How do I consume Api for C# project

I am trying to consume an Api for c# project.
I have the request body sample as follows:
{
"tx_ref":"hooli-tx-1920bbtytty",
"amount":"100",
"currency":"NGN",
"redirect_url":"https://webhook.site/9d0b00ba-9a69-44fa-a43d-a82c33c36fdc",
"payment_options":"card",
"meta":{
"consumer_id":23,
"consumer_mac":"92a3-912ba-1192a"
},
"customer":{
"email":"user#gmail.com",
"phonenumber":"080****4528",
"name":"Yemi Desola"
},
"customizations":{
"title":"Pied Piper Payments",
"description":"Middleout isn't free. Pay the price",
"logo":"https://assets.piedpiper.com/logo.png"
}
}
I want to convert the code to C#, I did it as below, but the "meta", "customer", "customizations" are nested in the request, when I tried to reproduce the nested part of the code to c# I get an error.
Please how do I place my C# code to reflect the body with the nested part of the code?
var keyValues = new Dictionary<string, string>
{
{ "tx_ref", "N-872653uy09-9"},
{ "amount", "500"},
{ "currency","NGN"},
{ "redirect_url","mysite.com/ConcludeFunding.aspx"},
{ "payment_options","card"},
{ "meta"," "},
{ "customer"("email",EmailV) },
{ "customizations","mysite.com/Assets/Logo.jpg"},
};
//serialization using Newtonsoft JSON
string JsonBody = JsonConvert.SerializeObject(keyValues);

For this type of situation, I would create a root class. Then I would assign value to the class object and finally I would serialize the object using Newtonsoft JSON.
Code:
using Newtonsoft.Json;
using System;
namespace Solve
{
internal class Program
{
public class Meta
{
public int consumer_id { get; set; }
public string consumer_mac { get; set; }
}
public class Customer
{
public string email { get; set; }
public string phonenumber { get; set; }
public string name { get; set; }
}
public class Customizations
{
public string title { get; set; }
public string description { get; set; }
public string logo { get; set; }
}
public class Root
{
public string tx_ref { get; set; }
public string amount { get; set; }
public string currency { get; set; }
public string redirect_url { get; set; }
public string payment_options { get; set; }
public Meta meta { get; set; }
public Customer customer { get; set; }
public Customizations customizations { get; set; }
}
static void Main(string[] args)
{
var rootObj = new Root()
{
tx_ref = "N-872653uy09-9",
amount = "500",
currency = "NGN",
redirect_url = "mysite.com/ConcludeFunding.aspx",
payment_options = "card",
meta = new Meta()
{
consumer_id = 23,
consumer_mac = "92a3-912ba-1192a"
},
customizations = new Customizations()
{
title = "Pied Piper Payments",
description = "Middleout isn't free. Pay the price",
logo = "https://assets.piedpiper.com/logo.png"
},
customer = new Customer()
{
email = "user#gmail.com",
phonenumber = "080****4528",
name = "Yemi Desola"
}
};
string json = JsonConvert.SerializeObject(rootObj);
Console.WriteLine(json);
}
}
}

C# - Store JSON array string into SQL table

I am new to C#
Following is the JSON string I am getting from the web API.
I am trying to store the JSON string into a class and then store the JSON string into an SQL table.
But the C# code is failing to deserialize JSON into class. And the message box returns the null exception error.
JSON
{
"Count":3,
"data":[
{
"Cost1":{
"amount":111,
"currencyCode":"ABC"
},
"Cost2":{
"amount":22.2,
"currencyCode":"XYZ"
},
"Id":"007"
},
{
"Cost1":{
"amount":555,
"currencyCode":"ABC"
},
"Cost2":{
"amount":444,
"currencyCode":"XYZ"
},
"Id":"008"
},
{
"Cost1":{
"amount":666,
"currencyCode":"ABC"
},
"Cost2":{
"amount":8882,
"currencyCode":"XYZ"
},
"Id":"009"
}
],
"pending":[
],
"#up":"Test Data"
}
C# Code
public class ParceJSN {
public int Count {
get;
set;
}
public string data {
get;
set;
}
public string pending {
get;
set;
}
public string up {
get;
set;
}
}
public void Main() {
Task < string > task = MakeRequest(db_token); //Returns the JSON string
var fr = task.Result;
ParceJSN rst = JsonConvert.DeserializeObject < ParceJSN > (fr.ToString());
MessageBox.Show(rst.TotalCount.ToString());
Dts.TaskResult = (int) ScriptResults.Success;
}

Your C# model is incorrect. Here's a really handy tool that I use when I need to generate C# classes based on some JSON - json2csharp.com
The correct class is:
public class Cost1 {
public int amount { get; set; }
public string currencyCode { get; set; }
}
public class Cost2 {
public double amount { get; set; }
public string currencyCode { get; set; }
}
public class Datum {
public Cost1 Cost1 { get; set; }
public Cost2 Cost2 { get; set; }
public string Id { get; set; }
}
public class Root {
public int Count { get; set; }
public List<Datum> data { get; set; }
public List<object> pending { get; set; }
[JsonProperty("#up")]
public string Up { get; set; }
}
Now that you have the correct model, you can now do the following to deserialize your JSON string into a Root object which is defined above:
Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(YOUR_JSON_STRING);

C# Deserialize Facebook JSON starting with random key

Hello still a newb (student) to C#, I was wondering how to deserialize this kind of JSON data (with JsonConvert and a model class)
JSON example:

This is what you have to do.
Step 1: Convert your json to Dictionary.
var dataDictionary = JsonConvert.DeserializeObject<Dictionary<string, FBModel>>(yourJsonstring);
Step 2: Then get list of object
List<FBModel> data=new List<FBModel>();
foreach (var item in dataDictionary)
{
data.Add(item.Value);
}
Step 2 can be done as a linq query
List<FBModel> data= dataDictionary.Select(item => item.Value).ToList();
Update
your class structure should be like below to access the event data.
public class FBModel
{
public string ID { get; set; }
public string Name { get; set; }
public Events Events { get; set; }
public override string ToString()
{
return ID + ": " + Name;
}
}

{
public List<Data> Data { get; set; }
}

{
public string Description { get; set; }
public string End_Time { get; set; }
public string Name { get; set; }
public Place Place { get; set; }
public string Start_Time { get; set; }
public string Id { get; set; }
}

Json.Net serialise collection into named attributes

I am creating a Xamarin app with API calls managed by Refit and other Paul Betts libraries and was looking at serialising a collection of objects into a Json attributed array.
The question I have is how do I serialise the collection of MemberSlot objects in the MemberBooking type, using Json.Net, into the desired Json?
The names of the objects will always be numbers 1 -> 4 but some or all may not be present.
Question
Could I just change the List property in the MemberBooking object to a Dictionary and populate the string key appropriately?
Object heirarchy
public class MemberBookingRequest
{
[JsonProperty("member_booking_request")]
public MemberBooking Booking { get; set; }
}
public class MemberBooking
{
[JsonProperty("course_id")]
public int CourseId { get; set; }
[JsonProperty("date")]
public string TeeDate { get; set; }
[JsonProperty("time")]
public string TeeTime { get; set; }
[JsonProperty("slots")]
public List<MemberSlot> Slots { get; set; }
}
public class MemberSlot
{
[JsonIgnore]
public int Id { get; set; }
[JsonProperty("type")]
public BookingType Type { get; set; }
[JsonProperty("holes")]
public int Holes { get; set; }
[JsonProperty("user_id")]
public int MemberId { get; set; }
}
Current Json
{
"member_booking_request":{
"course_id":1,
"date":"2016-09-29",
"time":"09:00",
"slots":[
{
"type":"Member",
"holes":18,
"user_id":110
},
{
"type":"Member",
"holes":18,
"user_id":111
},
{
"type":"Member",
"holes":18,
"user_id":112
},
{
"type":"Member",
"holes":18,
"user_id":117
]
}
}
}
Desired Json
{
"member_booking_request":{
"course_id":1,
"date":"2016-09-29",
"time":"09:00",
"slots":{
"1":{
"type":"Member",
"holes":18,
"user_id":110
},
"2":{
"type":"Member",
"holes":18,
"user_id":111
},
"3":{
"type":"Member",
"holes":18,
"user_id":112
},
"4":{
"type":"Member",
"holes":18,
"user_id":117
}
}
}
}

You'll have to change the way you create Slots property. Assign MemberSlot.Id as key, MemberSlot itself as value when filling Slots dictionary.
public class MemberBooking
{
[JsonProperty("course_id")]
public int CourseId { get; set; }
[JsonProperty("date")]
public string TeeDate { get; set; }
[JsonProperty("time")]
public string TeeTime { get; set; }
[JsonProperty("slots")]
public Dictionary<int,MemberSlot> Slots { get; set; }
}

This sample will give the your desired json output,using a dictionary
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;
namespace jsonconversion
{
public class Program
{
public static void Main(string[] args)
{
Dictionary<int,MemberSlot> slots=new Dictionary<int, MemberSlot>();
MemberSlot slot1 = new MemberSlot() {Id = 1, Holes =2, MemberId = 1};
slots.Add(1,slot1);
MemberBookingRequest mbr = new MemberBookingRequest
{
Booking = new MemberBooking()
{CourseId = 1, TeeDate ="",TeeTime = "",Slots = slots}
};
string jd = JsonConvert.SerializeObject(mbr);
Console.WriteLine(jd);
}
}
public class MemberBookingRequest
{
[JsonProperty("member_booking_request")]
public MemberBooking Booking { get; set; }
}
public class MemberBooking
{
[JsonProperty("course_id")]
public int CourseId { get; set; }
[JsonProperty("date")]
public string TeeDate { get; set; }
[JsonProperty("time")]
public string TeeTime { get; set; }
[JsonProperty("slots")]
public Dictionary<int, MemberSlot> Slots { get; set; }
}
public class MemberSlot
{
[JsonIgnore]
public int Id { get; set; }
[JsonProperty("holes")]
public int Holes { get; set; }
[JsonProperty("user_id")]
public int MemberId { get; set; }
}
}

extract data from json in asp.net c#

I'm trying to extract some data from json. I've been looking for a solution either in JSS or Json.net but haven't been able to figure this problem out. this is how my Json looks like:
Note: i Have tested and the mapping and decentralization works! I'm looking for a way to extract specifc data from the json!

and I need to extract following information from my json.(from specific Task in may json! for example the first one with id : tmp_fk1345624806538 ).
Note: i'm getting my json from a json file as follow:
string startDate; // this is what i need to extract
string endDate; // this is what i need to extract
string Progress; // this is what i need to extract
public void load()
{
GC.GClass l = new GC.GClass();
string jsonString = l.load(); // i get my json from a json file
Rootobject project = JsonConvert.DeserializeObject<Rootobject>(jsonString);
}

You can use LINQ to query the object quickly.
Task task = project.tasks.FirstOrDefault(t=> t.id == "tmp_fk1345624806538");
Test task, and if null then there was not task with matching id. If you are sure that there will be a matching task your can just use .First(), but it will throw an exception if there is no match in the list
You'll need to add a using System.Linq; if you don't have that already.
