I don't know what I'm doing wrong. I'm trying to copy the attribute part from the video but it's not working.

I've rewatched the video and checked the documentation but it's not working. I don't even understand what I'm doing wrong.

Program.cs
using System;
using System.IO;
using System.Collections.Generic;
using Newtonsoft.Json;

namespace Treehouse.CodeChallenges
{
    public class Program
    {
        public static void Main(string[] arg)
        {
        }

       public static WeatherForecast ParseWeatherForecast(string[] values)
       {
            var weatherForecast = new WeatherForecast();
            weatherForecast.WeatherStationId = values[0];
            DateTime timeOfDay;
            if (DateTime.TryParse(values[1], out timeOfDay))
            {
                weatherForecast.TimeOfDay = timeOfDay;
            }
            Condition condition;
            if (Enum.TryParse(values[2], out condition))
            {
                weatherForecast.Condition = condition;
            }
            int temperature;
            if (int.TryParse(values[3], out temperature))
            {
                weatherForecast.Temperature = temperature;
            }
            double precipitation;
            if (double.TryParse(values[4], out precipitation))
            {
                weatherForecast.PrecipitationChance = precipitation;
            }
            if (double.TryParse(values[5], out precipitation))
            {
                weatherForecast.PrecipitationAmount = precipitation;
            }
            return weatherForecast;
        }

        public static List<WeatherForecast> DeserializeWeather(string fileName)
        {
            var weatherForecasts = new List<WeatherForecast>();

            using (var reader = new StreamReader(fileName))
            using (var jsonReader = new JsonTextReader(reader))
            {
                var serializer = new JsonSerializer();
                weatherForecasts = serializer.Deserialize<List<WeatherForecast>>(jsonReader);
            }

            return weatherForecasts;
        }
    }
}
WeatherForecast.cs
using System;

namespace Treehouse.CodeChallenges
using Newtonsoft.Json

{
    public class WeatherForecast
    {
        [JsonProperty(WeatherStationId= "weather_station_id")]
        public string WeatherStationId { get; set; }
        public DateTime TimeOfDay { get; set; }
        public Condition Condition { get; set; }
        public int Temperature { get; set; }
        public double PrecipitationChance { get; set; }
        public double PrecipitationAmount { get; set; }
    }

    public enum Condition
    {
        Rain,
        Cloudy,
        PartlyCloudy,
        PartlySunny,
        Sunny,
        Clear
    }
}

Ultan,

1) Double check the placement of your using directive for the "Newtonsoft.Json" namespace.

2) Double check the syntax of the JsonProperty attribute.

Thanks ~James

Thanks again James, I worked it out by trial and error. Mostly error
