ASP.net mvc API get request and JSON data

Question

Trying to call a weather API using a service for asp.net mvc.

I have a Weather class that looks like this:

public class Weather
{
    public string main { get; set; }
    public string description { get; set; }
}

The method I am using to make the GET request looks like this:

    async public static Task<List<Weather>> GetWeather()
    {
        List<Weather> weatherData = new List<Weather>();

        HttpClient client = new HttpClient();
        HttpResponseMessage response = await client.GetAsync("http://api.openweathermap.org/data/2.5/weather?lat=35&lon=139&APPID=[MYKEY]");

        HttpContent content = response.Content;

        string data = await content.ReadAsStringAsync();
    }

The URI I'm requesting returns JSON objects.

{
  "coord": {
    "lon": 139,
    "lat": 35
  },
  "weather": [
    {
      "id": 804,
      "main": "Clouds",
      "description": "overcast clouds",
      "icon": "04n"
    }
  ],
  "base": "stations",
  "main": {
    "temp": 299.26,
    "pressure": 1007,
    "humidity": 83,
    "temp_min": 296.15,
    "temp_max": 301.15
  },
  "visibility": 16093,
  "wind": {
    "speed": 5.1,
    "deg": 330,
    "gust": 7.2
  },
  "clouds": {
    "all": 90
  },
  "dt": 1533638820,
  "sys": {
    "type": 1,
    "id": 7618,
    "message": 0.0028,
    "country": "JP",
    "sunrise": 1533585473,
    "sunset": 1533634868
  },
  "id": 1851632,
  "name": "Shuzenji",
  "cod": 200
}

I want to access the "weather" object and extract the properties main and description and in my GetWeather return a list where the weather properties from the JSON object match the properties in my class Weather.

I'm lost on what to do with the string data and how to get the JSON data into my List<Weather>.

EDIT

Tried to use JObject.Parse() as mentioned in the answer below but get an error Cannot perform runtime binding on a null reference when trying to print it to the console.

async public static Task<List<Weather>> GetWeather()
        {

            HttpClient client = new HttpClient();
            HttpResponseMessage response = await client.GetAsync("http://api.openweathermap.org/data/2.5/weather?lat=35&lon=139&APPID=[MYKEY]");

            HttpContent content = response.Content;

            string data = await content.ReadAsStringAsync();

            dynamic d = JObject.Parse(data);
            var main = d.main.ToString();
            var description = d.description.ToString();

            var weatherData = new List<Weather>
            {
                new Weather { Main = main,
                              Description = description }
            };

            Console.WriteLine(weatherData);

            return weatherData;
        }

Steps to access value of description from your json

Create model class for given json string, Visual studio provided option for it

Edit -> Paste special -> Paste JSON As class

class look like

public class MyClass
{
    public class Coord {
       public int lon { get; set; }
       public int lat { get; set; } }

    public class Weather {
       public int id { get; set; }
       public string main { get; set; }
       public string description { get; set; }
       public string icon { get; set; } }
 ...

Use NewtonSoft.JSON library to deserialize json

MyClass temp = JsonConvert.DeserializeObject<MyClass >(jsonString);

Now you can access description property of Weather class by

string output = temp.Weather.description

You want to look into deserializing the json. The easiest way for an example (although not as maintainable) would be to dump the json into a dynamic and pull the fields you want;

dynamic d = JObject.Parse(data);
var description = d.description.ToString();

If you create classes to match the JSON (it looks like your Weather class doesn't quite match - main is a nested object and not a string) then you can use Json.DeserializeObject< Weather >(data)
