In the ParseWeatherForecast method in the Program.cs file, use int.TryParse to parse the Temperature property from the value of values[3] and add the parsed value to the weatherForecast object. Don't forget to declare the variable to hold the out parameter passed to the TryParse method.
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();
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;
}
return weatherForecast;
int temperature;
if(int.TryParse(values[3], out temperature) )
if(int.TryParse(values[3], out temperature) )
{
weatherForecast.Temperature = temperature;
}
}
}
}
using System;
/* Sample CSV Data

3,461 PointsThanks Eric it worked. 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();
weatherForecast.WeatherStationId = values[0];
DateTime timeOfDay;
if (DateTime.TryParse(values[1], out timeOfDay))
{
weatherForecast.TimeOfDay = timeOfDay;
}
int temperature;
if (int.TryParse(values[3], out temperature))
{
weatherForecast.Temperature = temperature;
}
return weatherForecast;
double precipitationChance;
if (double.TryParse(values[4], out precipitationChance))
{
weatherForecast.PrecipitationChance = precipitationChance;
}
return weatherForecast;
double precipitationAmount;
if (double.TryParse(values[5], out precipitationAmount))
{
weatherForecast.PrecipitationAmount = precipitationAmount;
}
return weatherForecast;
}
}
}
Now on this one its saying property precipitationChance not assigned. Can you help?

19,417 PointsYou want return weatherForecast last. It's in there several times so it is stopping at the first one.
So you would need to remove all of the return weatherForecast except for the one that comes after the precitptationAmount IF statement.

3,461 Pointswow you are such a lifesaver. Have to read and practise on the return keyword. Thanks Again
