TorontoWeather

The TorontoWeather project is an assignment created as part of Assignment 3 for the course 2024F CSD 3354 4 [B125] Web Applications Using C#.NET, under the guidance of the instructor. This project was developed by Preet Ojha (C0904332).

Overview

This project contains a WeatherService class that fetches weather information for Toronto using the Open-Meteo API. The service retrieves the daily maximum temperatures for Toronto and includes the corresponding day names for each temperature.

Features

• Fetches weather data asynchronously using the Open-Meteo API.
• Retrieves daily maximum temperatures for Toronto.
• Includes the day of the week (e.g., Monday, Tuesday) for each temperature.
• Parses the JSON response with Newtonsoft.Json (JObject) for easier data manipulation.

Requirements

• .NET 5 or later.
• Internet access to fetch data from the Open-Meteo API.
• Newtonsoft.Json for JSON parsing.

Getting Started

Install Dependencies

Before using the WeatherService class, ensure that your project includes the necessary dependencies. Install Newtonsoft.Json via NuGet:

dotnet add package Newtonsoft.Json

Example Usage

using System;
using System.Threading.Tasks;

namespace TorontoWeather
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var weatherService = new WeatherService();
            var weatherData = await weatherService.GetTorontoWeatherAsync();

            Console.WriteLine($"Toronto Weather Data:\n{weatherData}");
        }
    }
}

How It Works

1. WeatherService Constructor
   Initializes the HttpClient used to send HTTP requests.

2. GetTorontoWeatherAsync() Method

   • Constructs the URL with the appropriate query parameters for latitude, longitude, daily max temperature, and timezone.
   • Sends an asynchronous GET request to fetch weather data in JSON format.
   • Returns a formatted string with the dates, day names, and corresponding maximum temperatures.

3. ExtractMaxTemperaturesAndDays() Method

   • Extracts the daily maximum temperatures and the corresponding days from the parsed JSON response.
   • Converts the date string to a DateTime object to determine the day of the week.
   • Builds a formatted string that displays each date, its day of the week, and its corresponding maximum temperature in Celsius.

Sample Output

Toronto Weather Data:
2024-11-08 (Friday): 12.3°C
2024-11-09 (Saturday): 13.5°C
2024-11-10 (Sunday): 14.6°C
2024-11-11 (Monday): 15.2°C
2024-11-12 (Tuesday): 16.1°C

API Details

The service uses the Open-Meteo API to fetch weather data. Specifically, it requests:

• latitude: 43.7 (Toronto's latitude).
• longitude: -79.42 (Toronto's longitude).
• daily: temperature_2m_max (daily maximum temperature).
• timezone: America/Toronto (to get the weather data in the Toronto timezone).

For more information on the Open-Meteo API, visit the Open-Meteo Documentation.
