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

Am I instantiating the variable correctly?

Hi guys,

I divided the problem in parts and I think I've done all of the parts correctly. Can you point me where my mistake(s) is/are ?

I've worked and tried several aproaches, so I could really use some help now.

Thank you!

Program.cs
using System;
using System.IO;
// should I use this dependency?
using WeatherForecast;

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

        /*
        1. Create a static method named ParseWeatherForecast that takes a string[] parameter 
        named values and returns a WeatherForecast.
        */
        public static WeatherForecast ParseWeatherForecast(string[] values)
        {
            /* 2. Instantiate a WeatherForecast variable named weatherForecast and assign the appropriate 
            value in the values array to the WeatherStationId property. */
            WeatherForecast weatherForecast  = new WeatherForecast();

            /* 3. Use the sample data shown in WeatherForecast.cs to 
            determine which value in the array is the WeatherStationId. */
            weatherForecast.WeatherStationId = values[0];


            /* 4. Don't forget to return the weatherForecast in the new method! */
            return weatherForecast;
        }
    }
}
WeatherForecast.cs
using System;

/*

*/

namespace Treehouse.CodeChallenges
{
    public class WeatherForecast
    {
        public string WeatherStationId { get; set; }
    }
}

Hi Tiago!

For the most part you are instantiating correctly! One note though and you may have not covered this yet but since you're instantiating an explicit type with the new statement you can just declare weatherForecast as a var and C# will figure out typing for you.

Instead of:

WeatherForecast weatherForecast  = new WeatherForecast();

You can use:

 var weatherForecast  = new WeatherForecast();

The only issue I see with what you have is that using WeatherForecast; at the top there, that shouldn't be there. We use the using key word to reference namespaces out side of the one the current code is in (This is a rough summary for simplicity) since both Program and WeatherForecast exist in namespace Treehouse.CodeChallenges WeatherForecast can be called just as WeatherForecast. I hope that clears things up.

Thank you Tyler! Best answer! ;)
