C# C# Streams and Data Processing Parsing Data Working with Enums

Did you pass the 'condition' variable to the TryParse method as an out parameter?

Everything looks just perfect. I checked for typing errors. What wrong with the code? I constantly get the same error. But I passed 'condition' variable to the TryParse method as an out parameter. Please, help!

Program.cs 
using System;
using System.IO;

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

        public static WeatherForecast ParseWeatherForecast(string[] values)
        {
            var weatherForecast = new WeatherForecast();
            DateTime timeOfDay;
            if (DateTime.TryParse(values[1], out timeOfDay))
            {
                weatherForecast.TimeOfDay = timeOfDay;
            }
            if (Enum.TryParse(values[2]), out condition) 
            {
                weatherForecast.Condition = condition;
            }
            return weatherForecast;
        }
    }
}
WeatherForecast.cs 
using System;

namespace Treehouse.CodeChallenges
{
    public enum Condition 
        {

    public class WeatherForecast
    {
        public string WeatherStationId { get; set; }
        public DateTime TimeOfDay { get; set; }
        public Condition Condition { get; set; }

    }
}

I solved it. Finally :) I put the parenthesis in a wrong place in Enum.TryParse. Here is the correct code:

Program.cs 
using System;
using System.IO;

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

        public static WeatherForecast ParseWeatherForecast(string[] values)
        {
            var weatherForecast = new WeatherForecast();
            DateTime timeOfDay;
            if (DateTime.TryParse(values[1], out timeOfDay))
            {
                weatherForecast.TimeOfDay = timeOfDay;
            }
            Condition condition;
            if (Enum.TryParse(values[2], out condition)) 
            {
                weatherForecast.Condition = condition;
            }
            return weatherForecast;
        }
    }
}
WeatherForecast.cs 
using System;

/* Sample CSV Data 

weather_station_id,time_of_day,condition,temperature,precipitation_chance,precipitation_amount
HGKL8Q,06/11/2016 0:00,Rain,53,0.3,0.03

namespace Treehouse.CodeChallenges
{
    public enum Condition 
        {
            Rain,
            Cloudy,
            PartlyCloudy,
            PartlySunny,
            Sunny,
            Clear
        }
    public class WeatherForecast
    {
        public string WeatherStationId { get; set; }
        public DateTime TimeOfDay { get; set; }
        public Condition Condition { get; set; }

    }
