I am having difficulty replacing the Dark Sky API with Open weather. GPS Location works and is received through another azure function.The Dark Sky Api call still works too. It might be something little but I'm not sure what's wrong. The only significant difference from the Dark Sky Api is the data model. Yet, Postman keeps responding with null values.
Postman response:
{
"id": 0,
"main": null,
"description": null,
"icon": null
}
public interface IWeatherService
{
Task<Weather> GetWeatherAsync(double latitude, double longitude);
}
public class WeatherService : IWeatherService
{
private readonly HttpClient _client;
private readonly ILogger<IWeatherService> _logger;
public WeatherService(HttpClient client, ILogger<IWeatherService> logger)
{
_client = client;
_client.BaseAddress = new Uri("https://api.openweathermap.org/data/2.5/weather?");
_client.Timeout = TimeSpan.FromSeconds(10);
_logger = logger;
}
public async Task<Weather> GetWeatherAsync(double latitude, double longitude)
{
Weather retval = null;
try
{
if (latitude.Equals(0) || longitude.Equals(0))
return null;
var key = "HIDDEN";
// var API = Environment.GetEnvironmentVariable("WeatherKey");
var exclude = "minutely,hourly,daily,alerts";
var units = "imperial";
var requestUrl = $"&lat={latitude}&lon={longitude}&exclude={exclude}&units={units}&appid={key}";
var response = await _client.GetAsync(requestUrl);
var result = response.Content.ReadAsStringAsync().Result;
var weather = JsonConvert.DeserializeObject<Weather>(result);
retval = weather;
//}
//handler.Dispose();
}
catch (Exception ex)
{
_logger.LogError(ex, $"Error in {nameof(GetWeatherAsync)}");
}
return retval;
}

I'm new here so thanks for the great content; invaluable stuff.
I'm deserializing some Json from TDAmeritrade into a C# desktop app using the "Option Chain" api.
Depending on the input to the api, I can get a response with multiple expiration dates, multiple strike prices, and multiple option objects.
Here's a link to a typical response: API ResponseTDAmeritrade Json Example
A snippet of the problem code:
"numberOfContracts": 8,
"putExpDateMap": {
**"2020-08-21:50": {
"15.0":** [
{
"putCall": "PUT",
"symbol": "FMCI_082120P15",
"description": "FMCI Aug 21 2020 15 Put",
"exchangeName": "OPR",
The problem is that the dates and strike prices change in each response. I've learned that I can deserialize into a "Dictionary<string, List<Type> listName" so I did that in the OptionChain and ExpDate classes but still can't get it working.
Here is the current error: error trace
Here are my classes, created from json2csharp.com but with the date and strike price classes modified:
class OptionChain
{
public string symbol { get; set; }
public string status { get; set; }
public Underlying underlying { get; set; }

public class OptionDeliverablesList
{
public string symbol { get; set; }
public string assetType { get; set; }
public double deliverableUnits { get; set; }
public string currencyType { get; set; }
}
Am I doing something wrong in the Dictionaries? The way I understand it from my many hours of reading, the expiration dates and strike prices need to be read anonymously.
Thanks a bunch!
If I get your problem right - you have probelms deserializing json structure where keys are dynamic values but not static property names, correct? If so- you have modeled incorrect POCO (there are two nested dictionaries).
POCOs below give correct deserialization results (rest of properties skipped)
class OptionChain
{
public string Symbol { get; set; }
public string Status { get; set; }
public Dictionary<string, Dictionary<string, ExpDate[]>> PutExpDateMap { get; set; }
public Dictionary<string, Dictionary<string, ExpDate[]>> CallExpDateMap { get; set; }
//other properties ignored because dont matter
}
class ExpDate
{
public string ExchangeName { get; set; }
public decimal Bid { get; set; }
public decimal Ask { get; set; }
//other properties ignored because dont matter
}
Tested POCOs with json sample provided in your post:
static void Main(string[] args)
{
var t = File.ReadAllText("test.json");
var r = JsonConvert.DeserializeObject<OptionChain>(t);
Console.WriteLine($"Total elements in {nameof(r.PutExpDateMap)} : {r.PutExpDateMap.Count()}");
Console.WriteLine($"Keys in {nameof(r.PutExpDateMap)} : {string.Join(",", r.PutExpDateMap.Keys)}");
Console.WriteLine($"Total elements in {nameof(r.CallExpDateMap)} : {r.CallExpDateMap.Count()}");
Console.WriteLine($"Keys in {nameof(r.CallExpDateMap)} : {string.Join(",", r.CallExpDateMap.Keys)}");
}
Application output is:
I'm setting up a website ASPX file that grabs the weather for the next 3 days, the output is in JSON and their classes are too complicated for me to understand it. If I want to extract just the weather for the next 3 days how do I go on about doing that?
https://samples.openweathermap.org/data/2.5/forecast?q=London,us&appid=b6907d289e10d714a6e88b30761fae22
This is the JSON output displayed on top.
What I'm trying to accomplish is to extract the next 3 days of the weather "Description" and put it to a GridView. I have used a JSON beautifier to get the classes but I am still confused.
Any help would be appreciated
This is my current code and I'm stuck here
protected void Button1_Click(object sender, EventArgs e)
{
string searchTerm = TextBox1.Text;
var webRequest = (HttpWebRequest)WebRequest.Create("https://samples.openweathermap.org/data/2.5/forecast?q=" + Server.UrlEncode(searchTerm) + "&units=metric&APPID=b6907d289e10d714a6e88b30761fae22");
var webResponse = (HttpWebResponse)webRequest.GetResponse();
if (webResponse.StatusCode == HttpStatusCode.OK)
{
Label1.Text = "The Next 3 days of weather in your area in" + searchTerm + " .";
JavaScriptSerializer json = new JavaScriptSerializer();
StreamReader sr = new StreamReader(webResponse.GetResponseStream());
string resString = sr.ReadToEnd();
});
GridView1.DataSource = ?;
GridView1.DataBind();
}
else
Label.Text = "Invalid Response";

I am new at programming and I try to make exchange office in C# console application. I use free API service for current currency rates. On this way i can read all API elements, but i don't know how to take elements what i need? For example i need to take USDEUR rate. How to do that?
My code is
string url = #"http://apilayer.net/api/live? access_key=8efc5a54419e913b695f694bbef4d97f& currencies = EUR,GBP,CAD,PLN& source = USD& format = 1";
string objects = new WebClient().DownloadString(url);
var lista = JsonConvert.SerializeObject(objects, Formatting.Indented);
var finish = lista.ToArray();
Console.WriteLine(finish);
You need to let JSON string be object.
There are two way you can make it
use JsonConvert.DeserializeObject method to get model.

Note:
There are two way can create model easily.
You can use Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class, you can easier to know the relation between Json and model.
If you can't use Web Essentials you can instead http://json2csharp.com/ online JSON to Model class.
I'm trying to grab the high and low from this api, I am able to get the High, but can't figure out what to do to get the Low, which is the second occurring item with the name "fahrenheit", how could I do this using the same method I used for getting the High?
if (xmlForecast.Name == "fahrenheit" && i == 0)
{
i++;
xmlHigh = xmlForecast.ReadString();
}
Since you want solution using XML response, here it is:
First, you'll need to create classes which will represent XML response.

Secondly, you need to deserialize XML into Response
using (HttpClient client = new HttpClient())
{
using (var stream = await client.GetStreamAsync("http://api.wunderground.com/api/ea4bb7e7839782da/forecast/q/CA/San_Francisco.xml"))
{
var serializer = new XmlSerializer(typeof(Response));
var response = (Response)serializer.Deserialize(stream);
var simpleForecast = response.Forecast.SimpleForecast;
var forecastDays = simpleForecast.ForecastDays;
var latestForecastDay = forecastDays.Last();
var latestHighFahrenheit = latestForecastDay.High.Fahrenheit;
var latestLowFahrenheit = latestForecastDay.Low.Fahrenheit;
}
}
I am using XmlSerializer but you can also use DataContractSerializer which is newer. If you decide to use DataContractSerializer keep in mind that you'll need to replace XmlElement attributes with DataContract and DataMember.
Note: I've intentionally added few unnecessary steps and variable declarations, so you can see clearly what's going on here.
I am trying to deserialize a json feed from openweathermap.org api. After a lot of tries all, using script transformation task, I get is errors and even different ones. Based on the below classes generated by JSON, how I should write the for each statements (as class Weather and Main are part of class RootObject)?
I can get even XML data from api, instead of JSON. Would it be easier to implement the process?
I am not asking for the answer, just a push to start.
