C# C# Streams and Data Processing Serialization Cleaning up the Player Class

please help me

Add the JsonProperty attribute to the PrecipitationChance property so that the JsonSerializer will correctly serialize it from "precipitation_chance". Then, also add the JsonProperty attribute to the PrecipitationAmount property so that the serializer will correctly serialize it from "precipitation_amount".

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;
using Newtonsoft.Json;

namespace Treehouse.CodeChallenges
{
    public class WeatherForecast
    {
        [JsonProperty("weather_station_id")]
        public string WeatherStationId { get; set; }
       [JsonProperty(PropertyName = "time_of_day")]
        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
    }

In task 3 you will add attributes exactly as you did already for tasks 1 and 2. The only difference is the placement and field names, and that this step asks for two of them instead of just one.

I know you can do it, give it another shot. Just take a look back at what you did for the first 2 tasks.
