I want to create a C# object by parsing a Json string that contains embedded contianer objects. See StockHistory in the code snippet.
I tried defining the parent object in many ways the compiler would allowed. Like wrapping and not wrapping "KeyValue property" in a List, using a Dictionary, also, tring to defining the strings with single vs double quotation marks. Most Stackoverflow listings shows a list or dictionary as the parent object (contianer). But my containers are embedded.
However, if a custom converter is needed... I'm not sure on how to write it. A code snippet would be great. I can not change the Json… it's coming from a third-party server.
When I examine the json string with the Visual Studio 2017 JSON Visualizer (by highlighting the variable and clicking on the magnify grass) all appears good and as expected.
using Newtonsoft.Json; // I'm using NuGet vs: 12.0.0.0
using System;
using System.Collections.Generic;
namespace ConsoleApp1
{
class Program
{
public class StockHistory
{
public List<string> Meta_Data { get; set; }
public Dictionary<string, LHOCV> Lhocv { get; set; }
}
public class LHOCV
{
public float Low { get; set; }
public float High { get; set; }
public float Open { get; set; }
public float Close { get; set; }
public double Volume { get; set; }
}
static void Main(string[] args)
{
string json =
@"{
'Meta Data': {
'1. Information': 'Intraday (5min) ...',
'2. Symbol': 'MSFT',
'3. Last Refreshed': '2019-01-22 16:00:00',
'4. Interval': '5min',
'5. Output Size': 'Full size',
'6. Time Zone': 'US/Eastern'
},
'Time Series (5min)': {
'2019-01-22 16:00:00': {
'1. open': '105.2200',
'2. high': '105.8700',
'3. low': '105.1000',
'4. close': '105.8200',
'5. volume': '1619877'
},
'2019-01-22 15:50:00': {
'1. open': '105.4200',
'2. high': '105.4800',
'3. low': '105.2600',
'4. close': '105.3000',
'5. volume': '452625'
}
}
}";
StockHistory a = JsonConvert.DeserializeObject<StockHistory>(json);
// I can not get a value assigned to "a"... both container objects,
// Meta_Data and Lhocv, are rendered null.
//Console.WriteLine(a.Lhocv["2019-01-22 16:00:00"].High);
}
}
}
I expected the c# variable "a" (StockHistory), to contain the parsed JSON Keys and data for JSON fields "Meta Data" and "Time Series (5min)".
What I get are null values for the containers.
This might get you close:
public class StockHistory
{
[JsonProperty("Meta Data")]
public Dictionary<string, string> Meta_Data { get; set; }
[JsonProperty("Time Series (5min)")]
public Dictionary<string, LHOCV> Lhocv { get; set; }
}
public class LHOCV
{
[JsonProperty("3. low")]
public float Low { get; set; }
[JsonProperty("2. high")]
public float High { get; set; }
[JsonProperty("1. open")]
public float Open { get; set; }
[JsonProperty("4. close")]
public float Close { get; set; }
[JsonProperty("5. volume")]
public double Volume { get; set; }
}
