not sure why this is not working not getting any errors

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;




                var lines = values[0].Split('\n');
                var Values = lines[1].Split(',');
                var Id = Values[0];


            if(DateTime.TryParse(Values[1], out timeOfDay))
                  {

                   weatherForecast.TimeOfDay = timeOfDay;

                  }

                weatherForecast.WeatherStationId = Id;




                return weatherForecast;

            } 
    }
}
WeatherForecast.cs 
using System;

maybe i have misunderstood the question i thought i was meant to get the weatherId value from the text in the csv file and assign it to the weatherForecast.WeatherStationId property how else do i access parts of this string with out using the split().

I get "Bummer: Index was outside the bounds of the array."

You don't need to split anything for this challenge. The "values" argument array can be accessed directly to get what you need. The comments in the "WeatherForecast.cs" file tell you which data item can be found at each array index.

The values are a string array, and each one is a separate array element. You won't need to split any strings, just select the correct one using an index. The comment could have perhaps made that more clear if they'd added brackets around the list:

/* Sample CSV Data
[weather_station_id,time_of_day,condition,temperature,precipitation_chance,precipitation_amount]
*/

You might want to suggest that to the Support folks if you think it could help other students.
