Easiest way to parse JSON response
(4 answers)
Closed 4 years ago.
string sample = "{\"warnings\":[{\"code\":3,\"message\":\"Invalid number\"}],\"errors\":[{\"code\":4,\"message\":\"No recipients specified\"}],\"status\":\"failure\"}";
JavaScriptSerializer js = new JavaScriptSerializer();
List<Status> liststatus = (List<Status>)js.Deserialize(sample, typeof(List<Status>));
string success = "";
foreach (Status status in liststatus)
{
success = status.code;
}
Response.Write("success");
public class Status
{
public string status { get; set; }
public string[] warnings { get; set; }
public string balance { get; set; }
public string message { get; set; }
public string recipient { get; set; }
public string content { get; set; }
public string num_messages { get; set; }
public string num_parts { get; set; }
}
i trying to convert json object to c# , but i didn't. what wrong with my code???
Your JSON string is not a list, its a object which has the properties of Warnings (List),
Create a model that matches it
JavaScriptSerializer js = new JavaScriptSerializer();
Status x = (Status)js.Deserialize(sample, typeof(Status);
Apparently, status.code is not to any code attribute in json.
It should be status.warnings[0].code or status.errors[0].code

My project has a 3rd party web API that returns a json string in the following format (including the starting and ending curly braces):
{
"866968030210604":{
"dt_server":"2019-02-07 12:21:27",
"dt_tracker":"2019-02-07 12:21:27",

"lat":"0",
"lng":"0",
"altitude":"0",
"angle":"0",
"speed":"0",
"params":null,
"loc_valid":"0"
}
}
I want to deserialize it into a c# class object for further processing. I made the following class structure for the same:
class Params
{
public string pump { get; set; }
public string track { get; set; }
public string bats { get; set; }
public string acc { get; set; }
public string batl { get; set; }
}
class GPSData
{
public string dt_server { get; set; }
public string dt_tracker { get; set; }
public string lat { get; set; }
public string lng { get; set; }
public string altitude { get; set; }
public string angle { get; set; }
public string speed { get; set; }
public Params ObjParams { get; set; }
public string loc_valid { get; set; }
}
and I am trying the following code to deserialize:
JavaScriptSerializer jSerObj = new JavaScriptSerializer();
List<GPSData> lstGPSData = (List<GPSData>)jSerObj.Deserialize(json, typeof(List<GPSData>));
But every time it is showing NULL values assigned to each property of the class after the Deserialize() method is called. Please help me on this.
Your json is not in list format so deserializing to List<> isn't work
So you need to deserialize it into Dictionary<string, GPSData> like
JavaScriptSerializer jSerObj = new JavaScriptSerializer();
Dictionary<string, GPSData> lstGPSData = (Dictionary<string, GPSData>)jSerObj.Deserialize(json, typeof(Dictionary<string, GPSData>));
Usage:
foreach (var item in lstGPSData)
{
string key = item.Key;
GPSData gPSData = item.Value;
}
Also, you can list all your GPSData from above dictionary like,
List<GPSData> gPSDatas = lstGPSData.Values.ToList();

I have an HttpClient that makes a call to a REST API.
var response = await client.PostAsync("Payments/CreditCard", content);
var contents = await response.Content.ReadAsStringAsync();
When I read the content of the response as a string, I get the following result:
"\"{\\\"ssl_card_number\\\":\\\"41**********9994\\\",\\\"ssl_exp_date\\\":\\\"1219\\\",\\\"ssl_amount\\\":\\\"50.00\\\",\\\"ssl_salestax\\\":\\\"\\\",\\\"ssl_invoice_number\\\":\\\"\\\",\\\"ssl_departure_date\\\":\\\"\\\",\\\"ssl_completion_date\\\":\\\"\\\",\\\"Test\\\":\\\"\\\",\\\"TestField\\\":\\\"TestValue\\\",\\\"ssl_result\\\":\\\"0\\\",\\\"ssl_result_message\\\":\\\"APPROVAL\\\",\\\"ssl_approval_code\\\":\\\"578380\\\",\\\"ssl_cvv2_response\\\":\\\"U\\\",\\\"ssl_avs_response\\\":\\\"G\\\",\\\"ssl_account_balance\\\":\\\"0.00\\\",\\\"ssl_txn_time\\\":\\\"04/09/2018 09:41:01 AM\\\",\\\"ssl_card_type\\\":\\\"CREDITCARD\\\"}\""
When I debug and inspect the value of the contents variable, it contains the following:
When I try to deserialize the string into a C# object using JSON.Net, I receive an exception, because the contents variable can't be converted to my C# object.
However, if I take the string from the Text Visualizer, I'm able to successfully convert it to my C# object.
Here's the class I'm trying to deserialize the string contents into:
public class PaymentResponse
{
public string ssl_account_balance { get; set; }
public string ssl_amount { get; set; }
public string ssl_approval_code { get; set; }
public string ssl_avs_response { get; set; }
public string ssl_card_number { get; set; }
public string ssl_card_type { get; set; }
public string ssl_completion_date { get; set; }
public string ssl_cvv2_response { get; set; }
public string ssl_departure_date { get; set; }
public string ssl_exp_date { get; set; }
public string ssl_invoice_number { get; set; }
public string ssl_result { get; set; }
public string ssl_result_message { get; set; }
public string ssl_salestax { get; set; }
public string ssl_txn_id { get; set; }
public string ssl_txn_time { get; set; }
}
Here's the code I use for deserializing:
paymentResponse = JsonConvert.DeserializeObject<PaymentResponse>(contents);
How can I get my contents variable to have the same value that appears in the Text Visualizer?
The data shown appears to be serialized twice.
In that case it would need to be deserialized twice.
First to string,
var json = JsonConvert.DeserializeObject<string>(contents);
and then to the desired type
var paymentResponse = JsonConvert.DeserializeObject<PaymentResponse>(json);
#Nkosi was right: first deserialize it to string and then to PaymentResponse:
var contents = "\"{\\\"ssl_card_number\\\":\\\"41**********9994\\\",\\\"ssl_exp_date\\\":\\\"1219\\\",\\\"ssl_amount\\\":\\\"50.00\\\",\\\"ssl_salestax\\\":\\\"\\\",\\\"ssl_invoice_number\\\":\\\"\\\",\\\"ssl_departure_date\\\":\\\"\\\",\\\"ssl_completion_date\\\":\\\"\\\",\\\"Test\\\":\\\"\\\",\\\"TestField\\\":\\\"TestValue\\\",\\\"ssl_result\\\":\\\"0\\\",\\\"ssl_result_message\\\":\\\"APPROVAL\\\",\\\"ssl_approval_code\\\":\\\"578380\\\",\\\"ssl_cvv2_response\\\":\\\"U\\\",\\\"ssl_avs_response\\\":\\\"G\\\",\\\"ssl_account_balance\\\":\\\"0.00\\\",\\\"ssl_txn_time\\\":\\\"04/09/2018 09:41:01 AM\\\",\\\"ssl_card_type\\\":\\\"CREDITCARD\\\"}\"";
var contentAsString = JsonConvert.DeserializeObject<string>(contents);
var paymentResponse = JsonConvert.DeserializeObject<PaymentResponse>(contentAsString);
Console.WriteLine(paymentResponse.ssl_card_number);
Check the fiddle.
Here is the solution. Actually we need to take care about the Encoding while deserializing to object. Since the content string of the object would sometimes have other than ASCII charset. It worked fine for me.
var resultBytes = await response.Content.ReadAsByteArrayAsync();
var actualEncodedString = Encoding.UTF8.GetString(resultBytes);
var actualObject = JsonConvert.DeserializeObject<T>(actualEncodedString);

Parse JSON in C#
(7 answers)
Closed 6 years ago.
I have this string
[
{
"url_short":"http:\/\/sample.com\/8jyKHv",
"url_long":"http:\/\/www.sample.com\/",
"type":0
}
]
What I want is to get http:\/\/sample.com\/8jyKHv and translate it to
http://sample.com/8jyKHv
Is it possible?
This string is JSON.
You can parse it by using JSON.NET.
Example:
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class RootObject
{
public string url_short { get; set; }
public string url_long { get; set; }
public int type { get; set; }
}
public class Program
{
static public void Main()
{
string j = "[{\"url_short\":\"http:\\/\\/sample.com\\/8jyKHv\",\"url_long\":\"http:\\/\\/www.sample.com\\/\",\"type\":0}]";
List<RootObject> ro = JsonConvert.DeserializeObject<List<RootObject>>(j);
Console.WriteLine(ro[0].url_short);
}
}
Response:
http://sample.com/8jyKHv
Try this
Create a class like below
Note : you can use Paste Special option in visual studio to generate all the classes related to the JSON
Edit -> Paste Special -> Paste Json As Classes
it will create all the classes related to the JSON
public class url_details
{
public string url_short { get; set; }
public string url_long { get; set; }
public int type { get; set; }
}
public List<url_details> json_deserialized()
{
string json = "[{\"url_short\":\"http:\\/\\/sample.com\\/8jyKHv\",\"url_long\":\"http:\\/\\/www.sample.com\\/\",\"type\":0}]";
List<url_details> items = new List<url_details>();
items = JsonConvert.DeserializeObject<List<url_details>>(json);
return items;
}
And you can access the element like below
List<url_details> obj = json_deserialized();
string url_short = obj[0].url_short;
The JSON way is for sure recommended, but cant tell much about it. Here's the alternative way with regex:
Regex rgxUrl = new Regex("\"url_short\":\"(.*?)\",\"");
Match mUrl = rgxUrl.Match(yourString);
string url = Regex.Replace(mUrl.Groups[1].Value, #"\", "");
The string is a JSON string so you can create a class to get the values like this
public class Rootobject
{
public Class1[] Property1
{
get;
set;
}
}
public class Class1
{
public string url_short
{
get;
set;
}
public string url_long
{
get;
set;
}
public int type
{
get;
set;
}
}
After this class you can get the data like this
string json = "[{"url_short":"http:\/\/sample.com\/8jyKHv","url_long":"http:\/\/www.sample.com\/","type":0}]";
List<Rootobject> ro = JsonConvert.DeserializeObject<List<Rootobject>>(json);
string ururl = ro[0].Propert1[0].url_short;
I have a response from Jira API, require to be deserialized into data model:
com.atlassian.greenhopper.service.sprint.Sprint#40675167[id=10151,rapidViewId=171,state=CLOSED,name=Sprint 37.1,startDate=2015-07-30T16:00:22.000+03:00,endDate=2015-08-13T16:00:00.000+03:00,completeDate=2015-08-13T14:31:34.343+03:00,sequence=10151]
This is actually the information of current sprint for issue.
I need to deserialize it to a model like:
public class Model
{
public string name { get; set; }
...
}
I have already removed all non-required information, like com.atlassian.greenhopper.service.sprint.Sprint#40675167 using Regex pattern \[(.*?)\] so I have brackets and all inside.
Now I stopped completely trying to find the a way to convert this string to a data model.
Found the following thread at the Atlassian Answers page and there appears to be no JSON representation of that inner Object. As shown in the example from that thread:
customfield_10007:[
"com.atlassian.greenhopper.service.sprint.Sprint#a29f07[rapidViewId=<null>,state=CLOSED,name=NORD - Sprint 42,startDate=2013-07-29T06:47:00.000+02:00,endDate=2013-08-11T20:47:00.000+02:00,completeDate=2013-08-14T15:31:33.157+02:00,id=107]",
"com.atlassian.greenhopper.service.sprint.Sprint#769133[rapidViewId=<null>,state=ACTIVE,name=NORD - Sprint 43,startDate=2013-08-14T15:32:47.322+02:00,endDate=2013-08-23T15:32:47.322+02:00,completeDate=<null>,id=117]"
],
The response is indeed a JSON array, but the array itself contains CSV's, so you can make use of the following to parse that:
public class DataObject
{
public string id { get; set; }
public string rapidViewId { get; set; }
public string state { get; set; }
public string name { get; set; }
public string startDate { get; set; }
public string endDate { get; set; }
public string completeDate { get; set; }
public string sequence { get; set; }
}
public class Program
{
private const string sampleStringData =
#"[id=10151,rapidViewId=171,state=CLOSED,name=Sprint 37.1,startDate=2015-07-30T16:00:22.000+03:00,endDate=2015-08-13T16:00:00.000+03:00,completeDate=2015-08-13T14:31:34.343+03:00,sequence=10151]";
static void Main(string[] args)
{
var dataObject = new DataObject();
string[][] splitted;
var sampleWithNoBrackets = sampleStringData.Substring(1,sampleStringData.Length-2);
splitted = sampleWithNoBrackets.Split(',').Select(p => p.Split('=')).ToArray();
dataObject.id = splitted[0][1];
dataObject.rapidViewId = splitted[1][1];
dataObject.state = splitted[2][1];
dataObject.name = splitted[3][1];
dataObject.startDate = splitted[4][1];
dataObject.endDate = splitted[5][1];
dataObject.completeDate = splitted[6][1];
dataObject.sequence = splitted[7][1];
Console.ReadKey();
}
}
Here's the output for the above:

I am getting this error
Unexpected character encountered while parsing value: S. Path '', line 0, position 0.
Message is json object not list. You must have integrated serializer or serialize json object in action manually.
I think it must look like this:
public ActionResult action(Object Message)
{
// deserialise if Object Message is a string
var serializer = new JavaScriptSerializer();
var c = serializer.Deserialize<YourClass>(Message);
// deserialise if Object Message is a JsonObject
var serializer = new DataContractJsonSerializer(typeof(YourClass));
var c = (YourClass)serializer.ReadObject(Message);
return PartialView(Message);
}
or another solution:
I use library Newtonsoft.Json. If you're going to use it in your case it would look like:
...
MyClass m = JsonConvert.DeserializeObject<Message>(message.ToString());
var status = m.Status; //...and so on
