElapsedEventArgs e)
{
string fileRecord = File.ReadAllText(jsonfile);
LoanRecordRoot LoanRecord = JsonConvert.DeserializeObject<LoanRecordRoot>(fileRecord);
foreach (var rec in LoanRecord.LoanRecords)
{
if (rec.Completed == "false")
{
bool recordModified = ManipulateEncompass(rec.LoanGUID, rec.ProcessType);
if (recordModified)
{
// What should I do here to update "rec.Completed" to "true"
// for this particular record and write it back to the json file
// for that specific entry?
}
}
}
Console.WriteLine("Successfully manipulated records!");
}
Is there a way to flip the "Completed" property to "true" for the specific record in my "foreach" iteration, and update the json file accordingly for that specific record? I am hoping to avoid reading the entire file, deserializing, changing the property then writing the entire content back to the json file, I'm looking to just flip that specific property for each record in my "foreach" loop. -- I hope that makes sense.
I've looked at similar questions, which seem close to what I'm looking for, but the examples I've seen don't reflect writing back to the json file specifically without overwriting the file contents -- unless this specific action isn't possible, or I'm failing to understand the entire process (highly possible.)
Ex of a solution that's close to what I'm looking for: How to update a property of a JSON object using NewtonSoft -- but doesn't seem to quite fit the bill for what I'm wanting to do.
Thank you in advance for any helpful leads!
you need to save the complete JSON when you update a property of an element of the array
static void Main(string[] args)
{
const string jsonPath = #"C:\Logs\recordRoot.json";
var loanRecordRoot = JsonConvert.DeserializeObject<LoanRecordRoot>(File.ReadAllText(jsonPath));
foreach (var record in loanRecordRoot.LoanRecords)
{
if (record.Completed == "false")
{
if (ManipulateEncompass(rec.LoanGUID, rec.ProcessType))
{
record.Completed = "true";
}
}
}
//Save Json
var json = JsonConvert.SerializeObject(loanRecordRoot, Formatting.Indented);
File.WriteAllText(jsonPath, json);
}
Looking at your JSON, it appears the "Completed" property is being serialized as of type string
Therefore, all you need to do is set it to "Completed": "true" within your condition in your snippet.
if (recordModified)
{
rec.Completed = "true";
}
At the end of your processing, simply serialize your LoanRecord object and write it back to your file.

I'm using Ubuntu and dotnet 3.1, running vscode's c# extension.
I need to create a List from a JSON file, my controller will do some calculations with this model List that I will pass to it
So, here is my code and the error I'm getting.
First, I thought my error was because at model my attributes were char and C#, for what I saw, cannot interpret double-quotes for char, it should be single quotes. Before losing time removing it, I just changed my type declarations to strings and it's the same error.
Can someone help me?
ElevadorModel
using System.Collections.Generic;
namespace Bla
{
public class ElevadorModel
{
public int andar { get; set; }
public string elevador { get; set; }
public string turno { get; set; }
}
}
Program.cs:
class Program
{
static void Main(string[] args)
{
var path = "../input.json";
string jsonString;
ElevadorModel elevadoresModel = new ElevadorModel();
jsonString = File.ReadAllText(path); //GetType().Name = String
Console.WriteLine(jsonString); //WORKS
elevadoresModel = JsonSerializer.Deserialize<ElevadorModel>(jsonString);
}
JSON:
Your input json has an array as the base token, whereas you're expecting an object. You need to change your deserialization to an array of objects.
var elevadoresModels = JsonSerializer.Deserialize<List<ElevadorModel>>(jsonString);
elevadoresModel = elavoresModels.First();
Your input JSON is an array of models, however you're trying to deserialize it to a single model.
var models = JsonSerializer.Deserialize<List<ElevadorModel>>(jsonString);
This is also a problem in Blazor-Client side. For those calling a single object
e.g ClassName = await Http.GetFromJsonAsync<ClassName>($"api/ClassName/{id}");
This will fail to Deserialize. Using the same System.Text.Json it can be done by:
List<ClassName> ListName = await Http.GetFromJsonAsync<List<ClassName>>($"api/ClassName/{id}");
You can use an array or a list. For some reason System.Text.Json, does not give errors and it is successfully able Deserialize.
To access your object, knowing that it is a single object use:
ListName[0].Property
In your case the latter solution is fine but with the path as the input.
In my case, I was pulling the JSON data to deserialize out of an HTTP response body. It looked like this:
var resp = await _client.GetAsync($"{endpoint}");
var respBody = await resp.Content.ReadAsStringAsync();
var listOfInstances = JsonSerializer.Deserialize<List<modelType>>(respBody);
And the error would show up. Upon further investigation, I found the respBody string had the JSON base object (an array) wrapped in double quotes...something like this:
"[{\"prop\":\"value\"},...]"
So I added
respBody = respBody.Trim('\"');
And the error changed! Now it was pointing to an invalid character '\'.
I changed that line to include
respBody = respBody.Trim('\"').Replace("\\", "");
and it began to deserialize perfectly.
For reference:
var resp = await _client.GetAsync($"{endpoint}");
var respBody = await resp.Content.ReadAsStringAsync();
respBody = respBody.Trim('\"').Replace("\\", "");
var listOfInstances = JsonSerializer.Deserialize<List<modelType>>(respBody);
Question Background:
Update:
I'm still not sure how to go about extracting the relevant information from this response. I have tried setting my response type to JSON but still receive the response as shown below. I have taken into account what has been said in regards to using NameValueCollection but still cant see how this will help with such a large response. Ideally I'd like this mapped to an object structure of some kind, it dosen't necessarily have to be JSON.
Question:
I'm currently using the PayPal Api 'ExpressCheckout' method to allow users to pay for items on my test site. A HTTP response from the API provides a large response containing key information I need to extract - such as the buyers address, if the payment was succesful etc.
The Issue:
Currently I'm stuck on how to work with the response. Ideally I'd convert the data to a JSON string then use Newtonsoft to map the data to C# classes thus allowing easy access to the data. Here is an example of the Httpresponse:
TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88%2e0&BUILD=14443165&EMAIL=test%40aol%2ecom&PAYERID=3XXXXXXXXXX4N&PAYERSTATUS=verified&BUSINESS=Test%20Biz%27s%20Test%20Store&FIRSTNAME=Joe&LASTNAME=King&COUNTRYCODE=GB&SHIPTONAME=Joe%20King%27s%20Test%20Store&SHIPTOSTREET=1%20Main%20Terrace&SHIPTOCITY=Wolverhampton&SHIPTOSTATE=West%20Midlands&SHIPTOZIP=W12%204LQ&SHIPTOCOUNTRYCODE=GB&SHIPTOCOUNTRYNAME=United%20Kingdom&ADDRESSSTATUS=Confirmed&CURRENCYCODE=GBP&AMT=15%2e56&ITEMAMT=15%2e56&SHIPPINGAMT=0%2e00&HANDLINGAMT=0%2e00&TAXAMT=0%2e00&INSURANCEAMT=0%2e00&SHIPDISCAMT=0%2e00&L_NAME0=ItemOne&L_QTY0=4&L_TAXAMT0=0%2e00&L_AMT0=3%2e89&L_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUEST_0_CURRENCYCODE=GBP&PAYMENTREQUEST_0_AMT=15%2e56&PAYMENTREQUEST_0_ITEMAMT=15%2e56&PAYMENTREQUEST_0_SHIPPINGAMT=0%2e00&PAYMENTREQUEST_0_HANDLINGAMT=0%2e00&PAYMENTREQUEST_0_TAXAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEAMT=0%2e00&PAYMENTREQUEST_0_SHIPDISCAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED=false&PAYMENTREQUEST_0_SHIPTONAME=Joe%20King%27s%20Test%20Store&PAYMENTREQUEST_0_SHIPTOSTREET=1%20Main%20Terrace&PAYMENTREQUEST_0_SHIPTOCITY=Wolverhampton&PAYMENTREQUEST_0_SHIPTOSTATE=West%20Midlands&PAYMENTREQUEST_0_SHIPTOZIP=W12%204LQ&PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE=GB&PAYMENTREQUEST_0_SHIPTOCOUNTRYNAME=United%20Kingdom&PAYMENTREQUEST_0_ADDRESSSTATUS=Confirmed&L_PAYMENTREQUEST_0_NAME0=ItemOne&L_PAYMENTREQUEST_0_QTY0=4&L_PAYMENTREQUEST_0_TAXAMT0=0%2e00&L_PAYMENTREQUEST_0_AMT0=3%2e89&L_PAYMENTREQUEST_0_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUESTINFO_0_ERRORCODE=0
If anyone could give me an easy way to map this data to a C# object that would be great.
Is there any specific reason why you want it in JSON format? If its not requirement and if you can live with key value pair then here is one way you can process response as key value pair.
public partial class Form1 : Form
{
Dictionary<string, string> processedResponse = null;
public Form1()

//Process response
processedResponse = ProcessResponse(rawResponse);
//Use received data e.g.
//Get First name
string fName = GetRecordValue("FIRSTNAME");
//Get Last name
string lName = GetRecordValue("LASTNAME");
}
private Dictionary<string,string> ProcessResponse(string response)
{
Dictionary<string, string> responseData = new Dictionary<string, string>();
if(!string.IsNullOrWhiteSpace(response))
{
string[] firstPass = response.Split(new char[] { '&' });
foreach(string pair in firstPass)
{
string[] secondPass = pair.Split(new char[] { '=' });
if(secondPass!=null && secondPass.Length>0)
{
responseData.Add(secondPass[0].Trim(), secondPass[1].Trim());
}
}
}
return responseData;
}
private string GetRecordValue(string record)
{
string recordValue = null;
if(processedResponse!=null)
{
if(!string.IsNullOrWhiteSpace(record) && processedResponse.ContainsKey(record))
{
recordValue= processedResponse[record];
}
}
return recordValue;
}
}
Still unsure what's the problem with dealing with it as a NameValueCollection.
E.g.
//NameValueCollection
//or use HttpUtility.ParseQueryString(some_string_of_names_values)
var foo = Request.QueryString;
var bar = foo["FIRSTNAME"]; //based on above this is "Joe"
Update:
It is response string which is being processed here and not request hence you wont be able to retrieve details using Request.QueryString
As stated in comments:
string rawResponse = "TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88...."
var foo = HttpUtility.ParseQueryString(rawResponse); //NameValueCollection
var bar = foo["FIRSTNAME"]; //Joe

I am running this code in C# in VS2013 which I got from here: http://tda.codeplex.com/. The code is supposed to gather data from my TD Ameritrade 401k account. The code is running fine but when I look in the output folder no file is saved. I keep getting this two errors that I am unable to fix. What am I doing wrong?
namespace TDAmeritrade.Samples

using System;
using TDAmeritrade;
class Program
{

{
// Initialize TD Ameritrade client, provide additional config info if needed
var client = new TDAClient();
// Log in to the TD Ameritrade website with your user ID and password
client.LogIn("jessicasusername", "jessicaspassword");
// Now 'client.User' property contains all the information about currently logged in user
var accountName = client.User.Account.DisplayName;
// Get stock quotes snapshot.
var quotes = client.GetQuotes("GOOG, AAPL, $SPX.X, DUMMY");

Error 1 A namespace cannot directly contain members such as fields or

this is because you declare some variable outside of a class. just put theme in class Program.

The way your code should be arranged is thus:
using System;
using TDAmeritrade;
namespace TDAmeritrade.Samples
{
class Program
{
const string SaveFileToLocation = #"C:\Users\jessica\Desktop\json_data";
static void Main()
{
// Initialize TD Ameritrade client, provide additional config info if needed
var client = new TDAClient();
// Log in to the TD Ameritrade website with your user ID and password
client.LogIn("jessicasusername", "jessicaspassword")
// Get historical prices
var prices = client.GetHistoricalPrices("GOOG, AAPL", StartDate: DateTime.Today.AddDays(-7), EndDate: DateTime.Today.AddDays(-1));
//You cannot create json until the prices variable has been declared!
string json = JsonConvert.SerializeObject(prices, Formatting.Indented);
using (StreamWriter writer = new StreamWriter(SaveFileToLocation))
{
writer.Write(json);
}
}
}
}
I'm trying to store data from fb wall into database.
My *.cs code
public ActionResult GetWall()
{
JSONObject wallData = helper.Get("/me/feed");
if (wallData != null)
{
var data = wallData.Dictionary["data"];
List<JSONObject> wallPosts = data.Array.ToList<JSONObject>();
ViewData["Wall"] = wallPosts;
}
return View("Index");
}
Which gets posts from fb wall.
And then I have an *.aspx file, which "breaks" my wallposts into pieces (objects) or whatever you like to call them.
foreach (Facebook.JSONObject wallItem in wallPosts)
{
string wallItemType = wallItem.Dictionary["type"].String;
//AND SO ON...
What i'm trying to say is that I can access to elements inside fb JSON.
Is there a way i can access to the JSON elements inside *.cs file.
Or is there a way I can store elements inside the *.aspx file to db?
And if its possible, I would like to know how. =)
Thanks for help
Don't use the SDK. Fetch the JSON Data using HttpWebRequest and then Deserialize it using System.Runtime.Serialization.Json.DataContractJsonSerializer. You just have to Create a class with same properties returned in JSON data. See the example below
string Response = Utilities.HttpUtility.Fetch("https://graph.facebook.com/me?access_token=" + AccessToken, "GET", string.Empty);
using (System.IO.MemoryStream oStream = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(Response)))
{
oStream.Position = 0;
return (Models.FacebookUser)new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(Models.FacebookUser)).ReadObject(oStream);
}
I'm not familiar with the facebook API and the question isn't too clear, but I assume that the string wallItemType is itself a JSON string, and you wish to parse it.
I'd use the Json.Net library to parse this.
using Newtonsoft.Json;
//your code as above
foreach (Facebook.JSONObject wallItem in wallPosts)
{
string wallItemType = wallItem.Dictionary["type"].String;
//I assume wallItemType is a JSON string {"name":"foobar"} or similar
JObject o = JObject.Parse(wallItemType);
string name = (string)o["name"]; //returns 'foobar'
//and so on
you can also use the Json.Net to deserialize to a custom type. This custom type could be mapped to a SQL database using NHibernate.
If you wish to store the entire json string in a database, then you could use a document database such as CouchDB.
