I'm lost

I'm honestly not sure how to access the Tongue Length from the Frog class. Any tips on setting this up would be greatly appreciated.

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            int index = 0;
            for (int i = 0; i < frogs.Length; i++)
            {
                Frog frog = frogs[index];
                return TongueLength.Average;

            }
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }
}

Probably the most common approach to getting an average is to add up all the individual values in a loop, and then after the loop finishes divide that sum by the number of items (the array length).

Also, you can use the loop variable as the index into the array. You won't need to create a separate index variable.

Inside the loop, to access the Tongue Length of a specific frog object, use frog.TongueLength.

Thank you but what I'm wondering is how do I access the average of an array of class properties. I could get the average of frogs, but I don't know how to do the average tongue length.

I don't think you can actually get an average of "frogs" (what would that mean, anyway?). But as I said, you can calculate an average if you get the frog.TongueLength of each one, and add those all up in a loop, and after the loop is done divide that sum by the number of frogs.
